The Runway Advisory and Awareness System can give a number of advisories:
The Runway Advisory and Awareness System can give a number of advisories:


* Advisory when approaching a runway while taxiing
* Advisory when approaching a runway while taxiing if groundspeed is less than 40 knots


* Advisory when the aircraft is on the runway and aligned within 20 degrees with runway
* Advisory when the aircraft is on the runway and aligned within 20 degrees with runway
