Hmmm, I do fly a Cessna Citation with RAAS. Apart from other things, if I`d try to takeoff from a runway less (rather TODA) than 4000 ft it yells at me ("short runway"). 777 hasnīt got that thingy?
Next, we have the Jepp plate on the MFD with a little airplane on it showing our position. 777 hasnīt got that?
Actually yes 777 has RAAS. Both Boeing and Honeywell have had the ability to deliver RAAS in the 777 since late 2009 (after this incident) and I believe United is operating with it now. The Boeing version will callout "On Runway, x,xxx Remaining" if the aircraft aligns with less than an operator specified distance remaining, and as the aircraft exceeds 40 knots will then yell "Caution Short Runway, Short Runway".
