The danger here is that we are talking theory where
we may start to confuse pilots. It is harder to stall with 60 degrees of bank. Gliders like the K13, by design run out of elevator in straight and level flight. They are difficult when flown with heavy pilots to develop more than a mushing stall in sraight and level flight. Put light -- bottom weigh pilots in and they become a different glider. The Puchacz on the other hand has plenty of rear elevator even when banked, quite steeply. There can be some dangerous assumptions that gliders will not spin. The pilot must know the limitations and characteristics of the glider he/she is flying. This can only be achieved by carefully experimenting with different configurations and different flight situations. Gliders with reputations that they will not spin, can catch pilots out who load them wrongly, fly them badly or worse combine both. Dave Martin Get some empirical experience. Hop in a G-103, circle at 60deg bank and bring the stick back to the stop. If properly rigged, it will not stall. Do the same in straight and level flight. It will stall, in a mushy sort of way depending on loading. Also, in a G-103, you will get more elevator authority in tight turns by moving the trim forward. This is not true of all gliders, but clearly in a 60deg bank, the G-103 is stall proof by design. Frank Whiteley |
