Objective and Outline!
 Review briefly the rationale underlying
the geometric design specifications for
airfields
 Outline:
-  ICAO and FAA Reference Codes
-  Practical observations
-  Principal documents
-  Examples of specifications and
rationale

Airfield Design Specifications!
  The two most-commonly used sources of
geometric specifications for airfield design are:
1. ICAO Annex 14 (“Aerodromes”) [latest 2009,
5th Edition] and many associated documents,
esp. Aerodrome Design Manual, Parts 1 + 2
2.  FAA Advisory Circular 150/5300-13 (“Airport
Design”) [latest: Sept. 2012]
  FAA updates of specifications are usually
developed earlier than updates to ICAO Annex
14 (e.g., Group VI standards)
  Runway length requirements: AC 150/5325-4B

Remarks: ICAO and FAA Airport Reference Codes
!
 Practically all major commercial airports belong
to the ICAO Code #4 class
 In practice, Outer Main Gear Wheel Span (ICAO)
is “dominated” by Wing Span
 Similarly, Tail Height (FAA) is “dominated” by
Wing Span
 ICAO Code Letters A-F Wing Spans correspond
exactly to FAA Airplane Design Groups I-VI
wingspans
 Most geometric specifications for airports are
determined by the Wing Span of the most
demanding aircraft
