However what was even more interesting perhaps is the JAR standard for spin recovery: The standard procedure to recover from a spin is as follows:Point (3) is of special interest. It would appear a reasonable conclusion that what Chris related in his posting yesterday, at least in respect of control column input was exactly in line with the JAR requirement. I'm not sure where this leaves us, other than that I'm somewhat relieved that I'm not scheduled for spin checks this weekend ;-) Regards, Terry PS I also found the following phrase in the JAR papers somewhat curious, but quite comforting (perhaps): g) It must be impossible to obtain uncontrollable spins with anyDon't you feel better for knowing that ...........? |
