The flight instructor was created by programmer Andrew Grant and voiced by Tom Streit. It monitors the player's controller input during "each frame of animation". If a maneuver is attempted, the instructor "interpolates the initial control movements" and predicts which maneuver is being performed. The instructor then gives advice on how to complete the maneuver and offers guidance if a mistake is made. Grant believed that the code is sometimes "too picky", and he stated that it expects players to perform maneuvers more precisely than is humanly possible. The team initially planned to include an online multiplayer component, which would have allowed 64 planes to fly in the same area—thereby giving players the ability to compete with one another. However, the feature was not implemented into the final game. The staff members also sought to include aerobatic competitions in which the player could participate, but the idea was dropped because of difficulties with realism. Problems with artificially intelligent judges were also a factor in the feature's removal.
