[QUOTE="Mikecr, post: 140342, member: 1521"] [b]Re: new twist on b.c.\'s[/b] I calculate BC of a 140VLD @5Kft(std conditions & 3000ft/sec) at .706 Since I seem so close, I'll say it's BC under standard conditions & 3Kft/sec at 10,000ft is .824 If up to 50deg there BC would be .870 and @75deg = .912 It's because drag goes down with lower air density compared to the G1 curve under Std Metro conditions. There is nothing here to be surprised about really. [/QUOTE]
