A bit of trivia, how does 95 sec to Vrot in a 747-400 at Singapore sound ?
Sounds wrong to me. Add 4 or 5 seconds till the wheels leave the ground, thats 100 seconds. Cant see it.
Having read this thread I kept an eye on the clock out of Hong Kong yesterday.
Wind L/V
OAT 24
QNH 1020
No derate
394.6T (868k lb)
60 sec from thrust set to V2 (180kt) which is about when the wheels leave the ground
I reckon we used about 10,500ft to get to that point.
