Engine Out Performance
GBOWD (N337UK by end May) finally flew after a 2 year rebuild. Flight test was fine except for usual snags and a descent with the front engine only. What is the real world experience for performance versus book figures?
Its a F337G, new prop, for the CAA test flight we were 200lb under max at 4400lb, 3000 feet, 6C, rear fully feathered, rear cowl closed, gear and flaps up, extrapolation of book numbers indicates 265 feet per minute positive. The actual result was a 200 foot per minute descent.
Grateful for any real world advise. Surprising thing is that to put this aircraft on The US register doesnt require this sort of flight test, which also includes a VNE dive to ensure no boom flutter, or control handling problems!!!
