SECTION II. EMERGENCY TORQUE AVAILABLE
7-2-1. Emergency Torque Available.
Single engine emergency torque available may be ob-
tained from figure 7-2-1. Available torque is presented
in terms of PA and FAT.
7-2-2. 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.
7-2-3. Conditions.
The chart is based on a rotor speed of 100%.
7-2-4. EAPS Installed.
Reduce the derived torque available by 2.0% however
not at transmission torque limit.
