pmdg 737 cabin altitude warning

Holger: Complexity is a term that is hard to define precisely in virtual aviation. I was landing at a high elevation airport (10,900 feet) and the cabin altitude warning came on. Should steel brakes or carbon brakes be simulated? In the first few days after the release, there were also some slightly disappointed comments from time to time. On final approach, I was only able to reduce to Vref right before the threshold. There is always something that hums, buzzes or beeps. Oski, how does the NGX run for you? 4 0 obj So we should really assume that everything runs normally. Thanks. In the PMDG, the whole panel is somehow less wide, everything in the VC seems more confined. PMDG 737 Cabin Altitude warning. Simply ignoring the alarm will lead to an almost certain crash, as shown by flight Helios 522, which never pressurised and crashed due to fuel exhaustion. Holger: Frank, who recently wrote the review for the DA-20 Katana, pointed out the cockpit crew animations to me. The image galleries on airliners.net dont really help either, because many of the images have been post-processed and stretched. The engines dont look entirely new from the factory, and the numerous official PMDG repaints are also a joy to behold. In the real world, after all, engineers go to incredible lengths to create a human-machine interface that is as optimal as possible this is true in many fields, but particularly in aviation. What is also great is that PMDG attaches equal importance to the visual aspect of the flight experience. When I browse various forums and seeinexperienced simmers asking questions on the level of what button do I need to press to take off, I do have to say that a certain level of expertise is required. Instead, it is an add-on for intermediate or even (very) experienced desk pilots. The Federal Aviation Administration (FAA) on Thursday warned of a risk that pilots and other crew members could lose consciousness if the cabin altitude switches failed. Oski: I hope it wasnt me who made that claim. Also, set the bleed valves to auto and the packs to auto. Its enough to consider an engine failure at or shortly after V1 and the correct response to this problem. There are a few isolated flaws, but in view of the huge complexity of the add-on they should not be overstressed.

A comparison would have to be made, though, across the whole range from the -600 to the -900. I checked failiures since i just wanted a routine flight and there was none, however it the horn was sounding. WebHow to align irs and fix cabin altitude warning (Zibo b738) - YouTube 0:00 / 3:06 How to align irs and fix cabin altitude warning (Zibo b738) FSimSpotter 5 subscribers 2.7K Press question mark to learn the rest of the keyboard shortcuts. I'm not up to speed on the pneumatic system as I'm not a 737 pilot IRL, but I suspect this is because you have the isolation valve set to open instead of auto. I have the same issue and cant figure it out either. By the way, practically all adjustments are made via the Flight Management Computer and take immediate effect without having to restart the simulator. The 2D panel concept has thus not been implemented completely, which I dont quite understand. If this is your first visit, be sure to For my taste, the NGX feels very good. Do this by clicking the username pull-down at the top right, then selecting "User Settings." Let me put it like this: The NGX autopilot makes about the same errors as a real autopilot and to a degree that is definitely justifiable and does not to be corrected. Also in the case are eight GB of memory and an Nvidia GeForce 570. This review was originally published in German on our sister site www.simflight.de and has been kindly translated by Martin Boehme. Are there any operations that can only be performed in the 2D panel? PMDG enable their customers to equip their aircraft as they please the real aircraft is available in different configurations, and the same is possible in the simulator. They use entirely different methods of calculation and therefore cannot yield the same results. In the PMDG, the whole panel is somehow less wide, everything in the VC seems more confined. Im guessing its the alarm that you arent in landing configuration, but I have set the flaps for landing, gear is down, speedbrake is armed, what else is required for the alarm to stop? . Full featured failures simulation to cover nearly all QRH scenarios as well as real-world mean time to failure simulations model. You will become aware of many details you would not previously have paid attention to. Oski: I would indeed make this recommendation in those cases where this experience has been gained with older FS aircraft. Native PMDG datalink simulation compatible with simBrief integration. Updated 737 options packages reflecting operational improvements and changes to the global 737 fleet. The other animations are also executed very well. And after all, the community is made up not only