The higher rpm settings should be used at altitudes above 20.000 ft. (see
Section 4.27). Holding power is not attainable or intended for use at high
altitude.
Cruise fuel flow increases one G PH for each 20° C below standard
temperature and decreases one G PH for each 20° C above standard
temperature.
The cruise speeds shown are at mid-cruise weight. 3740 pounds. The speed
differential for weight is 0.8 knots per 100 pounds~ faster at lesser weights
and slower at heavier weights.
The leaning procedure to establish 50° lean of peak T.l.T. is discussed in
Section 4.
