are there any fun facts / hot takes about the dash 7 or 8 (other than being canadian)? i only fly in flight sims but to me they're both some of the coolest-looking civilian planes and i think turboprops are neato  the twin otter is very cool as well imo, a stubby little sibling  otherwise what's the coolest-looking civilian airplane? vvv oh drat yeah, extremely cool vvv that reminds me of the lear fan 2100

i am not a pilot but i play one on the computer, but: wouldn't it be fairly straightforward to have an alarm alert the crew based on pressure/o2 level? it seems like high altitude + low/no cabin pressure is a state you wouldn't typically want to have the airplane in so an alarm would be good, but again i do not know what i'm talking about edit: i do watch a whole lot of that air disasters show so i'm at least marginally qualified the milk machine fucked around with this message at 20:55 on Jun 5, 2023 |

yeah that’s definitely true. I guess I’m thinking of things like a takeoff config warning or gear warning, etc, but now that I think of it maybe those are features that aren’t required for smaller planes

if the decompression is slow or the cabin pressure setting is misconfigured it may take a long time to become dangerous, i don't think you'd need much of an alarm for a sudden loss of pressure a ground proximity warning only gives you a few seconds as well and planes still have them

there was an airbus that had a windshield failure at 30k+ feet and the copilot got halfway sucked out. the pilot couldn't get to his mask because he would have had to let go of the side stick, so he just descended and landed the plane without suffocating or freezing. everyone survived, even the copilot. it happened over the himalayas iirc

ImplicitAssembler posted:Hmmm? A windshield failure shouldn't prevent him from letting go of the stick. the copilot was wedged halfway out the window and his knee/leg was against the other stick, idk, i assumed it had to do with how an airbus accounts for conflicting inputs or something bull3964 posted:Unless it's a different one, I think you are referring to BA 5390 and it was a BAC One-Eleven Series, not an airbus. No side stick, one of the issues was that the cockpit door came forward with the decompression and wedged itself on the flight controls. i looked up the one i'm talking about, it's sichuan 8633: https://en.wikipedia.org/wiki/Sichuan_Airlines_Flight_8633 they had a similar door issue where the door blew open and banged an electrical panel, popping a bunch of breakers

two_beer_bishes posted:The jet I fly has an auto emergency descent mode if the cabin altitude gets too high without crew action. It turns 90deg left, descends to 10,000ft and squawks 7700 to get ATC's attention. Obviously not every jet has this but it's cool to watch in the sim. that's cool. what kind of jet is it? also, is the left turn intended to be another signal to atc that something is up because of the sudden direction change?

seems like there are at least a few examples of pilots dealing with decompression successfully despite several minutes without o2, so it seems like there’s more going on than “you die after a couple seconds”

Nebakenezzer posted:Can you give some examples of what you mean? yes, when you lose cabin pressure you lose o2. there was a video posted earlier of a pilot talking with ATC that was able to recover and land, and there are several examples of flights where the pilots spent several minutes or more without supplemental o2 and not only did they not pass out, they landed the plane. for example, sichuan 8633: https://en.wikipedia.org/wiki/Sichuan_Airlines_Flight_8633 since the original conversation went something like "you don't need an o2/cabin pressure warning because you pass out in a few seconds" it doesn't really seem like hypoxia or low o2 levels are quite that simple (nevermind that that ignores an o2 situation that happens gradually) the milk machine fucked around with this message at 17:18 on Jun 13, 2023 |

i am. are you suggesting the pilots had enough oxygen because they were flying fast enough they achieved a low-enough cabin altitude due to the air blowing into the windshield? that seems very unlikely but it's not a factor i've heard suggested before e: looks like dynamic pressure at 500 kt and 30k ft is a little over 2psi? so maybe a tenth of an atmosphere the milk machine fucked around with this message at 17:41 on Jun 13, 2023 |

Sagebrush posted:This doesn't say anything about whether the pilots put on their oxygen masks when the window blew out. I have to assume they did, because at 30,000 feet you have seconds of consciousness, and no these aren't special superhero pilots who defied the rules of human biology because they tried really hard. this has a little more info: https://samchui.com/2023/05/25/miracle-of-sichuan-airlines-flight-8633-first-officer-sucked-out-of-the-cockpit/ the co-pilot who was halfway out the cockpit was jammed against the side stick, so the pilot couldn't let go of his side stick to get his mask. he was maskless through the whole thing

2psi is 2psi, it’s pretty hard to go fast enough that air can’t get out of its own way until you get towards Mach 1, and the air density at 30k ft is obviously low it doesn’t seem like you could get significant cabin pressure into a windshield-less plane by flying fast but I’m honestly guessing here though it would be funny if the “windshield blew out” checklist says to go full throttle into the wind

big companies use all kinds of janky enterprise messaging systems for employees to communicate because they have lots of requirements to retain data (which of course on the flip side is license and incentive to shred everything they can as soon as nothing requires them to keep it) i can't load the doc to check but i would expect (hope maybe?? it IS boeing.....) that "text message" means something on Teams or some similar kind of managed system. legal jargon hasn't really caught up with technology so you'll often see "text message" to mean electronic things that aren't emails or letters or w/e still not a very good system for documenting anything but it would be "official" e: vvvv yeah stuff like that too! the milk machine fucked around with this message at 00:26 on Feb 7, 2024 |
