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 if groundspeed is less than 40 knots
{| class="wikitable"
 
|-
* Advisory when the aircraft is on the runway and aligned within 20 degrees with runway
! Feature !! RAAS
 
|-
* Advisory when the aircraft is on a short runway
| On runway and alignment < 20 degrees || {{Progressbar|100}}
 
|-
* Advisory of remaining distance to the end of the runway during a landing while groundspeed is more than 40 knots and AGL less than 100 feet
| On short runway, announcing remaining distance || {{Progressbar|100}}
 
|-
* Advisory of remaining distance during RTO after passing 50 % of runway
| On runway (reminder) || {{Not done}}
|-
| Approaching runway when taxiing and groundspeed < 40 knots || {{Progressbar|100}}
|-
| Approaching runway (airborne) when distance < 3 nm, alignment < 20 degrees, AFE is 300 - 450 ft or  550 - 750 ft || {{Progressbar|100}}
|-
| Approaching runway, announcing available distance || {{Progressbar|100}}
|-
| Distance remaining (during rollout) || {{Progressbar|100}}
|-
| Distance remaining after rejected takeoff, past 50 % of runway and 7 knots below maximum groundspeed || {{Progressbar|100}}
|-
| Runway end when distance remaininig < 100 feet and groundspeed < 40 knots || {{Not done}}
|-
| Taxiway takeoff when groundspeed > 40 knots while not on runway || {{Not done}}
