Would the Spitfire count?
Would a flight in the Spitfire count for renewal? It is a single engine piston...
My FAA certificate is good for up to 12,500 pounds, high performance and complex, night, controlled VFR, and IFR single or multi. All I got credit for from the Germans is day VFR up to 2,000kg.
I don't think the finance minister would approve of renewal in the Spitfire, but I can dream.
I think my first choice would be the Tiger Moth, Firefly, Bulldog, Chipmunk. Not quite sure why that order, just a feeling. Any other candidates?
