Direct specific excess power contours from level acceleration flight test
The direct specific excess power values computed by the display were then plotted versus their respective airspeeds and Mach numbers for the piper Saratoga and the X-30 respectively.
A simulated light test was also conducted to investigate the feasibility of using the display to generate data for optimal trajectories for the X-30 with the aim of traversing from one specific excess power contour to the other to gain altitude and with no energy losses.
The utility of the real-time energy management display was evaluated for generating direct specific excess power contours from level performance light test and for achieving lights on constant [P.
The flight simulation results proved the display to be successful in obtaining direct specific excess power contours from level acceleration light tests and in providing guidance for flights along constant specific excess power contours at low airspeeds.
