Reference to your reply about having minimum 10% power margin available as you reduce speed while over flying the confined area may i know the Maximum Power available factor??? is it the Max Power Available for the day???? or some other value??? because while we fly at slow speed within translational lift i have never found myself close to 10% power margin figure.....its always been 40-50% less than max available in normal load conditions!
