Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

The worst case scenario means here a Rotol propeller and CoG behind the aft limit for that configuration, like in the NACA tested Spitfire.

Fixed Pitch Wooden Airscrew

Longitudinally, the aircraft is stable with centre of gravity forward, but is unstable with centre of gravity normal and aft with engine 'OFF' and 'ON'. Longitudinal stability records are attached.
