Thanks SHFG for that quick response!
If you would retract the gear for performance reasons then you should know the exact point were the obstacles are?
I mean say for ex. that after takeoff from RWY 10 the first (and most limited) obstacle are approx 11ft, 200m from the end of TODA... (11ft/(200/.3048)*100)
That will give you a climb gradient of 1.6764% NET (or 2.4764% GROSS)...
With landing gear down...Can you really clear that obstacle?
Again, i'm more than thankful for your response SHFG, and i will follow this thread with curiosity!
