In a private flying forum, how the RAF teaches flying is of less relevance to me. I think most of their aircraft differ considerably from SEPs. That said, I understand that jet powered airplanes are even slower to react to power changes than propeller powered in slow flight, so glidepath control in a jet, with power as the primary factor, must be very challenging!
Nope - 'point and power' works just as well in a PA-28 as it did in the F-4 or VC10! Glide path control in the Buccaneer was instant in the blown configuration by thrust adjustment.
We found that students who'd been taught 'point and power' gnerally soloed about an hour earlier than those taught the old way.
