The BAe 146 RJ has a function called 'TKOF TRK'. Passing 80kts the aircraft will use the direction in which the nose in pointing and apply that as runway track. So providing your going straight down the rwy at 80kts you'll climb out on runway track if you follow the flight directors. Very convenient on those windy days.
Any other aircraft with similar functions? (I've only flown the RJ to date)
