Hi John,
That statement reminded me of a long forgotten question I had that was never answered. In our performance handout for the HS748, It was said that the chosen level-off height could only be 400-600 feet AAE, even though the net takeoff path general theory stuff talked about 1500 feet.
Any further input from anybody on this feathering restriction on the Dart.
