IF it took more than :30 seconds you were heavy and if it took :45 seconds, you were very heavy.
I agree with those timings -which I've been monitoring as a pax. for some time - and if we're not airborne by 45 secs. I've decided that I'm going to start putting my head between my knees - after re-checking the emergency exit !
Looks like the Military are the only ones to check acceleration rate - interesting. makes sense, but the application Worldwide might need more than just a wish !
