I don't see anything weird about that runway on google maps though?

The PAPI is working on that runway right? If they were flying VFR then they must have been flying it by hand there. No US airline flies anything that big under VFR, you sure they didn't say VMC prevailed at the time of the accident?

Depends on the reason for the crash and if they were injured. The pilots that flew the gimli glider for example continued to fly for air canada including on the same plane. The pilots involved with the BA 777 crash flew again but one seems to have left flying due to PTSD.

I can't think of any major fuckups by flight crews that left them alive and able to conceivably fly again off the top of my head.

The story of the BA 777 pilot is
confusing. Like he was suspended,
then took a voluntary layoff, then wrote a book critical of BA, then... was rehired?

I think it goes something like he was on paid leave for a while following the wreck for obvious reasons, then when he returned to duty he didn't want to do it due to PTSD flashbacks and took a voluntary layoff. He then wrote a book about how terrible BA's treatment of the situation (see PTSD) but eventually wanted to fly again and asked to go back (insert therapy or whatever in the intervening time).

I think that's what they're trying to say.

There is also a reason that commercial pilots (or at least passenger transport) are generally required to use navigational aids like the glide slope if they're available. While it's not impossible to safely complete a flight without them, it is less safe. I'm also mystified at the low level of importance people are placing on the Pilot Flying's level of familiarity with the aircraft. He certainly SHOULD have been able to land safely, but the low familiarity means every step of the approach was harder and took longer than it otherwise would have, and if you don't think that was a major factor in this accident then I don't know what to tell you.

Remember that "stupid pilot did a stupid thing" is never an acceptable explanation for an accident, the system should be as resist as possible to single failures, especially human ones. In this particular case, the Pilot Monitoring should have been calling for a go around long before the approach was unrecoverable. Even Air France 447, a great example of lovely airmanship bringing down an airplane, is more correctly understood as a flight control system design defect as it trained pilots not to fly the aircraft (rather operating the flight control system in normal law).

Bonus Edit: Even Pinnacle Airlines Flight 3701, which was an egregious case of unprofessional behavior, may not have occurred if the pilots had received adequate training in the high-altitude performance of their aircraft so they knew exactly how stupidly dangerous what they were about to attempt is. In short, you can call out the pilots for doing something stupid, but you need to call out their airline for not making sure they knew how stupid it was.

The pilots of Pinnacle 3701 didn't know how airplanes worked full stop.

What exactly are you saying should be the standard for a VFR approach? Should all aircraft have a HUD with a TVI and a giant 3 degree line like a 787? This aircrew probably would have flown that TVI indicator right into the loving seawall.

edit: by tvi I meant total velocity vector indicator but what is it actually called on a Boeing?

edit2: flight path indicator

If you watch the video, the nose seems like it's angled up more than I've usually seen. It was one of the first things I noticed, and I'm assuming with idle throttles, it's why the plane stalled.

The plane being at too high of a pitch compared to the flight path is the definition of a stall.

Raked wingtips would extend the wingspan out past normal limits for clearance at airports. They would have to use different gates to avoid any conflict with aircraft next to them. The Navy doesn't have to worry about gate space so raked wingtips it is.

Also, raked wingtips are inefficient for short trips so intercontinental and aircraft that will loiter for forever will want them while shorter ranged 737 variants will not.

Is this because short range flights spend a larger portion climbing and descending than long ranged flights?

Yes. Its a trade off between climb performance (winglets) and drag (raked wingtips).

iyaayas01 posted:

He's not. X-47 is autonomous-ish, the human is just in the loop to tell it what to do, the plane more or less flies itself as far as direct control inputs and the like. It's not like Preds/Reapers where the human is hand flying the thing the whole time (or at least when the autopilot-ish function isn't engaged).

The LSO is in charge of the deck though, hes the one that is controlling the landing of the manned air craft, telling them to add/decrease power and when to go around. I'm wondering if this drone can be controlled in the same tight manner and if its not how they could possibly integrate that with carrier ops.

But the aft battery bay is between doors 2 and 3 and the fire was like right above door 4?

The burn marks are where the FA rest area is...

a large part of that trust comes from the fact that they never release or confirm names of anyone involved in an accident or ever release CVR audio from aircraft accidents.

Might want to tell them to take this offline then because you can get CVR transcripts, recordings and extensive crew biographies in every incident docket.

There's at least one still flying around in the US, although I have no idea how the owners can afford to keep running it. Since even the later Jetstar models are running 1970's vintage engines, they'll typically burn through a bit more than twice as much fuel for a given flight as a modern Learjet, and I'm sure parts are getting to be pretty expensive as well.

Due to a quirk in how Lockheed designed the pressurization system in the Jetstar, it also requires at least one engine to remain at a pretty high power setting through descent, since the engines can't produce enough bleed air to keep the cabin pressurized at idle.

Is that why it has a speed brake?
