Yeah, well, they can go eat poo poo and find a new instructor as I shop for jobs with TBM time-on-type And actually, I think I could not do this in Canada because the TBM requires a type rating according to our regulations. PC-12s do not, though, so

Did it affect the landing gear as well, or are they buried somewhere under there? I assumed they bellied, and it looks like a hull loss. An-124s are tough basterds, though. e: OK gear down & in the snow. Maybe not that bad (from the excursion), then PainterofCrap fucked around with this message at 02:55 on Nov 14, 2020 |

I flew with a guy for a flight when my regular CFI was unavailable, he had let his CFI lapse for a decade or two and had just gotten recurrent, so he was offering to do freebie instructions to get his name back out there. To illustrate a point about engine failure he cut power at like 300ft after take off when we were still on runway heading, yanked us around at a steep bank to land back on the runway we had just taken off of, and made no radio calls the entire time. If he had turbine time, that CFI would do it. It's not necessarily related, but a few weeks later the 100hr on that plane found a decent size crack in the spar.

So when the electrical failure is complete, how does the aircraft not become completely unflyable? (I know it varies, but to this layman complete electrical failure sounds just this side of "the wings fall off".)

In this case I’d assume that they lost all electricity generation for whatever reason (more than one engine must have a generator, right?) and just had battery power for like the radio. Control surfaces and landing gear would still work however. hobbesmaster fucked around with this message at 17:31 on Nov 14, 2020 |

Radio going dead could also just mean shrapnel hit the antennas but regardless they clearly still had hydraulics to some extent

Nebakenezzer posted:So when the electrical failure is complete, how does the aircraft not become completely unflyable? (I know it varies, but to this layman complete electrical failure sounds just this side of "the wings fall off".) The control surfaces are generally controlled both hydraulically and manually, with multiple redundancy. If you lose electrical power, that doesn't affect the hydraulic system in most airplanes, which is pressurized with engine-driven pumps; if you're in a new plane that uses electric pumps, or both engines blew up and you lost pressurization, then you deploy the ram air turbine to get pressure back. If the RAT doesn't work, you likely still have a manual linkage that moves the control surfaces when incredible effort is applied to the control column. In small airplanes without hydraulic systems the controls aren't affected by electrical power at all (except for maybe trim and flaps), so it's not an issue.

If there isn’t some standby direct connection to the trim tabs or similar they will have a battery or other source of emergency power (RAT, EPU, etc) dedicated to running the systems necessary for some level of flight control for some period of time.

looks like a fan blade passed straight through the wing root box, which probably severed a wire bundle that resulted in electrical failure. backup generators and other engines won't help if the physical cabling is cut. as noted, though, even then they were still able to maintain control of the aircraft and land it.

Z the IVth posted:Complete layman here. Does this statement still apply to "fly-by-wire" aircraft (fighter jets I assume). No, fly-by-wire jets need electrical power to fly, and the planes are designed with that mind. The F-16's control stick, for instance, only moves about 10 degrees in each direction, so even having a direct hydraulic connection as a backup wouldn't make much sense. Fly-by-wire jets have multiply redundant electrical and hydraulic systems, and an emergency power unit in the case that all the primary systems fail. In the case of the F-16 it's got a hydrazine-powered emergency turbine/generator that will keep the computers running and hydraulics pressurized long enough to make an emergency landing, hopefully. Godholio posted:It does not. And I'd like to see one of our resident large aircraft pilots to confirm if it applies to modern airliners as well, because I seriously doubt it. I also am curious about whether FADEC turbine engines can fall back to some sort of manual/mechanical operation in the case that the computer craps out, or if they just shut down.

Fighter jets, like all cowardly aircraft, are equipped with a backup aircraft in case all systems fail.Sagebrush posted:I also am curious about whether FADEC turbine engines can fall back to some sort of manual/mechanical operation in the case that the computer craps out, or if they just shut down. Specifics depend on the engine and controller, but yes. Depending on the failure you may not be able to re-light it, and you may not get indications, but there are turbine engines whose fuel systems basically fail to becoming carburetors, with some asterisks. Other edit: a secondary google as a translate between civ and mil defines FADEC as 'no manual control possible' which is an odd cut line to make, but I'd bet it's engine specific still.

The flying bits are in the minority in this clip, but it fits in this thread as well as several others within the same topic space I figure. https://www.youtube.com/watch?v=LcggNe-SEXU I really like these 60 fps upscales that are all over youtube these days. There's something about the machine learning interpolation that lends itself well to filling in the blanks between the frames of old footage. There aren't many noticable artefacts either. If you pause and step frame by frame with the period key, you can see one example on dust specks. They appear only on one frame on the real film, but they are interpolated as growing from a tiny point, being a dust speck, then vanishing again. With low detail and high contrast anyway, the algorithm has an easy job.

Sagebrush posted:I also am curious about whether FADEC turbine engines can fall back to some sort of manual/mechanical operation in the case that the computer craps out, or if they just shut down. On the PW150A, FADEC is required for the engine to function, but the system is designed in such a way that losing both engines to a FADEC failure is incredibly unlikely outside of the airplane being hit by an EMP or something. Once the engine starts, the FADEC system on each engine is powered by a dedicated alternator that doesn't rely on the aircraft electrical system at all, and the FADEC systems also don't connect in any way, so one can't fail and take the other with it. If there's an issue with the FADEC in flight, it'll just log minor faults without notifying the crew, but more significant issues will result in it throwing a master caution to warn the crew that engine response may be degraded and they need to watch that engine limits aren't exceeded. For serious failures, it'll generate a "FADEC FAIL" warning, which does require the crew to shut down the affected engine, if the FADEC doesn't shut it down automatically. If the FADEC system logs too many small faults over a given time, it'll wait until the airplane is on the ground, and then show a message that says "powerplant", which means the crew goes to get breakfast (or whatever meal is convenient), since maintenance has to interrogate the airplane and replace whatever was causing the faults before it can fly again. As far as I'm aware, in something like 15 years of operating that engine, my airline has never had a FADEC completely fail, but there have been cases where it's commanded an engine shutdown because it caught something like a bearing seizing and killed the engine before the problem got worse or the crew was even aware of what had happened.

Ackhshully, the FADEC on a turbofan aircraft should live through a pretty beefy EMP according to the FAA required HIRF and EMI test levels.
