Why are knots used in aviation over kph?
Convention, smaller numbers, everyone that it matters to knows it
I can't imagine "smaller numbers" plays any role at all.
Boeing 777 departing Dubai nearly had a major incident after takeoff

Re: Boeing 777 departing Dubai nearly had a major incident after takeoff
#52I wonder if a contributing factor is that they have local noobs flying. I know quite a few very highly experienced pilots (15+yrs at Emirates) were sent home due to the pandemic.
The only pilots in the middle east with absolute job security are the locals, and they get away with shit that would see any expat fired on the spot. You can hear stories about this from all the airlines in the region... Emirates, Qatar, Oman, etc.

#5375 feets is 22.8 meters. 234 knots is 433km/h.
Which is irrelevant, given this is about aviation where feet and knots are standardized in all but a few former Soviet block countries.

#54At least this sounds like pure human error, failure to follow pre-flight checklists, and not a Boeing engineering/mechanical problem.

#56I cannot imagine how unbelievably loud and damaging having a 777 fly 75 feet above my house would be.
Planes taking off from Boston Logan can fly as low as 300 feet over the neighboring town of Winthrop--and average about 700. I've kayaked in the area and you basically have to stop talking every few minutes when a plane takes off. Arriving flights are even a bit lower (although not as loud).
There was an episode of Cheers about this, where Carla buys a house extremely cheap and then believes it is haunted. After sleeping a night there, she finds out it’s because it is close to where planes land at Logan Airport, which calms her nerves.

#57The memo from Emirates about not setting altitude in system to airport altitude is so weird. I really hope that's not the actual message Emirates is putting out there. It doesn't matter was in system. You run your checklists and configure for your own flight / your own departure etc. Memo should be to training / recruitment - where did you find these pilots to fly a 777? So they obviously didn't pre-flight the flight…
> It doesn't matter was in system. You run your checklists and configure for your own flight / your own departure etc. I am not a pilot, but that's exactly what I thought when I read the memo too. They should be putting responsibility for the next flight on the next flight's crew, not the prior flight's crew. Train each crew to assume the plane they're prepping for their next flight is FUBAR in every way, checklist e…
Yes, assuming that the previous crew left you a 'perfect and ready to fly plane' is one hell of an assumption to make. With tiny little pieces to collect if it ends up being wrong.
Emirates has a pretty good rep but this doesn't help.

#59> suggesting [...]the previous flight crew had left the altitude setting at [...] 00000 feet Does the system really display as "00000"? That seems like an odd design choice, I'd have thought just a single "0" would be far more legible in this scenario, especially if it's on a 7-segment display. I don't think passengers would have noticed this as anything other than a regular takeoff, because ATC does request slow cli…
> I don't think passengers would have noticed this as anything other than a regular takeoff It looks like the aircraft didn't leave the runway until the runway safety area at the end. That is something any passenger looking out the window could notice. A normal takeoff has the aircraft leaving the runway well before the end.
> That is something any passenger looking out the window could notice.
I don't think so, because the departure was at 3:10AM local time (23:10Z). It would have been too dark to perceive.
Re: Boeing 777 departing Dubai nearly had a major incident after takeoff
#60Setting autopilot immediately on takeoff is very tempting because it massively reduces workload vs hand flying during a critical flight stage (high workload). So there’s a strong temptation to do this. But if you miss a few checklist items and don’t fully understand the systems, this is the result. The numbers seem to indicate they didn’t immediately recover the situation either I.e immediately switch to hand flying…
All hail engineering safety margins I guess. Hope they check out that plane, especially anything related to flap mounting and actuating as well as the flaps themselves. That's a lot of force.
