SPEED FOR MAXIMUM ENDURANCE
KNOWN:
SPEED FOR MAXIMUM RANGE
GROSS WEIGHT = 45,000 LB.
MAX. SPEED AT CONTINUOUS TORQUE RATING
PRESSURE ALTITUDE = SEA LEVEL
FAT = 35_C
ESTIMATED AIRSPEED LIMIT WITH CRUISE GUIDE
TRUE AIRSPEED = 120KN
INDICATOR (CGI) OPERATIVE
METHOD 1 (SIMPLEST)
KNOWN:
USE NEXT HIGHER TEMPERATURE (40_C)
GROSS WEIGHT = 50,000 LB.
ENTER TAS, MOVE RIGHT TO GROSS WEIGHT
MOVE DOWN READ TORQUE REQ’D = 55% (PER

FAT = 30_C
MOVE UP READ FUEL FLOW = 2,600 LB/HR (TOTAL)
METHOD:
MOVE RIGHT READ IAS = 114 KN
READ SPEEDS WHERE GROSS WEIGHT LINE
METHOD 2 (INTERPOLATE)
READ TORQUE REQ’D, FUEL FLOW, AND IAS AT EACH
