line up allowance JAA A320
very well explained in grips with performance,
our laptop calculates t/o performance based on a 90 line up allowance
(i understand there is a standard one to correct for tora and asda and each operator must cater for their own, obviously in excess not in defect).
my inquiry
what is the purpose of the yellow line on line up?
i always continue straight ahead deviating from the yellow line as i did on the cessna 152.
thanks for listening
