U.S.
ENROUTE CLIMB
Normal enroute climbs are performed with flaps up, at full throttle and
75 to 85 KIAS for the best combination of performance, visibility and
engine cooling. The mixture should be full rich during climb at altitudes
up to 3000 feet pressure altitude. Above 3000 feet pressure altitude,
the mixture can be leaned as needed for increased power or to provide
smoother engine operation.
If it is necessary to climb more rapidly to clear mountains or reach
favorable winds at higher altitudes, the best rate of climb speed should
be used with Maximum Continuous Power (MCP). This speed is 74
KIAS at sea level, decreasing to 72 KIAS at 10,000 feet.
If an obstruction dictates the use of a steep climb angle, the best angle
of climb speed should be used with flaps UP and MCP. This speed is 62
KIAS at sea level, increasing to 67 KIAS at 10,000 feet. This type of
climb should be of the minimum duration and engine temperatures
should be carefully monitored due to the low climb speed.
