UH-1h PPC Program
Version 1.0
Copyright 2002, James M. Eli

This program quickly and easily computes performance data for a U.S. Army UH-1h "Huey" helicopter in a format similar to an U.S. Army Performance Planning Card (PPC). Specifically, the program calculates the following:

Hover:

• Maximum Torque Available
• Hover Torque
• OGE Hover Torque
• Maximum Gross Weight IGE
• Maximum Gross Weight OGE
• Maximum Rate of Climb/Endurance IAS
• Maximum Range IAS

Cruise:

• Vne
• TAS
• Torque
• Fuel Flow
• Maximum Rate of Climb/Endurance IAS
• Maximum Range IAS
• Maximum Rate of Climb [fpm]

Also Includes:

• Zero Fuel Weight
• Maximum OGE Hover Height
• Density Altitude
• 10% Directional Control Margin [hover]
• Range and Endurance (time & distance) Calculations

Inputs Include:

• FAT, PA and GWt
• Skid Height
• IAS
• Calibration Factor
• Drag Area
• IR Scoop On/Off
• De-Ice On/Off
• Heater On/Off

The algorithms used in this program have been extensively tested to ensure accuracy, however it is acknowledged that errors, omissions and slight dissimilarity of data between calculated and Operator's Manual charted information exist. In all cases of discrepancies, the aircraft Operator's Manual is the final authority for resolving these disparities. Use this program at your own risk. [Program requires MathLib]
