Another Sloppy report!
So, Here we have armchair experts PAYED to investigate and they dont even come up with a proper ICAO standard report .
Namely the fact all the V1 V2 and Vr and Vref was WRONG with a factor close to 1.3 or 1.2.
On the 737 one ton equals ca 1 knot, so if I take off with speeds for a a 10 to lighter aircraft I would use Vspeeds that are ca 10kts to slow.
I would ask you 777 drivers to do a quick calculation for the two scenario we have here : 1 the calculated one and 2 the actual one.
Also C\G is wrong as the 777- 200ER Center Tank is more forward.
Boeing and the Airline got of hook this time as I can not think of how this could have gone the other way, Gimli Glider style.
Standing by to be corrected.
