4.2.2.1
Annunciation Criteria
RAAS determines the runway identifier for the end of the runway that is closest to the position of the aircraft. This
advisory is enabled when:
Aircraft is on the ground, and
Aircraft ground speed is less than 40 knots, and
Aircraft is within a specified distance from the runway.
NOTE:
The specified distance from the runway is a function of aircraft ground speed and closure angle with the runway; a higher ground speed will result in an earlier advisory (i.e. the aircraft is farther from the runway when the advisory is provided).
For example, the minimum distance from the runway that the advisory would be provided at very low ground speeds is 1 ½ times the runway width from the runway edge to the aircraft when approaching from 90 degrees relative to the runway. As the ground speed increases, the advisory is provided farther from the runway.
