Interactive flight manual for piston-engined aircraft
Alfred Scott, founder of Sequoia Aircraft which developed the home/ kitbuilt version of Stelio Frati’s classic Falco, has launched Sequoia Benchmark, a computer program that enables you to create an interactive flight manual for any piston-engine aircraft with a constant-speed propeller, single or multi-engined.
“This project is 26 years in the making, and it’s a unique program for performance flight testing and analysis,” Alfred (an old friend of Pilot) tells us. “It is based on a method of performance flight testing and analysis first developed by Boeing during World War II to create accurate performance flight manuals for the B-17 and B-29 bombers. It was a revolution in technology, and it provided the ability to create fuel efficiency charts for a wide range of aircraft weights, payload and number of operational engines at any altitude or temperature. This method is now used by all aircraft companies [and] requires accurate data on the engine power, propeller characteristics, aircraft specifications and flight performance.
Sequoia Benchmark is available free of charge from the Mac App store. For more details visit: seqair.com/benchmark/ index.html
