Total Energy Compensation Explained: Part II
by Bill Elliott •
We left off last week with the conclusion that for accurate total energy compensation a known coefficient of pressure of -1 is required somewhere on the aircraft. This weeks post will cover how to utilize that conclusion to give accurate total energy …
Total Energy Compensation Explained: Part I
by Bill Elliott •
Most every pilot will tell you that a good total energy (TE) compensated variometer is essential for soaring flight. But how and why does it work? Total energy compensation, in the form commonly used in sailplanes today (capacity bottle and bent probe…
