Arlington Municipal Airport Development Plan Arlington Airport Development Plan | Page 95

The demand-based schedule provides flexibility in development, as development schedules can be
slowed or expedited according to demand at any given time over the planning period. The resultant
plan provides airport officials with a financially responsible and needs-based program. Table 3A pre-
sents the short and long term planning horizon milestones for each aircraft activity level forecasted in
Chapter Two.

AIRFIELD CAPACITY
An airport’s airfield capacity is expressed in terms of its annual service volume (ASV). ASV is a reason-
able estimate of the maximum level of aircraft operations that can be accommodated in a year without
incurring significant delay factors. As aircraft operations surpass the ASV, delay factors increase expo-
nentially. The Airport’s ASV was examined utilizing the FAA’s AC 150/5060-5, Airport Capacity and De-
lay.
FACTORS AFFECTING ANNUAL SERVICE VOLUME
This analysis takes into account specific factors about the airfield in order to calculate the airport’s
ASV. These various factors are depicted in Exhibit 3A. The following describes the input factors as
