Setup

target cruise speed 20 m/s 65 ft/s
target bank angle 45 deg 45 deg
stall [depend on cruise]
climb gradient cont. climb over course? 0.1

takeoff field length: estimate around 375 ft from graphic below → fix at 300ft for the code

CD_i from AVL, incl trim drag,

find drag with some speed, compare with T
