Climb: don't forget speed is lower!

TOD:

120kts (2NM/min) 500 ft/min (children <12y: 300)
1NM attitude change
Speed decreasing 2NM
Approach check 2NM if needed

Compute TH with wind:

α1 = (360 + TC - WH) % 360 and sign=1
if α1 > 180: α1 = (360 + WH - TC) % 360 and sign=-1
α2 = arcsin(WS/TS sin(α1))
α3 = 180 - α1 - α2
TH = TC + sign α2
GS = sin(α3) / sin(α1) TS
