7A-4-1
SECTION IV. CONTINUOUS TORQUE AVAILABLE
7A-4-1. Continuous Torque Available
Continuous torque available may be obtained from figure
7A-4-1. Available torque is presented in terms of PA and
FAT.
7A-4-2. Use of Chart
The primary use of the chart is to determine available
engine torque for various combinations of PA and tempera-
ture. To determine torque available, it is necessary to know
PA and FAT. Enter the left side of the chart at known tem-
perature, move right to known pressure altitude, then down
to read torque available.
7A-4-3. Conditions.
This chart is based on a rotor speed of 100%.
7A-4-4. EAPS Installed.
Reduce the derived torque available by 1.8% however
not at transmission torque limit.
