what I find really amazing is when pilots land at ,say YSBK, and SLAM on the brakes to take first possible taxiway - and beat their mates to the freight shed - then sit there with engines at idle for three more minutes!Why not just roll to the end (traffic permitting) then a leisurely taxi to the freight shed at IDLE, and shut down straight away ?(presuming it has cooled down the three minutes)
An engineer mate once told me also, that the Turbines are NOT working below 25in.hg, hence if you hit the circuit at say 22in.hg, and get down at 22 or below, then taxi, then the cool down time has been achieved. Is this not true ? Let's face it, when applying power for take-off, the turbines only cut in at about 2500RPM/25IN HG.
My theory has alweays been to do what the OPERATOR states that he/she wants you to do (within reason) - which is NORMALLY exactly what the POH says to do - and then IF there is a problem, then YOUR ARS# is covered!
