the right and the pitch bar will deflect upwards. The pilot will then pull back on the control column while banking to the right. Once the aircraft reaches the proper bank angle, the FD vertical bar will center and remain centered until it is time to roll back to wings level (when the heading approaches 090°). When the aircraft approaches FL200 the FD horizontal bar will deflect downwards thus commanding the pilot to lower the nose in order to level off at FL200.

sources. The flight data computer integrates all of the data such as speed, position, closure, drift, track, desired course, and altitude into a command signal. The command signal is displayed on the attitude indicator in the form of command bars, which show the pitch and roll inputs necessary to

Flight director (FD) modes integrated with autopilot systems perform calculations for more advanced automation, like "selected course (intercepting), changing altitudes, and tracking navigation sources with cross winds." FD computes and displays the proper pitch and bank angles required for the

The pilot simply keeps the aircraft symbol on the attitude indicator aligned with the command bars, or allow the autopilot to make the actual control movements to fly the selected track and altitude. A simple example: The aircraft flies level on 045° heading at
