Not enough rudder and too much rudder, I kinda like that! I think I'll use it...
The terms top rudder and bottom rudder or inside rudder and outside rudder are relatively new to me. has anybody used them with students? just wondering what terminology students can get their heads around easiest.
One instructor was teaching skids and slips by describing the feeling of the tail "trying to pass you on the outside" in a slip and the tail "falling inside" on a slip. Interesting, i thought. Others refer to the ball, but i don't like that. A student should be looking at his attitude in a slip, not his t & b.
As for slipping a 172 with full flaps: totally safe! Only problem is that the oscillations freak out the passengers. I avoid doing full-rudder, full flaps slips, as the placard says. I don't have a good reason for avoiding it other than the fact that is feels like those oscillations can't be good for the aircraft. But as far as performance and safety go, there's no problem.
In fact, as a student the full flap full rudder slipping turn saved me a LOT of money by allowing those "abbreviated circuits". You know, alone in the pattern, turn x-wind at 300 feet, climb on downwind, cut power abeam the threshold and slip 'er in!! You can double the number of circuits per hour!! (oh oh, here come the floggings for the poor airmanship!)
