PT6A.....was told in my 737 yonks ago to line up and wait at
Madras behind a departing LH 747. Saw an aircraft on TCAS
8 miles out and calculated there'd be enough room for my 2
minutes and enough separation from the landing bloke. I did
think ATC knew this as he told IA to slow down to minimum.
Just as the LH got airborne I was told "cleared for IMMEDIATE
takeoff." I jumped in and said "NEGATIVE...require two mins
behind Luftahansa for wake turbulence separation." The ATC
scrote screamed his bloody head off saying an Indian Airlines
was six miles from touchdown. I countered again and said I
will wait more 1 minute before accepting a TO clearance. All
ended when I shoved the throttles at 2min 10sec after the LH
started rolling.
Huge stink on CTL afterwards but suffice to say I never ever
accepted a lineup anywhere in India again if anyone was on
final within 10 miles and I was to depart behind a heavy.
