I think its a good idea to give a student or transitioning pilot a go around without being able to retract flaps.
We are not talking about a PPL transitioning from a 150 to a retractable complex single we are talking about jumping from one simple single to another!
You would think we were talking about students
Any PPL should be perfectly capable of flying to 3000 feet and checking out the behaviour differences with full flap or part flap on their own.
So you really need an instructor to change from a PA28 to a C150? i think not. These are PPLs not students!
Really stinks of flying clubs out to make money
