ATC uses “Line Up and Wait” when a takeoff clearance cannot be immediately issued due to traffic or other reasons.
Pay close attention when instructed to “Line Up and Wait,” especially at night or during periods of low visibility.
When ATC issues intersection “Line Up and Wait” instructions and takeoff clearances, the intersection designator will be used.
If two or more aircraft call the tower ready for departure, one or more at the approach end of the runway and one or more at the intersection, the controller will state the location of the aircraft at the full length of the runway when authorizing that aircraft to taxi to Line Up and Wait or when clearing that aircraft for takeoff.
Before entering the runway, remember to:
Verify the ATC clearance.
Scan the full length of the runway, and Scan for aircraft on final approach or landing roll out.
Verify that the aircraft is on the assigned/correct runway.
Turn on landing lights only when takeoff clearance is received, or when commencing takeoff roll at an airport without an operating control tower.
Consider lining up slightly to the left or right of the centerline (approximately 3 feet) when holding in position at night so landing aircraft can differentiate your aircraft from runway lights.
When placing you into “Line Up and Wait,” ATC should advise you of any delay in receiving your takeoff clearance, for example, wake turbulence, traffic on an intersecting runway, or the reason/condition is clearly visible.
If a takeoff clearance is not received within a reasonable time after instructed to “Line Up and Wait,” contact ATC. (90 SECONDS)
Note: There have been some collisions and several incidents involving aircraft instructed to Line Up and Wait waiting for a takeoff clearance. The FAA’s analysis indicates that two minutes or more elapsed between the time an instruction was issued to “Line Up and Wait” and the resulting collision, land over, or go around by an aircraft cleared to land. Current guidance is to contact ATC if you have been holding in position for 90 SECONDS.