of pilots with virtual type ratings and hardcore simmers who plan and execute their flights with great dedication and knowledge, but also of many with an aesthetic inclination who frown at sludgy textures or mushy pixels and complain if exterior features such as pitot tubes or antennas are missing. Maybe I was just unlucky and happened upon one of these very few flaws. All of the various equipment and setup variants are also controlled via the CDU this is intuitive, and changes are made at once. There are a lot of things happening in the flight deck that can cause a warning. endobj Obviously, George also has problems from time to time with leveling off exactly at a given altitude or predicting a descent point precisely. #1 Tobble 11. But nothing conclusive can be said yet in this respect since the shorter variants have not been released. The following image shows an example of this that occurred with the SID RWY 28 ZUE 1V in LSZH. Of course, visual treats like these have their price. Ok thanks, now I know where to look. PMDG Customer Forums. Here at the Benzinger home, it is customary that I build a Revell model kit for every new FS add-on I buy and in this case, the PMDG model clearly beats it! I was a little surprised that the 737 NGX now has one after all. Posts that are unsigned will be quietly removed without comment by the moderators, so to make your life easy- we recommend enabling your forum signature so that you never need to remember. After all, every animated object has to be calculated dozens of times per second light incidence, reflections, shadows. I doubt, however, whether the majority of simmers will do this and in my view, it isnt necessary. Its the same sound as the takeoff config alarm, but I get it when landing. You may have to register before you can post: click the register You should welcome the existence of a 2D panel, I assume? I had something similar happen today, it was a pressurization problem. If you are hearing a long, continuous beep it is probably a configuration warning. It issued a directive ordering that airlines check them for faults. All trademarks are property of their respective owners in the US and other countries. They are normally turned off for take-off (because they use bleed air which in turn reduces engine power) but have to be turned on after take-off, otherwise the cabin cannot be pressurized. You can keep APU BLEED ON until 17,000ft to be usable but you do need BOTH PACKS ON AUTO and BLEED PACKS AIR ON AUTO. In general I do have to say that the FMC runs quite stably and without errors. Fully customized system simulation for all major and minor aircraft systems and components. A marketing and sales director in real life, he is also a beta tester and project consultant and has been with simFlight for ages. The exterior and interior model are based on the original blueprints from Seattle. Sign up for notifications from Insider! They were set to 38000ft cruise alt and 150ft landing alt on both occasions. Just two questions: what do T/C and T/D mean in the plan map? I use only a sub-woofer and two tweeters all in all, a pretty standard PC sound system. My old computer, a first-generation quad core with 2.93 GHz (QX6800) should probably be able to handle the PMDG, too, but a mixture of complex sceneriesandthe 737 NGX would definitely be pushing it! {[O `Zfh=Ie;Aup7fQV"+. <>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 23 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> But the thing that really amused me slightly was RSRs explanation for why the throttle quadrant was left out: He said it was due to lack of time. Holger: Stefan, if you look at photos of a real 737 NG and compare them with the PMDG copy, you conclude that it comes pretty close to the original. Stefan: Well, in direct comparison with other 737 NG implementations I have to say that overall, the VC in those implementations is noticeably lower, making the view through the forward window less high and wider. In the final evaluation, though, my opinion is that the NGX is still comparable to other complex aircraft add-ons. I dont know. Three companies are currently competing for the implementation of the best Boeing 737 NG simulation: iFly and PMDG and strictly speaking Ariane, too, though the latter product has been on the market for a few years and can no longer keep up with the other two. And at this point, I again need to make an important digression: As usual, I have read the whole spectrum of assessments in the PMDG forums from too sensitive to too sluggish. The way Oski describes it you probably dont have much time for wild mouse acrobatics. As a result of this, the A pillar in these airplanes is more inclined, and the bulge does not remind me as much of the nose of my former Latin teacher as the one in the PMDG. Upload New File; Discussion. Holger: Are there systems that are particularly innovative or that deserve particular attention? Once you have internalized the concept, you can conveniently operate the NGX to its full extent without any major investments in home cockpit hardware. 