Climb angle speed
WBS,
Regarding climb angle speed, you remember the basic power curve? The tangent to the power required curve from the origin of the power available line gives the best climb angle speed. What this means is that:
1. The best climb angle is irrelevent when power available is more than power required. i.e. the best speed will be zero.
2. When power available is lesser, then the best speed will actually depend upon how much lower the power available is- lower the power avbl, higher the best climb angle speed
