the angle of bank depends on the TAS and the radius of turn
Ahh not really true.
The "radius" of the turn will depend and the angle of bank, the "g" pulled during the turn and the KIAS/TAS being flown. The "rate" of the turn will also be effected by the same factors
Also remember that the stall speed can be effected. Calculated as such--the stall speed x the square root of the load factor. The aircraft will always stall at the same KIAS at 1 G and level.
ie 79kts (normal stall speed clean) 4 G square root is 2, therefore stall speed is now 158Kias.
Turning at 90 AOB you will have to use the fuselage to generate lift either that or pull infinate "G" which is impossible due to power and stall speeds. Not to mention cannot build it
