Thanks Crowsnest,
In the PPSC notes I have on performance it seems to state that the AOA should remain constant once you are climbing at a constant IAS. I have printed the paragraph below but now I believe that it's not correct.
"Climbing at a constant IAS will cause the TAS and Mach number to increase. Although a constant angle of attack is maintained, the climb gradient and rate of climb will both decrease because of the decreasing excess of power available over power required. After changing to a constant Mach number, both the IAS and TAS will gradually decrease. Because of this the angle of attack must be increased. Consequently, despite the decreasing power available the climb gradient increases. Therefore, in a normal atmosphere, at the crossover altitude the climb gradient changes from one that is decreasing to one that is increasing."
