2) give the position of the aircraft to waypoint 

3) to aid the pilot when fyling manually 

Command bars of the flight director may be present on the :

2) CDU

3) ADI

2) the correction on the pitch to be applied to join and follow the ILS glide slope 

3) the instantaneous deviation between the aircraft position and the ILS glide slope 

During a final approach, the FD system is engaged in the LOC mode (localizer axis holding) The position of the vertical command bar indicates: 

1) The position of the aircraft relative to the localizer axis

2) the roll attitude of teh aircraft

3) the correction on the bank to be applied to join and follows the localzer axis
