RE: wingloading in a turn or loop?
To help with the memory, in a level, i.e. not climbing or decending 60 deg bank turn, the airplane will "feel" 2 g's, or twice its weight. However, as the bank angle approaches 90 deg of bank (for a non-climbing or decending turn), the g's approach infinity, as it would be impossible to attain any portion of the lift vector to counter gravity if it were aligned perfectly with the horizon. Hope this helps..
