In­ter­ac­tive flight man­ual for pis­ton-en­gined air­craft

Pilot - - NOTES -

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
