How many airports are in the NPIAS and what three types are included? - ANSWER 3,380 airports; 1) commercial service, 2) reliever, 3) select GA What are the three defining characteristics of commercial service airports? - ANSWER 1) open to the public 2) receive scheduled passenger service 3) 2,500 or more enplaned passenger per year What type of airport has commercial service and over 10,000 annual enplanements? - ANSWER Primary airport Primary airports are split into 4 categories, what are they and how are they defined? - ANSWER Large Hub (1% of all US annual enplanements); Medium Hub (0.25% to 1%); Small Hub (0.05-0.25%); Non-Hub (10,000 to 0.05%) How many enplanements characterize a non-primary commercial service airport? - ANSWER between 2,500 and 10,000 enplanements per year What characterizes a reliever airport? - ANSWER 1) open to the public; 2) 100 or more based aircraft or 25,000 annual operations General aviation airports can be included in the NPIAS under what circumstances? - ANSWER If they have at least 10 locally based aircraft and are at least 20 miles from a NPIAS airport What plan provides guidelines for an airport's capital development over a 20-year timeframe? - ANSWER Master Plan What is the set of drawings that shows the airport's long-term development, updated in accordance with grant assurance number 29? - ANSWER Airport Layout Plans Runway design standards are based on what three primary factors? - ANSWER 1) airplane design group (wingspan); 2) aircraft approach category (approach speed); 3) approach visibility minimums Taxiway and taxilane design standards are based on what primary factor? - ANSWER airplane design group (wingspan) How is airplane design group determined and categorized? - ANSWER Based on the aircraft's wingspan and tail height whichever is most restrictive; 6 categories, I thru VI, where I is the smallest/shortest and VI is the largest/tallest How is aircraft approach category determined and categorized? - ANSWER Based on aircraft approach speed; 5 categories, A thru E, where A is the slowest and E is the fastest What are the 6 categories of airplane design group? - ANSWER I (tail height 20', wingspan 49'); II (tail height 20 - 30', wingspan 49 - 79'); III (tail height 30 - 45'), wingspan 79-118'); IV (tail height 45 - 60', wingspan 118 - 171'); V (tail height 60 - 66', wingspan 171 - 214'); VI (tail height 66 - 80', wingspan 214 - 262') What are the 5 aircraft approach categories and the criteria for each category? - ANSWER A (91 knots); B (91 - 121 knots); C (121 - 141 knots); D (141 - 166 knots); E (166 knots) When is a cross-runway recommended? - ANSWER When a runway orientation provides less than 95% wind coverage for any aircraft forecasted to use the airport What are some of the factors affecting the location and orientation of runways? - ANSWER wind, available airspace, environmental factors, obstructions, topography, ATCT visibility, wildlife hazards To ensure water run-off, what is the normal grade of a runway and runway shoulder? - ANSWER 1 - 1.5% cross-section grade for the runway and 1.5 - 5% for the runway shoulder What is the purpose of a runway shoulder? - ANSWER resist runway erosion, passage of vehicles and surface for aircraft that veer off the runway How is runway width determined and what is the range of standard widths? - ANSWER ARC and approach visibility minimums; 60 - 200' What is the range of widths for a runway safety area (RSA)? - ANSWER 120 - 150' What is the term for an area formed by imaginary lines connecting the visibility points of two different runways? - ANSWER Runway Visibility Zones (RVZ) What is the term for the beginning or end of the full-strength runway pavement available for takeoff and landing? - ANSWER Runway threshold When a runway threshold is not located at the start of the full-strength pavement what is it called and why would this occur? - ANSWER Displaced threshold; it is used to identify the first point for landing aircraft to avoid an airspace obstruction, to mitigate environmental considerations, or to lengthen an RSA or OFA What use is the portion of runway behind a displaced threshold? - ANSWER It can be used for takeoffs in either direction, and landing from the opposite direction. Taxiways are designed to allow aircraft taxi at what speed? - ANSWER 20mph How are taxiway widths determined and what is the standard range of widths? - ANSWER Based on wingspan and wingtip clearance (ARC); 25 - 100'
