6.2.2 Runway Configuration:
Runway configuration refers to the number and relative orientations of one or more
runways on an airfield. It affects the operational efficiency and capacity of an airfield.
Airport runways must be sited, oriented, and configured to provide for safe and efficient
use of the airport under different conditions. The runway configuration is mainly affected
by the local weather conditions, the aircraft performance requirements, and the type and
amount of air traffic to be serviced.
- Assumptions and Design Conditions:
a- Annual operations: The expected annual operations at Al-Auja Airport was shown
in Table 5-21.b- Flying rules and weather conditions: Visual flight rules (VFR) for arriving and
departing aircraft are applied to flying conditions when the ceiling at the airport is
at least 1000 ft and visibility is at least 3 mi. If either or both criteria are not met,
then the instrument flight rules (IFR) are in effect. Of course, all airports have a
period when conditions are such that IFR rules apply. So, consider IFR.c- The runway configuration and the preliminary estimations of hourly and
annual capacities are certified by the FAA (AC 150/5060- 5 ), presented in Table
12 - 9.
