As a bit of a plane spotter geek, I took a look at the Sea Fury pilots notes and the emergency procedure for the undercarriage looks horribly complicated and not exactly what you want to be faffing with while maintaining 130kts and judging your approach.
Looking at the RPM control lever, it has an auto setting with a manual over-ride for high rpm. It doesn't mention any actions to do with the rpm with an engine failure, so I would imagine the prop goes high rpm with no options to manually select low to extend the glide. Any ideas? Now that we are allowed to play with the wobbly props on Tutors during a PFL, it does make a difference. Surely it would also make a huge difference to the glide of a big piston too?
