Rescue events with multiple victims can result in multiple flights within relatively short periods. However, on average approximately one landing/take off event per week is expected. Given the current site plan, prevailing winds and surrounding land uses, according to Heliplanners, the preliminary helicopter approach and departure flight path is expected to be a southeast/northwest alignment as shown on Figure 3-8. Helicopter Preliminary Flight Path. During emergency events, flight plans could deviate from the preliminary flightpath depending on the urgency of the situation. Further, other factors could affect flightpath layout at the actual time of heliport design which would occur during detailed Phase 2 site planning. Helicopters would descend to and climb from the heliport on different vertical profiles that may vary according to the pilot, weather, helicopter loading characteristics, etc. In general, for noise analysis purposes, default vertical flight profiles are used in computer noise modeling conducted for the Project.
