Helicopters have a poorer unpowered flying ability than fixed-wing
Cockney Steve,
A helicopter, nicely established in autorotation, has the ability to manouvre in any direction and we can even keep the autopilot in for stability and speed datum. It can land at 60 Knots or Zero knots (especially in hands of our ex "Nam" brethren).
An airliner is committed to a touchdown at well over 100 knots.
I would suggest the helicopter fares a lot better in unpowered flight, especially at the end.
