Section 5. Runway Selection
3-5-1. SELECTION
a. Except where a "runway use" program is in effect, use the runway
most nearly aligned with the wind when 5 knots or more or the "calm wind"
runway when less than 5 knots (set tetrahedron accordingly) unless use of
another runway:
NOTE-
1. If a pilot prefers to use a runway different from that specified,
the pilot is expected to advise ATC.
2. At airports where a "runway use" program is established, ATC will
assign runways deemed to have the least noise impact. If in the interest of
safety a runway different from that specified is preferred, the pilot is
expected to advise ATC accordingly. ATC will honor such requests and advise
pilots when the requested runway is noise sensitive.
REFERENCE-
FAAO 8400.9, National Safety and Operational Criteria for Runway Use
Programs.
1. Will be operationally advantageous, or
2. Is requested by the pilot.
b. When conducting aircraft operations on other than the advertised
active runway, state the runway in use.
3-8-4. SIMULTANEOUS OPPOSITE DIRECTION OPERATION
Authorize simultaneous opposite direction operations on parallel runways, on
parallel landing strips, or on a runway and a parallel landing strip only
when the following conditions are met:
a. Operations are conducted in VFR conditions.
b. Two-way radio communication is maintained with the aircraft involved
and pertinent traffic information is issued.
PHRASEOLOGY-
TRAFFIC (description) ARRIVING/DEPARTING/LOW APPROACH, OPPOSITE DIRECTION
ON PARALLEL RUNWAY/LANDING STRIP.
c. The distance between the runways or landing strips is in accordance
with the minima in TBL 3-8-2.
