What does that mean? If Biggles uses PnP or 'power for flightpath' he will have to use the other control to maintain one element of balance. If he pitches down to increase speed, he will have to add power to maintain flightpath. Conversely, if he uses power to increase speed, he will have to adjust pitch (AoA) to maintain flightpath. The order in which he does this is largely irrelevant and we should actually be teaching that the controls be used in unison.
Totally agree. Either option is just a different mindset.

Cats Five,

Can you please just answer the question;

Why is it that if the amount of lift remains the same and the weight remains the same but drag is increased then the aircraft will stay in the air for less time?

Think glider or B747 it does not matter more drag means less time in the air!!

Regards,

DFC
