Hi All,
My first post on this forum.
I would like to throw a theory at you all. Relatively low percentage chance of happening though.
I'm not knowledged in the intricacies of the MD flight management computer, but are the final V1-Vr-V2 speeds programmed into the FMC at the gate? Reason I say this is as the aircraft returned to the gate less taxi fuel used, would the used up fuel, after taxi to Rwy36, return to gate, then more used up fuel again to Rwy 36 have affected the V numbers already programmed into the FMC?
Did the pilot order more fuel at the remote gate to cover the loss of the taxi out/in/out?
If not, would the 30 minutes or so of fuel used in the taxi out/in/out change the actual Vr speed if the crew did not reprogram the V speeds? On top of this, changes in temperature, air density etc due to the 1 hour delay originally from the gate may change the V speeds?
Bad V speeds may have caused the early rotation and over-rotation due to passing of V1 in haste to get airborne, then onset of left wing stall.
Cheers.
