Ratio of Maximum Continuous Thrust (or Power) at 5,000 ft , 40 deg F off standard atmosphere (OSA) to that at Take-off at Standard Sea level Conditions.

The maximum continuous thrust (or power) should be taken at an altitude of:

5000 ft OSA, Off Standard Atmosphere: (ISA + 40 deg F)

1524 m OSA, Off Standard Atmosphere: (ISA + 22.22 deg C)
