Narrative:
The new raas (runway awareness advisory system) on the 777-300 will give two disturbing and distracting audio cautions when taking off on [bos] runway 9. We got an 'approaching 4L' caution followed by 'runway short' caution as we started the takeoff roll. This is very distracting; and I suspect a rejected takeoff will occur in the future on this 7000 ft runway...because of the audio cautions causing confusion.
