Europe uses a system of airport and airway slots to avoid delays. If
your airway or airport slot has expired, a new one must be
renegotiated. Once you taxi in Europe, you takeoff as soon as you get
to the runway. So to avoid delays at the end of the runway, one must
call pre-start for clearance and to permit ATC coordination.

Not just for turbines, also for piston...


What's the reasoning behind that, if any?
