How to estimate takeoff shift(A320)?
Accordingly to our SOP we should enter the takeoff shift distance if takeoff is to be from an intersection. If a runway has a displaced threshold but we take off from the beginning of the runway (LEBL 07L) what distance should we enter as takeoff shift: nothing or distance between the beginning of the runway and displaced runway threshold??
Takeoff shift value must be positive but what should we use as reference point? a displaced runway threshold or the beginning of the runway?
