Biggest flag is flying pilot apparently selecting autopilot on immediately after takeoff. Emirates note to their crews,is even more bizarre. Like an hospital reminding Anesthesiologists to check if patients are fully knocked out before operations.
Incident still under investigation but it looks bad.
Why are knots used in aviation over kph?
From my understanding there are two advantages: - So that when kph/mph is heard a pilot knows they're referencing ground speed, whereas knots is air speed. - Pilots use latitude/longitude, and a knot is "exactly equal to 1/60th of a degree of latitude. A 1/60th of a degree of latitude is known as a minute of latitude. Therefore, a knot is equal to one minute of distance. There are 90 degrees from the equator to the p…
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 climbs (ie. slower rate of ascent) every now and then.
Pilot (piston engine, with only around 20 hours of light jet dual). As a pax on this flight, I might not have noticed much unless I was looking out the window. This seems like a fault of the crew (obviously), but probably more on the PNF (pilot not flying) than the PF (pilot flying). Article says 4 pilots were on board, but fails to mention that 2 of them (relief pilots) were likely not in the cockpit on the departur…
Maximum Flap (Placard) Speeds for 777-300 Flaps KIAS 1 255 5 235 15 215 20 200 25 190 30 180 262 is way high for 30 degrees with slats.
The 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…
TL;DR - Don't screw with the defaults (MCP) after landing, especially when it's unnecessary and when the next takeoff crew likely will not remember to set it to proper value before takeoff. I wonder if this is not a detectable condition for the flight software - maybe in some cases you want the MCP to be set to low? Otherwise autopilot could either auto correct it or issue a warning?
Why is it even possible to enter a desired altitude of 0 feet into an automatic pilot? As a layman, it’s hard for me to imagine why anyone flying a 777 would want to maintain an altitude of zero at full speed for more than a few seconds (if that).

The incident description seems incomplete. With the high takeoff speed and slow climb rate, is it possible that the main error was an incorrect flaps setting?
Takeoff configuration warning can be silenced, but is an abort before the 80 knot callout.

As one would guess, it shouldn't have been on. Insight comes from a comment in TFA:
"I’m a captain at a U.S. major airline with a lot of time in 777s. Something this doesn’t mention is the that even if ground level was set into the mode control panel, the aircraft wouldn’t have descended if it was being hand flown. That means that the flying pilot here selected the autopilot on immediately after takeoff. This is unusual at Western carriers as we like to hand fly. To me this indicates a lack of experience or confidence or both."
I also wonder about the decision to continue on after overspeeding the flaps. Takeoff flaps with full load on the 777-300ER is 15 degrees. Max airspeed with that setting is 215. They hit 260 at 175ft.
