I saw some serious computations a few posts behind.. If you are trying to be so accurate with the turning Radius I guess you should include the change of the gravity force (g) with altitude..
g=g’[r/(r+h)]² and then put it in the R=V²/g tanφ
g: gravity at height
g’: standard gravity 9.81m/sec
r: earth mean radius
h: height in meters
which should be somewhat negligible at lower altitudes but hey, you guys started it
just kidding! I won't mention the wind factor...
The 1%*GS*½ is the best rule of thumb ever for RATE 1 turns up to 250kts so thats what I m keeping from this thread.
