I'm looking for a formula to calculate the horizontal distance (guess it is the Ground Distance) passed during the phase of ascent (or descent), having the rate of climb in ft/min and the TAS in knots. I did not found a clear answer about this question. I think it may concern with the Climb Gradient.
Refering to the image below, I'm trying to calculate d, having:
- h = 11200 ft
- RoC = 1250 ft/min
- TAS = 75 kn
ClimbGradient = (RoC / TAS) * 6000 / 6076,12 = (1250 / 75) * 0.9874 = 16.45%
d = h / (ClimbGradient * 100) = 11200 / 1645.78711 = 6.80525 nm
Is this correct calculation? I will update this question with the correct formula in other case.
