Terps requires 3.3% climb gradient or as published and far 25 requires 2.4% in the 2nd segment and 1.2% in the final segment (2 engine aircraft). Assume a 500/500/500 take off and no published climb gradient. At what altitude should you clean up and accelerate to enroute climb speed MVA/MSA/MEA or a training profile altitude 400/1500 AGL? Assume no airport analysis and AFM shows greater than 3.3% to a safe altitude.

Seems to me that your 2nd segment configuration will give the least horizontal flight path to a safe altitude since far 25 doesn't consider terrain environment.

Thanks for your responses.
