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