510 minutes are enough to configure the rest of the systems for home use. Special mention should be given to the lighting of the exterior model: The position lights that reflect of the ground just look great! Don O2 Masks and establish communications (boom to mask in the ACP) 2. But an expert in the sense of the question you certainly dont have to be that. I did not find any function that displayed any obvious errors. We got to discussing the behaviour of the autopilot in good Flight Simulator add-ons and real aircraft. Tom Allensworth, In 2003, by the way, he reviewed PMDGs Boeing 737 NG for FS2002 and FS2004, and he later went on to review the various Boeing 737 NG from Ariane, too. But I have every trust in the expertise of PMDGs team and in the communitys swarm intelligence. What is that sound for and how do I fix it/turn it off? This really applies to all of the working space of the captain. Representing years of work to to leverage the very best that Microsoft Flight Simulator can offer, the PMDG 737-900 is the fourth installment in PMDGs simulation of the magnificent Boeing 737NG series. Why do I have that red warning light and how can I solve it? Obviously, at least Im not the only one with a preference for 2D panels. It makes the transition to single-engine flight much too harmless. Oskar Wagner was a Captain with a large Swiss airline for many years, flying a large variety of types, and he also worked as a Fokker company test pilot flying new aircraft in preparation for delivery. Driveable pushback tug. Review : SXAirportDesign El Paso International Airport P3D5, Review : RFscenerybuilding Brussels South Charleroi International Airport P3D5, Review : Pro Flight Trainer PUMA X and Flight Sim Coach experience with MSFS, MLD Scenery LRIA Iasi Announced for MSFS, Configuration of the aircraft from the cockpit without a restart, Crash to desktop (CTD) on some systems (see PMDG support forum). This is already complex enough but can be carried out flawlessly with the present add-on. It has already been decided that, in addition the Boeing 737-800 and -900 reviewed here, there will be an update at a later date containing the -600 and -700, the two shorter variants. I have good frame rates (20+ for instance at Mega-Airport Zrich) when in the VC and even better frame rates (30+) with the 2D panels. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum. Each Boeing plane has two pressure switches on board as a safeguard in case one fails, following a 2012 FAA mandate. If it comes when you disengage the AP I think its in the manual - press AP disengage twice to silence the alarm. In such conditions, a flow experience will never come about. Once you start to achieve your first successes with this, you should be ready to hazard a step into a real Level D simulator and try your hand at the real thing. Then set the landing atltude at the destination and the cruise altitude. PMDG should really have deserved this distinction, which unlike the simFlight awards is awarded by the reviewers. Click here for more information and to see all donations year to date. Precision Manuals Development Group (PMDG) has followed suit and recently released their interpretation of the Boeing 737 NG. Can't figure it out. You didn't set the bleeds and/or packs correctly after your engine start. I say this because if the 2D FMC is on a secondary screen, you cannot use keyboard entry you can neither use the tab key nor activate the input line in the scratch pad. Read more: Amazon's Prime Air drone delivery team has had higher turnover than the rest of the company as launch delays and internal tensions roil the division. As I have already indicated, the visuals of the 737 NG exterior model are as a whole correct and feature many details. They are normally turned off for take-off (because they use bleed air which in turn I went to my doors page on the fmc and found that cargo hatch was left open and was unable to close it in the air. The first steps are PPAA -> Power Performance Analysis Action to achieve safe single-engine flight; next, we want to restore system redundancy to the degree possible while of course not forgetting to navigate and under coordination with ATC to manoeuvre to a position from which, after re-programming the FMC, a single engine approach can be made to the departure airport, if this is possible from a meteorological and operational point of view. This is not what the FCOM describes. What is your impression of flying the Bobby? Doing this at the full operational system depth would, in my opinion, definitely require too large an effort just think of the objections we hear that add-ons should be suitable for casual after-work flights. To me, the 737 NGX is by far the best and most innovative and so the most significant aircraft add-on in a long time. After further investigation and analysis, however, the airplane manufacturer