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.
Bob,
Marv's answer is precisely correct. You cannot depend on any other person's results because of the variability of construction (fast versus slow build, MKII tail, long vs short engine mount, etc.), Propeller, engine options (hi vs std compression pistons, electronic ignition, etc). The advantage of AOA devices is that the answer to most critical flight questions are displayed on one device, regardless of construction, power, weight, temperature, altitude, etc.
