This report documents the methodology used in developing the helicopter departure profiles presented in Helicopter Physical and Performance Data DOT/FAA/RD-90/3. Each step involved in creating the profiles is examined. In particular, the Helicopter Departure Profile (HEDPRO) program is described in detail. This program converts helicopter performance data and departure procedures into departure profile data. The first step in developing profiles was to identify the departure procedures recommended by the manufacturers. Additionally, a safe confined area departure procedure needed to be developed. Next, climb and acceleration performance data specific to each helicopter and atmospheric condition was generated. This required extensive data to be collected for each helicopter. This data was then used in the Helicopter Sizing and Performance Computer Program (HESCOMP) developed by NASA/Boeing to compute helicopter performance data. The last two steps were to compute and graph the profiles. HEDPRO was developed specifically for this project to compute the departure paths by determining the height/distance points of the path from the helipad. These points were then graphed to develop the final product. This methodology is described in sufficient detail so as to be a valuable aid should other helicopter departure profiles need to be determined.