and the FAA concluded in May that "the failure rate of both switches is much higher than initially estimated, and therefore does pose a safety issue.". To date, PMDG has not necessarily been known for eye candy; an accurate rating for the external models of previous years might be solid work. This was a release that the community has spent a long time waiting for after all, the airliner was initially announced for 2010. They don't add air to the cabin.Kevin Hall. Should the autopilot control be realistic or simplified? If this is your first visit, be sure to HiI have just done two flight in the 737-800NGX Winglets aircraft and on both at one point or another in climb i got the cabin altitude You also have the option to opt-out of these cookies. Oski: Particularly innovative is not something you can really call the NG and here I mean the real aircraft even if NG stands for New Generation. This is an extreme feat, and to us lay people, it is hard to grasp that it is even possible to execute such a procedure many times a second without a hitch. The FAA said in the order Thursday that if both switches failed, the warning system would not activate if the cabin altitude exceeded 10,000 feet at which point oxygen levels on board could become dangerously low and cause flight crews to lose consciousness, it said. There is always something that hums, buzzes or beeps. Edit: page 31 of the introduction PDF I turned off the autopilot, but I cant silence the alarm. The reason is simple: The PMDG B737 NGX has really been simulated almost completely in all systems including Flight Guidance, of course. In addition to the performance problems on older systems, which were to be expected, there were also reports of inexplicable crashes CTDs and freezes. In this respect, the NGX is a new benchmark by which many future developers as well as future alternatives to FSX as a platform will be measured. All times are GMT. Whether this particular behaviour is seen specifically on the NG is something I dont know. Yes, MLD Scenery develops payware products for sale at SIMMARKET https://secure.simmarket.com/mld-sc, when is this gonna be launched, it is gonna cost money? This means it is certainly worth your time to take a look at an up-to-date manual. Quite apart from the CTDs, the general principle of course always applies that where there is light, there is also shadow. This really applies to all of the working space of the captain. When I cant fix those I take out my headphones and just make a vroom sound to keep up the immersion. I learned that many airline pilots would sometimes welcome it if real autopilots flew as precisely as they do in the simulation. The basic concept takes some getting used to at first but should for the most part be familiar from previous PMDG products (particularly the MD-11). And this is why PMDG recommend a 64-bit system in their requirements. I was landing at a high elevation airport (10,900 feet) and the cabin altitude warning came on. I, too, was affected by this on several online test flights. For example, at low speeds it has the same difficulties in holding altitude precisely when rolling into or out of a turn as some of its big colleagues. I could really feel the large mass pushing: The aircraft was quite unwilling to lose airspeed and altitude. To what degree the data conversion performed by Navigraph is responsible for this cannot be determined. The Boeing 737-800 and -900 simply look incredibly good, too! The FAA said it doesn't have enough information yet to explain why the failure rate of the switches is "unexpectedly high" and recommended that airlines return any failed switches so that the switch manufacturer, which it didn't name, could investigate the issue. In principle, it does not take particular effort to fly. And there is an almost unlimited range of solutions to this problem. But lets put the 737 to the test, Captain! Each configuration can be tuned further to ones hearts content. Its great that this is possible today. OP is talking about a warning horn that sounds continuously. To read their verdict, click read more. PMDG recommends the use of a 64-bit operating system. This page was generated at 03:28. No ethical discussions about Piracy (mentioning that an add-on is worth the price is fine, but don't tell anybody directly to buy it instead), 3. Highly integrated exterior, interior cabin and flight deck sound environments. Also your yaw damper is off, turn that on on the ground. The Boeing 737 NGX is certainly not an airplane that can be recommended in good faith to an absolute novice. To be sure, the NGX sets new standards in a few areas that all future aircraft will need to be measured by but it also does have its flaws, even if they only marginally impact the overall impression. Here at the Benzinger home, it is customary that I build a Revell model kit for every new FS add-on I buy and in this case, the PMDG model clearly beats it! Holger: Sound is an aspect that should not be neglected