3.01-4 Operations Forecasts
Source: C&S Engineers, Inc.
An aircraft operation is a measure of activity that is defined as either a takeoff or a
landing. A takeoff and a landing are two operations. The annual general aviation
operations forecast was derived for both local and itinerant operations through the use
of an Operations - Per - Based - Aircraft (OPBA) ratio. In order to develop a
preferred OPBA method, several ratios were analyzed to find the best fit for the
Potsdam Municipal Airport. These methods are summarized as follows:
• Method 1: New York NPIAS GA Airports (772 OPBA)
• Method 2: FAA Order 5090.3C (250 OPBA)
• Method 3: One-third point between Method 1 and 2 ratios (340 OPBA)
The third method is the preferred forecast as the Airport is located within a state that
averages an OPBA higher than that suggested in FAA Order 5090.3C. In addition, a
review of the aircraft logs provided by www.FlightAware.com and the FAA TAF
indicates that existing operations levels are likely closer to the operational levels
achieved utilizing the third method. This forecast provides a conservative projection
of the Airport’s operations while allowing the sponsor to plan for steady growth over
the planning period. Historically, the Airport has experienced a local/itinerant split of
approximately 60 percent local and 40 percent itinerant operations. This split was
used in conjunction with the preferred forecast to determine the operations forecast
shown in Table 3-8.
