OH-58c PPC Program
Version 1.0
Copyright 2001, James M. Eli

This program quickly and easily computes performance data for a U.S. Army OH-58c Kiowa (Bell 206B) helicopter in a format similar to an U.S. Army Performance Planning Card (PPC). Specifically, the program calculates the following:

Hover:

• 30 Minute Maximum Torque Available
• Continuous Torque Available
• IGE 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)

Inputs Include:

• FAT, PA and GWt
• Doors On/Off
• Skid Height
• IAS
• Drag Area
• Bleed-Air 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]
