NGT 3002 Exam questions and answers Graded A+| 2026 Updated Atomsphere DA The PA corrected for non-standard temperature Increased DA decreases aircraft performance DA = PA + [120 * (Outside Air Temp (OAT) - Standard Temp (ISA))] We care about PA because it builds into our DA equation. Temperature In general, engine performance decreases as ambient temperature increases - High Free Air Temperature (FAT) results in increased inlet air temperature, which has an adverse effect on power output of gas turbine engines. Biggest effect felt on takeoff and initial climb. - High FAT may result in the engine being ITT limited rather than transmission or N1 limited - Total Air Temperature (TAT): This is the temperature the aircraft 'feels' due to the ram rise effect (heating of air due to compression and friction as the aircraft moves through the air). The TAT is always high