after all, it accompanies us from the first click on the panel to the completion of the flight though we are usually unconscious of it. This website uses cookies to improve your experience while you navigate through the website. Holger: So the complexity of this add-on can definitely be learned and experienced without needing a Level D simulator to do it. But I dont want to overstress this. Does the PMDG fly precisely? It really is a joy to work with. Its available on the developers own store and Orbx Central for $28.95 and comes with the following features. It added: "Addressing these failures requires immediate action.". Stay up to date with what you want to know. iFly released their Boeing 737 NG fleet only a few weeks ago, and we reviewed it here. and much much more! We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. The aerodynamic purpose of this is not quite clear to me, but it is definitely beautiful to watch. Holger: Can you give an example of a particularly well-implemented complex workflow that is possible with the PMDG aircraft if you exploit it to its full potential? Holger: The complexity is of course not restricted to the systems simulation but continues with the visual model. Created by the most recognized and experienced team in desktop flight simulation, the PMDG 737 for Microsoft Flight Simulator is an incredibly detailed, feature rich simulation of the ubiquitous Boeing narrow body. Well, in direct comparison with other 737 NG implementations I have to say that overall, the VC in those implementations is noticeably lower, making the view through the forward window less high and wider. However, I have to deduct more than a few points for one of my favourite procedures, the automatic go-around. To me, the acoustic environment in the cockpit is tightly woven and convincing. Forums. Why dont I say it deserves the maximum rating? Giuseppe Nelva We start a release, the DHC-1 Chipmunk, which was launched by Aeroplane Heaven. Or if the FMC crashes completely because sloppily programmed clickspots cause me to flip the wrong switch on the overhead and power down the flight computers? A full featured tutorial will guide you through proper operation of the 737 from power up to power down. Did we ever figure out what caused the dual bleed trip? Below the pack switches, turn the engine 1 and 2 bleed on. The only weakness I have found in this regard is the way the engine loses thrust when the fuel lever is closed. In the beginning, the acoustic backdrop seemed almost too loud to me, but if I hark back to the pre-9/11 era I recall that various airliner cockpit visits at the time really left a similar impression on me. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum. Having the isolation valve in open instead of auto certainly wouldn't do it; neither would climbing 1,000ft above your set cruise altitude. Youre completely right. In this way, I can at least compare between similar aircraft. PMDG Operations Center 2.0 for easy livery installation and ease of receiving free product updates from PMDG. stream The customer has the choice. Very informative review. Holger: When the BAe Jetstream was released, Robert Randazzo, the head of PMDG, wrote that there would be no more add-ons with 2D panels. This is very inconvenient and detracts from the overall impression. Ive had to wait a long time for this convenience the last payware product that offered this luxury was the Super 80 Pro by Coolsky/Flight1. I fly using TrackIR, and I dont need the 2D panel at all. However, it said that in September, an unnamed airplane operator reported that both switches had failed on three different 737 models it tested. It is reassuring, though, that the developers are hard at work on a solution, and we are sure that PMDG will soon be able to offer such a solution. But please give PMDG a bit of time its not even two weeks since the release yet. I don't think those will cause the horn to go off. PMDG has managed to implement a very exact simulation of the Boeing 737 NG for FSX that does not leave much to be desired. This is accomplished without overly large rudder deflections and is easy to stabilize my feeling, as I have already mentioned, is that it is a little too easy! The FAA requires every airplane with a pressurized cabin to include a system that warns the flight crew of cabin depressurization. With the characteristic eyebrow windows or without. WebPMDG Failure Name in FMC: PRESSURIZATION -> PRESSURE HULL INTEGRITY Note 1: Trigger this failure above 14,000 feet Note 2: The Cabin Altitude warning horn is your Holger: I always enjoy it when an add-on surprises me. Press question mark to learn the rest of the keyboard shortcuts. The reason is simple: The PMDG B737 NGX has really been simulated almost completely in all systems including Flight Guidance, of course. As above. Oski: My current system consists of an i7-960 @3.2 GHz, 6GB triple channel memory and two GTX285 graphics cards with 3 displays in total. Where