4. As angle of attack is increased, the loading on the empennage increases. This loading was the highest for nacelle angles between 75 and 60 degrees where the combination of wing/nacelle gap, airspeed, and rotor wake were the most significant. Loads were measured up to the monitoring limit during a simulated power off descent 1524 m/min (5000 fpm) at 60 degrees nacelle angle. For rates of descent less than 610 m/min (2000 fpm), the empennage loads were below the monitoring limit for all nacelle angles. In approaching rates of descent between 549 and 610 m/min (1800 and 2000 fpm) or wing stall, the loading can be felt by the pilot through increased aircraft vibration and sound level which permits him to avoid the higher load conditions.
