WebCabin Altitude: Controllable or Uncontrollable 10,956 views Sep 26, 2020 190 Dislike Share Boeing 737 Pro 1.83K subscribers Following a rapid depressurization, this video shows Whether this particular behaviour is seen specifically on the NG is something I dont know. The present 737 interpretation from PMDG, to me, is the climax of this development (for the present?). The horn only goes off if the cabin alt goes too high. Powered by Discourse, best viewed with JavaScript enabled, is there a way to turn off this warning/alarm? Nothing to do with the ALT horn going off Paul.The horn will sound if the Cabin Altitude reaches 10,000.That would rarely happen in the RW.Fred. 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. Each Boeing plane has two pressure switches on board as a safeguard in case one fails, following a 2012 FAA mandate. Press J to jump to the feed. Leaving recirculation fans OFF would not prevent pressurisation. All they do is allow the packs to run at a lower airflow rate to improve fuel econ Also, set the bleed valves to auto and the packs to auto. 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. Holger: but the virtual cockpit is of course completely sufficient! Check if the packs are turned on. Just two questions: what do T/C and T/D mean in the plan map? The commitment that this requires in terms of cost and time should not be underestimated. Look for "Edit Post Signature." Note: To update navigation data, you can use the Navigraph PMDG 737 NavData from this post (pmdg_737_msfs_XXXX.rar). After starting engines set the top three switches to auto. There is always space for improvement, and there are also a few noticeable flaws that remain to be corrected. Also in the case are eight GB of memory and an Nvidia GeForce 570. And this is a good thing after all, there are already more than enough other freeware and payware options for novices .This is not a game, this is a simulation of a working environment. I dont think much of the superlatives that are so commonly used today. There is an Alt horn shut-off button its on one of the pressurization panels, if you press that one you will get rid of the alarm sound for the rest of the flight. Firstly it's amazing!!! The customer has the choice. An impressive experience! 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. endobj The reason is simple: The PMDG B737 NGX has really been simulated almost completely in all systems including Flight Guidance, of course. Obviously, George also has problems from time to time with leveling off exactly at a given altitude or predicting a descent point precisely. Why dont I say it deserves the maximum rating? There is always something that hums, buzzes or beeps. Whereas only a few months ago there was talk in forums and magazines about of a crisis of flight simulation, new developments are now coming thick and fast in the shape of high-quality releases. The engine sound, on the other hand, comes across as quite convincing. 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? Be sure to click the "Show Signatures" box. This makes sense because I 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. After all, every animated object has to be calculated dozens of times per second light incidence, reflections, shadows. 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. Also, flaps and spoilers have to be assigned to a key combination or joystick axis if you want to fly in 2D mode only, or you have to switch to the VC to operate them with the mouse. But these are minor points, and moreover they depend on subjective perception. Stay up to date with what you want to know. We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. Hey I managed to taxi to the runway with an open L2 door in the 777 just noticed it You can also use the RESET in the event one side falls down. Maybe I was just unlucky and happened upon one of these very few flaws. We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. Here's an adaptation of a two pilot job for the sim: 1. Of course, visual treats like these have their price. For example, this applies to the air conditioning sound and more seriously to all of the altitude callouts including the altitude warning. I really took the system to its extremes here. Not too lazy and not too agile. 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. But lets put the 737 to the test, Captain! 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 warning hor A home PC in a standard configuration is enough. Oski: Well, its always a bit difficult to judge the sound on a PC. Hit trip reset and switch iso valve to auto. Dont forget in Flight Simulator, we move in a three-dimensional world where the position of the sun, the view of objects and the world, the depiction of weather as well as animations, systems logic and high-resolution textures have to be computed anew with every frame! There is one thing you simply have to realize today: Given the high memory requirements of complex simulations, youre simply better off with a 64-bit system because, as a rule, the address space is large enough in contrast to 32-bit systems, where you quickly reach the limits. 3 0 obj No requests for older versions of an add-on, this is pointless almost always due to new features/fixes. This also implies that single engine flight is simulated quite well at least in terms of performance. Theyre wonderful, dont you think? All they do is allow the packs to run at a lower airflow rate to improve fuel economy. Some of these crashes are even accompanied by a blue screen. You also have the option to opt-out of these cookies. It has nothing to do with the cruise alt setting or the land alt setting. To what degree the data conversion performed by Navigraph is responsible for this cannot be determined. NOW WATCH: Why in-flight WiFi is so slow and expensive, 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. Holger: Frank, who recently wrote the review for the DA-20 Katana, pointed out the cockpit crew animations to me. And of course this entails that you need to obtain the necessary documents and work them through. Access your favorite topics in a personalized feed while you're on the go. But these are minor points, and moreover they depend on subjective perception. 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. Doubt PMDG modeled this. PMDG obviously did not want to expose themselves on this flank, which is why the add-on contains a balanced mixture of detail and functionality, without losing itself in resource-hungry bling-bling a la CaptainSim. I dont know. 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 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? It issued a directive ordering that airlines check them for faults. Once you have internalized the concept, you can conveniently operate the NGX to its full extent without any major investments in home cockpit hardware. Emi is a IRL 737 pilot and most everything you need to know is well described in the various vids on his channel. Which of the implementations conveys the most realistic feeling of space? Information Developer: Precision Manuals Development Group, PMDG Distributor: PMDG Home page:http://www.precisionmanuals.com/ Price: 69,99 US $, available through PMDG, Authors: Oskar Oski Wagner Dr. Stefan Benzinger Holger Kistermann. Holger: Performance is a good key word. Valve Corporation. 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). All new hi-fidelity models with superb detail Beautifully crafted exterior and interior models built over contemporary detailed plans and 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. In addition to the performance problems on older systems, which were to be expected, there were also reports of inexplicable crashes CTDs and freezes. You are the connoisseur among us, with an eye for correct design. 