can I find HGS Settings to setup the approach? No doubt there will always be some room for discussion whether the trim sound, say, is too quiet or whether the spoiler extension on landing sounds quite so or a bit different. The Federal Aviation Administration (FAA) on Thursday warned of a risk that pilots and other crew members could lose consciousness if the cabin altitude switches 1 0 obj Which of the implementations conveys the most realistic feeling of space? My specs are: Intel Core i5-2400 CPU 3.1GHz, 8 GB RAM, Windows 7 64-bit and nVidia GeForce GTX470 with 2 displays or one display for the 2D panel and a projector for the external view. Max landing altitude is 8400. The image galleries on airliners.net dont really help either, because many of the images have been post-processed and stretched. You need to set the outflow valve to auto. You are the connoisseur among us, with an eye for correct design. But opting out of some of these cookies may have an effect on your browsing experience. I have to say, though, that I dont have any real aircraft experience to compare to, nor do I have the time to climb into one of the fixed-based simulators in my vicinity. No political discussions, go to reddit.com for that, 6. This is one of the few rigid rules that we enforce regularly. Before we get down to the meat of the review, we briefly want to characterize the PMDG Boeing 737 NGX in the wider context of the current add-on market. Would be nice if the plane could tell you on a PFD. <> You will find the signature editor on the ACCOUNT tab, about half way down the page. . To me, personally, the interaction concept of a panel is one of the topmost quality aspects of an aircraft add on. When in AUTO MODE, or ALTERNATE (ALTN is a second automatic function, same as the AUTO mode) there is no way to reach the cabin altitude warning pressure. Accurate resolution cockpit displays Currently studying Aeronautical Engineering at Sheffield Hallam University (UK). With a bit of practice, the FMC can be programmed in 10 minutes at most. Has PMDG thought of pilots like you? What this means in practice is evident to the customer the first time they load the 737. The aircraft they have delivered this time round, however, is really quite beautiful and modelled in great detail; it even features a cabin that is visible from the external view, which is not really typical for PMDG. Stay tuned! endobj Is it even possible that this PMDG software can simulate a Boeing 737 realistically? % I stoppped the first flight and later did another that went the same way. At least in normal conditions.The controllers are programmed and designed to never exceed maximum differential pressure between cabin and external air, this thing takes its part in the pressurization profile that controllers make when they know the desired crz altitude and landing altitude.Wrong data are only uncomfortable for passengers and crew.Different is for the manual mode where the pilot manually moves the valve.In this case there is only the overpressure protection wich will open the safety valves when maximum differential pressure is reached.There is no protection in manual if the airplane is de-pressurizing (except for the warning). "A latent failure of both pressure switches could result in the loss of cabin altitude warning, which could delay flight crew recognition of a lack of cabin pressurization, and result in incapacitation of the flight crew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane," the agency said. It repeatedly happened to me that the flight path displayed on the ND contained inconsistencies. Oski: In simming, expert is always a relative term. Firstly it's amazing!!! However, a few isolated but relevant problems will definitely still have to be fixed. Oski: To a certain degree: yes! My specs are: Intel Core i5-2400 CPU 3.1GHz, 8 GB RAM, Windows 7 64-bit and nVidia GeForce GTX470 with 2 displays or one display for the 2D panel and a projector for the external view. After all, this is an add-on that has been awaited for a very long time, with the focus of interest lying on the desire for a realistic implementation of the real aircraft. But these are minor points, and moreover they depend on subjective perception. You didn't set the bleeds and/or packs correctly after your engine start. Work through that section of the checklist again on your next flight. Hav is there a way to increase the max cabin altitude setting that is allowed before the alarm is triggered. I just muted the game tho and carried on unpressurized . Is the first impression misleading? Check your pressurization panel. The hydraulic cylinders of the slaps and flaps are also modelled in 3D. But these are minor points, and moreover they depend on subjective perception. Cant seem to find anything other than the P3D one, This alarm is not the AP disconnect, it's different. I suppose a cockpit is anything but a quiet place. Oski: Well, its always a bit difficult to judge the sound on a PC.
