Code option= 1 - for defining condition with SHP
option = 2 - for defining condition with thrust
option = 3 - for reverse thrust calculation
Shaft horsepower or thrust per propeller depending on option selected in 1
option = 1 - SHP
option = 2 - Thrust
option = 3 - SHP for zero velocity, full throttle setting
Altitude in feet
For options 1 and 2, forward flight calculations, code
4. Velocity, knots true airspeed
5. Temperature, O F - code 0. for standard day

7. Increment of tipspeed
8. Number of tipspeeds
9 fPS
9. Distance of field point at which noise is to be computed. Directivity for
peak noise is automatically used. The noise calculation should be made
for take-off conditions only; code = 0. when no noise calculation is to be
made.
10. Code = 1. for computing the tipspeed corresponding to
option should be used for take-off conditions only.
50% stall. The
11. Code = 1. if cost and weight are to be computed. This option must be used
with a take-off condition.
For option 3, reverse thrust calculation, code
4. Landing touch down speed, knots true airspeed
