Landing Control

Factors to control

Throughout the landing procedure, there are 3 main aspects we have to control:

• The vertical location of the aircraft

• The horizontal location of the aircraft

• The approach speed of the aircraft

Within each stage of the landing procedure, each of the 3 main aspects are controlled differently. Here are the requirements at each stage:

Transition stage

• Vertical: controlled by waypoint manager

• Horizontal: controlled by waypoint manager

• Speed: does not need to be controlled

Slope stage

• Vertical: must be constantly and consistently changing (changingAltitude function)

• Horizontal: controlled by waypoint manager

• Speed: must be set as a certain approach speed (depends on current wind) (approachSpeed function)

Flare stage

• Vertical: throttle must be at idle to decrease altitude (throttleOff function)

• Horizontal: controlled by waypoint manager

• Speed: pitch up to slow flight (slowFlightSpeed function)

Decrab stage

• Vertical: throttle must be at idle to decrease altitude (throttleOff function)

• Horizontal: heading must be aligned with runway (heading given from CV)

• Speed: pitch up to slow flight (slowFlightSpeed function)

Touchdown stage

• Vertical: does not need to be controlled

• Horizontal: heading must be aligned with runway (heading given from CV)

• Speed: throttle at idle (throttleOff function)
