Separate departing aircraft from an aircraft using a nonintersecting runway when the flight paths intersect by ensuring that the departure does not begin takeoff roll until one of the following exists:
The preceding aircraft has departed and crossed the departure runway, or is turning to avert any conflict. (See FIG 3-9-13).
FIG 3-9-13 Intersecting Runway Separation
A preceding arriving aircraft has completed the landing roll and will hold short of the projected intersection, passed the projected intersection, or has crossed over the departure runway (See FIG 3-9-14 and FIG 3-9-15).
FIG 3-9-14 Intersecting Runway SeparationFIG 3-9-15 Intersecting Runway Separation
If the extended centerline of a runway crosses a converging runway or the extended centerline of a converging runway at a distance of 1NM or less from either departure end, apply the provisions of Para 3-9-8, Intersecting Runway/Intersecting Flight Path Operations, unless the facility is using aids specified in a facility directive, (may include but are not limited to, Arrival/Departure Window (ADW), ASDE-X Virtual Runway Intersection Point (VRIP), cut-off points or automation). (See FIG3-9-16 and FIG 3-9-17.)
REFERENCE
FAA Order JO 7210.3, Para 10-3-15, Go-Around/Missed Approach
Separate aircraft taking off behind a departing aircraft on a crossing runway if projected flight paths will cross (See FIG 3-9-18):
Heavy, large, or small behind super - 3 minutes.
Heavy, large, or small behind heavy - 2 minutes.
Small behind B757 - 2 minutes.
FIG 3-9-18 Intersecting Runway Separation
NOTE: Takeoff clearance to the following aircraft should not be issued until the time interval has passed from when the preceding aircraft began takeoff roll.
Separate aircraft departing behind a landing aircraft on a crossing runway if the departure will fly through the airborne path of the arrival (See FIG 3-9-19):
Heavy, large, or small behind super - 3 minutes.
Heavy, large, or small behind heavy - 2 minutes.
Small behind B757 - 2 minutes.
FIG 3-9-19 Intersecting Runway Separation
Do not approve pilot requests to deviate from the required time interval if the preceding aircraft requires wake turbulence separation.
