(DASH LINE)
WANTED:
TORQUE REQUIRED FOR LEVEL FLIGHT, FUEL FLOW,
AND INDICATED AIRSPEED AT TAS = 120 KN.
KNOWN:
GROSS WEIGHT = 45,000 LB.
PRESSURE ALTITUDE = SEA LEVEL
FAT = 35
C
TRUE AIRSPEED = 120KN
METHOD 1 (SIMPLEST)
USE NEXT HIGHER TEMPERATURE (40
C)
ENTER TAS, MOVE RIGHT TO GROSS WEIGHT
MOVE DOWN READ TORQUE REQ’D = 55% (PER
ENGINE)
MOVE UP READ FUEL FLOW = 2,600 LB/HR (TOTAL)
MOVE RIGHT READ IAS = 114 KN
METHOD 2 (INTERPOLATE)
READ TORQUE REQ’D, FUEL FLOW, AND IAS AT EACH
ADJACENT TEMPERATURE THEN INTERPOLATE
BETWEEN TEMPERATURES
