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.
It works very well in the RJ. The 717 has a similar system but goes to Heading when airborne and very quickly slides off the extended CL at the slightest hint of changing wind. WOFTAM. The pilot has to pull TRK to make it stay "maintaining runway track".
