-A-<br />
A-WEIGHTED SOUND LEVEL - The sound pressure level which has been filtered or weighted to<br />
reduce the influence of low and high frequency (dBA).<br />
AC - Advisory Circular.<br />
AGL - Above Ground Level.<br />
ANCLUC - Airport Noise and Compatible Land Use Control plan; an FAA sponsored land <strong>us</strong>e<br />
compatibility planning program preceding Part 150 Airport Noise Compatibility Program.<br />
AIRCRAFT APPROACH CATEGORY - An aircraft approach category is a grouping of aircraft<br />
based on an approach speed of 1.3 V so (V so is the aircraft stall speed at the maximum certificated<br />
landing weight). V so and the maximum certificated landing weight are established for the aircraft by<br />
the certificating authority of the country of registry.<br />
(1) Category A: Speed less than 91 knots;<br />
(2) Category B: Speed 91 knots or more but less than 121 knots;<br />
(3) Category C: Speed 121 knots or more but less than 141 knots;<br />
(4) Category D: Speed 141 knots or more but less than 166 knots; and,<br />
(5) Category E: Speed 166 knots or more.<br />
AIRCRAFT MIX - The relative percentage of operations conducted at an airport by each of four<br />
classes of aircraft differentiated by gross takeoff weight and number of engines.<br />
AIR SPACE - Space above the ground in which aircraft travel; divided into corridors, routes and<br />
restricted areas.<br />
AIRPLANE DESIGN GROUP (PHYSICAL CHARACTERISTICS) - The airplane design group<br />
subdivides airplanes by wingspan. The airplane design group concept links an airport's dimensional<br />
standards to aircraft approach categories or to airplane design groups or to runway instrumentation<br />
configurations.<br />
(1) Airplane Design Group I: Wingspan up to but not including 49 feet (15 m);<br />
(2) Airplane Design Group II: Wingspan 49 feet (15 m) up to but not including 79 feet (24 m);<br />
(3) Airplane Design Group III: Wingspan 79 feet (24 m) up to but not including 118 feet (36<br />
m);<br />
(4) Airplane Design Group IV: Wingspan 118 feet (36 m) up to but not including 171 feet (52<br />
m);<br />
