What is the limitation regarding the use of autopilot?

The limitation regarding the use of autopilot is that it must not be used below 1,000 feet AGL (Above Ground Level). This is primarily due to safety concerns, as operating an autopilot below this altitude can increase the risk of mishandling the aircraft, especially during critical phases of flight such as approach and landing. At lower altitudes, pilots need to maintain a higher level of situational awareness and control to respond to any emergencies or unexpected situations that may arise.

Maintaining manual control of the aircraft below 1,000 feet ensures that pilots are fully engaged and able to make quick decisions, thereby enhancing safety. This limitation aligns with standard aviation practices that prioritize pilot awareness and the complexity of managing an aircraft at lower altitudes.
