In the Abacus / First Class Simulations package titled "Take to the Skies", with throttle fully closed ( joystick or keyboard commands ) all A/C "float" forever, and will not descend to land. With throttle fully "off" , and a 10 degree noise-up attitude, A/C maintains constant altitude and 80k airspeed, I tired increasing payload, but no effect. No response from Abacus / F.C.S. support.
My profile contains "set-up" details.
Searched this subForum but found no clues.
Suggestions will be appreciated.
