How does the presence of obstacles at the departure track affect the thrust reduction height? Could you give me an example please?
Do all aircraft execute thrust reduction at a specific height? Or it depends on performance of aircraft, weight, weather conditions or departure procedure?
Q1: it doesn't.
Q2: thrust reduction heightis an airline SOP
the two answers above refer to a routine departure with all engines operating. If you've got an engine failure prior to thrust reduction height you continue with take-off thrust until the flaps are retracted starting at "engine out acceleration altitude" (or the AFM limitation of 10 minutes on our 737.. if you remember)
As a side note, what you call thrust reduction height often becomes a "thrust increase height" as we derate so much that our take off thrust is lower than climb thrust
