Every time we make something "automatic" we risk having an accidental operation.....imagine standing beside the float bags in the hangar when the system decides to operate for some inexplicable reason.
One would think an automatic system using water immersion switches and a manual pilot operated switch with a backup mechanically operated pilot actuated release would be the best of all things.
If we can put Rovers on Mars why can the helicopter industry not come up with a float system that covers all modes?
Likewise....why can we not come up with an AFCS that provides hands off flight right down to a hover and develop procedures to use it safely?