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. Then set the landing atltude at the destination and the cruise altitude. 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. Holger: I always enjoy it when an add-on surprises me. Forums. Special mention should be given to the lighting of the exterior model: The position lights that reflect of the ground just look great! Special mention should be given to the lighting of the exterior model: The position lights that reflect of the ground just look great! I, too, was affected by this on several online test flights. Even a few years ago, flight instructors in airliner flight schools would have shaken their heads at the mere thought. 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 Its enough to consider an engine failure at or shortly after V1 and the correct response to this problem. 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. 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 think if you press trip reset on the air con panel it should extinguish Ryzen 9 5900X, RX 6900XT, 32GB DDR4 RAM @3600MHz, 4k. Adrian Howe. Wonderful! And there is an almost unlimited range of solutions to this problem. PMDG should really have deserved this distinction, which unlike the simFlight awards is awarded by the reviewers. Do this by clicking the username pull-down at the top right, then selecting "User Settings." is there a way to increase the max cabin altitude setting that is allowed before the alarm is triggered. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum. I tried pressing the master caution and warning buttons, but the alarm kept going off. Oski: I would indeed make this recommendation in those cases where this experience has been gained with older FS aircraft. Surprising, but its a fact. Create an account to follow your favorite communities and start taking part in conversations. It is very nicely done and deserves a very good rating. 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. 1 0 obj stream check out the. There is no perfect add-on! If we want to count all of the lateral and vertical flight guidance by the FMC with LNAV and VNAV as part of automatic flight, we have to begin noting the first imperfections. It is, after all, more realistic in the end if all necessary instruments and systems are in plain view. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. The engines dont look entirely new from the factory, and the numerous official PMDG repaints are also a joy to behold. Its very annoying and I ended up having to turn cockpit warnings volume to zero in the MSFS settings). . Thats correct. After this review, we will write a comparison between PMDG and iFly. If there is something to find fault with in comparison with a real autopilot it would be that turns are sometimes initiated a bit harshly in normal LNAV cruise. This page was generated at 03:28. Non related things I saw : Your off schedule descent is telling you, you never reached that altitude. Today, he consults for and tests various Flight Simulator projects. But it is only natural that the cooperation with Boeing which has been stressed time and again and the use of original plans and blueprints should also have its effects here, and not only on systems depth. You took the time to be here, we want to get to know you. I have the same issue and cant figure it out either. 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 Quite apart from the CTDs, the general principle of course always applies that where there is light, there is also shadow. Do you have a link to the manual? You cant improve on perfect syntactically maybe, but not semantically. The aerodynamic purpose of this is not quite clear to me, but it is definitely beautiful to watch. Do this by clicking the username pull-down at the top right, then selecting "User Settings." 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.". No attacking of other commenters (including insulting, threatening, trolling, baiting, flaming), 2. No, on the contrary: To start the engines, you. At this point I do not want to enter into the tiresome discussion about different V-speeds, for instance between TOPCAT and FMC. The NG, too, can perform a go-around from a fail-operational dual autoland configuration, but the NGX cant. Frank Schmidts review of the Diamond Katana might have something to do with that I now have an i7 Sandy Bridge processor (2600K) that runs at up to 3.8 GHz. Now my wife's greatest friend's I from the. If it werent for the CTDs! But this is something I generally dont do after all, I want to assess the sound of the model I bought, not the model I fiddled around with. Tom Allensworth, 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. You need to set the outflow valve to auto. However, a few isolated but relevant problems will definitely still have to be fixed. What use is the most detailed systems simulation if I have to click through three sub-panels in critical phases of flight with high workload? PMDG obviously did not want to expose themselves on this flank, which is why the add-on contains a balanced mixture of detail and functionality, without losing itself in resource-hungry bling-bling a la CaptainSim. On the one hand, the specific sound system has a strong influence. as well as other partner offers and accept our. In addition to the performance problems on older systems, which were to be expected, there were also reports of inexplicable crashes CTDs and freezes. The directive includes the 737 Max. 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. As a user, you dont have total control over all sound levels except, that is, if you have some knowledge of the sound.cfg file and fiddle around with it. What is your take on the sound, Stefan? I was a little surprised that the 737 NGX now has one after all. Check if the packs are turned on. i just diverted my flight after 30mins so i could shut the aircraft down. PMDG 737 for MSFS. My experience with real world autopilots has been consistently good and definitely on the level of simulator autopilots if I may make the comparison in the reverse direction for once. I hope no one is going to claim that they use the VC to carry out the complete initialization of the FMC, for instance. Why do I have that red warning light and how can I solve it? There is always something that hums, buzzes or beeps. To me, at least, part of the fun of simming consists of flying different aircraft types. Another example: The elevators have trim tabs with their own animations at extreme deflections, they move in opposite directions. You will become aware of many details you would not previously have paid attention to. The order makes mandatory a recommendation that Boeing issued to customers last month. Don O2 Masks and establish communications (boom to mask in the ACP) 2. There is a 12,000 foot mod. Cant seem to find anything other than the P3D one, This alarm is not the AP disconnect, it's different. But before we can award the reviewers choice to this add-on, PMDG needs to fix the CTDs for good and then we will follow through. My solution to this has been the VRInsight MCP combo on one hand and a touch screen on the other. This means it is certainly worth your time to take a look at an up-to-date manual. Stefan: No, on the contrary: To start the engines, youhaveto switch to the VC to open the fuel valves. So we should really assume that everything runs normally. 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.
