Spitfire Test

This short video is of the Mk. 26 during undercarriage test, both retraction and extension. It is driven by an electric screwjack. When the system is armed and the lever pulled to remove the pin, this triggers different micro switches to sequence the operation of the leg and also give warning lights in the cockpit as to the situation with the leg. Locked up or down or in transition. or not locked. Dave
