re. touch and go....
This is something that I thought everyone would do basicly the same, seeing as how we all spent so much time doing touch&gos when training...
I have always been taught :
1. Flare & Touchdown, center of runway, keep straight... Im Happy..
2. Carb heat cold, Flaps up to takeoff setting, check still straight...
3. Gradually re-apply power, keep straight...
4. Check instruments & when at rotate airspeed off you go again...
I am somewhat surprised to hear that some are being taught to get back in the air with full flap, this seems dangerous... but then maybe I am mis-understanding what you are saying.
Regards, SD.
