Flight-Test Data on the Static Fore-and-Aft Stability of Various German Airplanes
"The static longitudinal stability of an airplane with locked elevator is usually determined by analysis and model tests. The present report proposes to supply the results of such measurements. The method consisted of recording the dynamic pressure versus elevator displacement at different center-of-gravity positions in unaccelerated flight" (p. 1).
