"The thing that stands out here the most is the complete lack of control that the crew had over the plane. The crew was managing the computers rather than flying the aircraft."

Perhaps they are "Children of the Magenta":

... and I cannot recommend this video enough.

I am not a pilot and I have no interest in flying nor any particular interest in aviation, generally ... and I find this talk to be fascinating.

EDIT: you can jump to 3:35 where he gives a specific example of a situation where pilots need to choose between automation dependency and dropping down a level of automation. He's a really good speaker and you can tell the audience is very engaged.

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…

262 is way high for 30 degrees with slats.

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?

If the takeoff depends on it, the next takeoff crew had better remember to set it. What's more, there better be at least one checklist that requires them to set it. And they had better follow the checklists.

Standard takeoff procedures would have them rotating at a calculated airspeed and pitching for a climb target before transitioning to follow the FD. This crew’s issues went way past a pre-select mistake.

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…

Knots is used for ground speed as well I thought?

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 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…

From a top comment on the article by "Mark D":

> I’m a captain at a U.S. major airline with a lot of time in 777s. [...] Also, this is something that SHOULD have been caught by at least two separate checklists, which they obviously didn’t do.
