INTERMEDIATE FLIGHT PREPARATION WORKBOOK
The range scheduled climb speed for the 2-engine range climb is 250 KIAS below 28,000 feet,
and IMN = 0.64 at altitudes above 28,000 feet.
For 1-engine operation, the climb speed is 170 KIAS at all altitudes.
Climb performance charts are based on MCT setting for both 1 and 2-engine operation.
Performance ceilings are presented for service ceiling, cruise ceiling, and combat ceiling. These
ceilings correspond to rates of climb of 100, 300, and 500 FPM, respectively.
The range climb speed schedule will result in a somewhat longer time and a greater fuel usage
than the rate climb. The range climb schedule may be used when minimum climb fuel and time
are not required, but a longer climb range is desired.
The scheduled airspeed for the rate climb is the speed for best rate of climb. A climb scheduled
at this speed will result in the least time for the climb segment to the final altitude.
H103. FACTORS AFFECTING CLIMB PERFORMANCE
Variations in OAT from the ICAO standard day International Standard Atmosphere (ISA) have
significant affects on time, fuel, distance in climb, and performance ceilings. Temperature
corrections are provided on each performance chart.
The scheduled climb airspeeds are close approximations to the best rate of climb speeds for 1 and
2-engine operation. The results shown in the climb charts can be achieved only if the scheduled
speeds are maintained within +5 knots or +0.01 M.
Operation of Anti-Ice Systems
The operation of anti-ice systems during climb will result in decreased climb performance and
lower performance ceilings.
