    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    No. There is no differential lift. You’re crabbing, not sideslipping. There is a crosswind technique that uses sideslipping instead of crabbing, but it isn’t generally used, especially on airliners. The aircraft will want to roll when you put in rudder to push it straight for the landing. In...

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    This sort of s**t makes me quite angry. I've flown with numerous female pilots over the years, and as a group they were just fine. Some outstanding, some not, but overall zero difference to their male counterparts. I would have no problem flying on an 'unmanned' aircraft. And all FOs have to...

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    Very true. But, any blame will stop before it attaches to the regulators or management. Pilots are convenient for that. It's back to school for you. Perpendicular means it would be at 90º, so that would need a direction of 140º or 320º. Here it's roughly 40º off so the crosswind component would...

    EK421 Unusual Route PER-DXB on 17 Feb

    That's just going around a small bit of closed airspace, and similar happens every day. The EK flight that the OP asked about took a very unusual route, that added about 1,000nm to the flight. Quite a difference.

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    None really. They would have been completely visual at that point, and the only thing they'd be looking at inside would be the ASI. Literally saying over and over...airspeed, line up, aim point, power. Depending on just what the vis was like (and it doesn't look bad), there can be a tendency to...

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    Well, I used to run a camera reasonably regularly, though mine was more a case of setting it up, and then forgetting about it. I’m not convinced that adding to the list of what you aren’t allowed to do makes the operation any safer, though it does give management another chance to deflect blame...

    EK421 Unusual Route PER-DXB on 17 Feb

    ETOPs isn’t a thing with the quads. The route they’ve chosen would be very close to 60 minutes ETOPs, though I’m not sure that the airports they’re close to are usable for a 380. The QF example for the 330 within Oz, would have been a mix of Adelaide curfew, and most likely, an APU issue. I...

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    That seems to be the way that the pilot members of pprune are tending too. Very hard, with some bank, puts the load on to one oleo. If that failed, and broke the spar, then nothing would stop the other wing just rolling the aircraft over.

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    I can imagine some real issues with getting yourself out of the seat belt, when left hanging upside down. Thinking about, it, it might be lucky that there aren’t more reported injuries, just from the fall from the seat. I can’t imagine people being able to open the lockers, but I guess items...

    Midair collision between Helicopter and CRJ (AA5342) at Washington (DCA)

    This needs context. What is the normal “on speed” pitch angle for the CRJ? Whilst 9º sounds like a lot, I’ve flown aircraft that used 12º on approach. The elevators at full deflection tells a story, but you’re not going to get much of a pitch rate at approach speed. The sink rate is somewhat...

    There’s quite a bit of history for this sort of outcome. DC-10/MD-11s had a bit of a habit…

    Delta Flight Crashes In Toronto: Plane Lands Upside Down, Wings Torn Away

    One element of the media would appear to have reached a new low… “The CNN expert guest has explained to the audience that the wings came off, because they are designed to: "They have explosive bolts...".

    Ask The Pilot

    There are entire chapters in the manuals on cold weather procedures. They are practiced in the sim exercises (predictably in the sessions just prior to northern winter for us). There are limitations on the condition of the runway, allowed contamination on the aircraft, de-icing requirements...

    QF768 Sat 12 April B737 subbed for A332

    I'll bet the issue comes back to dearest leader closing down the QF engine shop, and outsourcing the engine overhauls. When you aren't doing it yourself, you have zero priority.

    Ask The Pilot

    The cabin crew don't have to wait for the pilots before they can board. Procedures may well differ with other airlines, and airports, customs, and security can throw their own rules into the mix. Probably best if we don't discuss the doors.

    Qantas staff skipping the line at the New UberX Rank at Sydney International

    You’d be surprised. Many people seem to think the crew arrive and the aircraft can go 30 seconds later.

    All About Airport Curfews

    Curfews themselves can generally be worked around. But inflexible, rigid ones are problematic. A big problem is the interaction between destination and departure point, when they both have a curfew. That can have the effect of making only a fraction of the available open hours useful for any...
