Back in August I did a two day refresher (having been on furlough) / OPC/ LOE sim event. It included looking at high-altitude stalls. I’m new to type (first OPC). The 737 is 3 times heavier than previous type and it impressed me how long the recovery took. Contrast that with a check flight in a glider (DG500) a couple of weeks later, in which the stall was sharp, control forces at low speed very low and recovery takes a few seconds. Stick and rudder flying certainly helps keep those motor skills alive but with obvious caveats.
Having said that, the previous poster mentioned the effect of G. When I returned to gliding after years of airline flying, on the first flight as we were just about to enter into a spin and the G reduced I thought ‘ooh, i don’t like this!’ - and I have hundreds of hours of gliding, gliding towing and skydiving-flying. Soon get used to it again but it is upsetting if unused to it.
