High Altitude Deterioration
Fuel re-adjustment in percentage for altitude
NOTE:
(1) The percentages listed above are for standard machines.
(2) These values at each altitude range indicate the percentage of the horsepower obtained at the sea level after fuel re-adjustment against rated flywheel horsepower. 100 percent means that no fuel re-adjustment is required.
(3) *: With automatic altitude deration.
