Cleared for Takeoff
Let's suppose I wanted to test a glider to determine it's glide ratio (or to see if the published glide ratio is accurate).
Given that I don't know how to do this. The following equipment is on board:
Dynon 100 EFIS
Dynon 120 EMS
Garmin 496
TruTrack 2 axis AP
What ways do you know of that would let me get close in a couple of tests - not a dozen rigorously done in ideal weather but a couple that were done with care. Precision important but not vital.
One way is to start at an altitude, maintain a guess at and carefully maintain the best glide speed, and measure the time to another altitude. Gives you A & C, Solve for B.
Other ways of measuring A&B would require one to make good estimates on wind, I'd think. Ideas?
