The test program will assume that the solo airplane is always a solo airplane. That is, it is never rotated to the Diamond or Delta position. The test will be performed using a flight-by-flight loading spectrum based on actual flight data and composed of show, practice, and cross-country flights. The individual flight spectra and the overall mission spectrum are defined in this report. (Author) 收起
