Since our
Lancairs have propellers (we produce power), our max L/D gives us best glide, best
rate of climb and max range. The
combination of best glide, best angle of climb, and max endurance occur at L/D
max for jets (thrust).

Don't
forget that best angle of climb is a function of AOA, and happens at
the angle of attack that matches L/D max. If you don't have an AOA
indicator
you can find L/D max in a more relaxed setting by finding your best engine out
glide. Remember also that the airspeeds that at which these AOAs occur
will
vary with wing loading, so will be faster when heavily loaded, slower when
light. (L/D max gives 3 critical flight regimes... engine out glide, best
angle of climb, and max endurance.) Install and calibrate an AOA indicator to
your airplane and it will tell you exactly where L/D max is every time,
regardless of wing loading... just pull back on the stick til you get the L/D
max "picture" and you're golden.
