Description: These charts (Ref. Figure 5−4 thru Figure 5−16) show the rate of
climb vs pressure altitude at maximum continuous OEI power at gross weights
ranging from 3500 LB to 6250 LB at the best rate of climb speed.
NOTE
: These charts based on an electrical load of 30%, heater off, and air-conditioning
off.
Use of Chart: The following example explains the correct use of the chart in
Figure 5−4.
Use of Charts: Use the chart as illustrated by the example below.
Example :
Wanted: Rate of climb
Known: Pressure altitude = 4000 feet
Known: Outside air temperature = 0
°
C
Method: Enter the left side of chart (Ref. Figure 5−4) at the known pressure
altitude of 4000 feet. Move to the right to the 0
°
C temperature curve
and then directly down to read rate of climb of approximately 1590
feet per minute.
