My brain initially read that as E30 and all I could think was "suspension bushings."

In this former aviator's opinion, the engine wasn't supposed to do that.

If that's what a compressor stall looks like, jesus loving christ. We had flights where there would be a series of multiple compressor stalls just seconds apart. BANG BANG BANG BANG BANG Edit: V Yeah, the first time I had that happen (I wish I knew if it was all the same jet or not) I was convinced we were going to die. I think it was a 966th sortie, so there were about 25 students making GBS threads themselves, plus a few instructors. Godholio fucked around with this message at 23:56 on Jun 24, 2013 |

BANG BANG BANG BANG BANG ya, they're super dramatic but pretty harmless. One of the AWACS in Alaska would compressor stall practically on command during takeoff. It was an amazing party trick.

I once was on a 777 that had one of it's fadec boards die during spool up at the threshold. Followed by ~2hours of sitting in the sizzling heat at SFO. Some of the other passengers were a tad... hesitant about the second attempt at a take off. Me? I just figured we had a brand new fadec board (I have no idea why they decided to change it in situ rather than scrub the flight, but then it was united so  ) without any wear and tear.

So what would have happened if that had gone just after rotation or a few seconds into the initial climb out? I travel for work. I really should avoid this poo poo.

They would be fine. Takeoff data is predicated on an engine failure and being faster than v1 or decision speed as it is also known as. Hope that helps.

Just to confirm, that means that given equipment, load, and conditions the pilot has determined the speed necessary to safely take off even if one engine fails, and rotation does not occur until that speed is met?

V1 is a min speed requirement so yea once v1 is hit, the takeoff can be continued safely in case of an engine failure or another problem or the takeoff roll can be aborted (a reject call will be made signaling this) and the jet can be safely stopped with remaining runway available. Basically what this means is the flight deck is STOP STOP STOP *v1* GO GO GO. It takes something big to stop a jet after V1 since many problems are easier to deal with in the air rather than risk stopping a heavy jet at high speeds.

SybilVimes posted:I once was on a 777 that had one of it's fadec boards die during spool up at the threshold. Followed by ~2hours of sitting in the sizzling heat at SFO. There's a lot going on behind the scenes that means it's far more preferable to take a 2 hour delay than cancel a flight or transfer everyone and everything to a spare airframe if you have one. About the only situation I could see it making sense to scrub the flight would be if it was nearly empty and there was another one departing for the same destination in less than 2 hours that you could all fit all the pax on and you had no time sensitive cargo on the old flight, and the routings meant that the airframe you were on was fine to stay in SFO and didn't have to be somewhere else.

Compressor stalls are pretty much no big deal in any modern turbine, unless they are multiple and severe. The Lycoming LTS engines in the BK-117 I work in are very sensitive to vortices induced compressor surge/stall. We have to wait an extended time before transitioning an airport after heavies take off.

That 330 was a Roller though, so it might not even need a boroscope inspection if the parameters were ok and it didn't swallow something it shouldn't have.

Of course if you fly through a flock of birds and lose both engines you're hosed. Well, unless you have more altitude, a body of water and Sully in command.

Full on auto rotations are supposed to be pretty jarring right? I mean, do people perform those maneuvers for real and not damage the helicopter?

It depends on the aircraft. Some are very forgiving in an auto (B206) and others are not (EC135) A full stop, engine-out auto is a difficult move to land successfully. And by successfully, I mean to the extent where the helicopter can be rebuilt. The cyclic has to come back IMMEDIATELY without hesitation, as the collective is dropped. The military practices these often, civilian pilots do not.

The Ferret King posted:Full on auto rotations are supposed to be pretty jarring right? I mean, do people perform those maneuvers for real and not damage the helicopter? Yes. If you want a license, you need to be able to perform autorotations, which means practicing them. I watched one trainee at Rucker skid his UH-1 across the ground pretty far, but it was wet grass so I'm sure that helped. Didn't break the bird or anything.

Right but you don't actually cut the engine for the practice maneuver. I just thought the difference could explain the reason for the hard landing. As a certificated helicopter pilot, she clearly had been able to demonstrate auto rotations at some point. The Ferret King fucked around with this message at 02:42 on Jun 26, 2013 |

The Ferret King posted:Right but you don't actually cut the engine for the practice maneuver. They don't have to be jarring, but those Robinsons have a VERY low-inertia rotor system, so even a tiny bit off of perfect and you hit the ground hard. My CFI flew helos, and liked the Hiller more than the Robinson because of its huge all-solid-wood rotor blades and the fact you could be halfway lazy for autorotations. The offset of that was that he could get into a hover at 6000' density altitude with the Robinson, not so much with the Hiller. For the demonstrated autos, you have to release the clutch somehow; there's got to be "split RPM" demonstrated, so the engine is absolutely not attached to the rotor system for the practice stuff.

I believe the Eisenhower Interstate Act included language that required something like 1 mile of highway for every 5 miles be built for the purpose or capability of handling aircraft (1 straight mile for every 5 miles of road or something like that). Not sure, so I'll have to look it up. It's one of those "common knowledge" things, so it could be total bunk.

And weren't some sections of highways in the Midwest designed with a similar purpose in mind? Yeah, it's an urban legend when it comes to "there must be x stretches of y length for planes to land". I don't doubt there are stretches of highway where one could land a plane (it happens every now and then, usually a little Cessna though), but I don't know about taking off again. When you factor in specific states like dear old MI though, well, the plane probably isn't leaving the ground again.
