Notes:	K7 L/D = 26:1
	Load factor is 1/cos |phi|
	Multiplier is 1/sqrt(cos |phi|)
	Vs is stall speed; Vs(0)*(multiplier)
	Vbest is best L/D; Vbest(0)*(multiplier)
	Vsink(0) is Vbest(0)/(L/D)
	Vsink is Vsink(0)*(load factor)*(multiplier)
	Radius is V^2/g tan |phi|, where g=32.17 ft/s^2
	T_3_6_0 is time for a 360^o turn and equals 2|pi|r/V(|phi|)
	descent is Vsink'*T_3_6_0
	1 mph = 1.467 ft/s; 1 ft/sec = 0.3048 m/s
