Available torque is presentedin terms of PA and FAT.7-2-2. Use of Chart.The primary use of the chart is to determine availableengine torque for various combinations of PA and tem-perature. To determine torque available, it is necessaryto know PA, and FAT. Enter the left side of the chart atknown 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.
