f not driven by company policy, would you or not use always max trust?
I guess would depend on current type..... but no I wouldnt always use max thrust because current aircraft type performs so well, that it would be quite a handful at low weights and max thrust - probably 25+ degrees nose up on takeoff to prevent speed from running away - we operate from low domestic weights ( approx 1hr flights) up to max t/o international flights (10hrs +)
Also a low altitude level of would be fairly uncomfortable for pax from a max thrust takeoff at low weights.
Even with a fairly decent pad/buffer we can get a derated takeoff near the MTOW at times.
