maximum continuous MGT or 820°C or the maximum continuous EGT which

is found on the OAT vs EGT limits placard.

4.6.1.3 To determine rate of climb at a particular OAT and pressure

altitude:

1. Determine which chart is to be utilized

2. Convert the pressure altitude and OAT to density altitude utilizing the

Density Altitude chart (Figure 4-13)

3. Enter the appropriate climb chart at the desired density altitude and

proceed horizontally to the planned gross weight.

4. At the planned gross weight proceed vertically down to the lower axis

and read the predicted rate of climb.

4.7 Landing Distance

The Landing Distance charts provide the landing distances required to clear

a 50 foot obstacle for all outside air temperatures, pressure altitudes and

gross weights.

4.8 Height Velocity

The HV diagram represents the factors of airspeed and height above ground,

which represent a critical area of helicopter operation during takeoff and

landing. Refer to, Figure 4.14, HV Diagram. The HV Diagram was

developed using a smooth, level, firm surface. The HV diagram is only valid

when the WAT limitations (Figure 1-4) are not exceeded.

Prior to takeoffs made in accordance with the H-V diagram proceed as

follows:

Refer to Weight-Altitude-Temperature (WAT) Chart, Figure 1-4, for gross

weight limit.

Determine the wind direction and speed. Downwind takeoffs are not

recommended because published takeoff distances will not be achieved.
