Final answer:
In aviation, the autopilot must be disengaged before the aircraft descends to the Minimum Descent Altitude (MDA) to ensure the pilot.
Step-by-step explanation:
The question pertains to the standard operating procedures in aviation regarding the use of autopilot during an approach. Autopilot systems are designed to assist the pilot during various phases of flight but must be disengaged at certain points to ensure safety and compliance with aviation regulations.
When approaching to land, the pilot must take manual control before the aircraft descends below the Minimum Descent Altitude (MDA). The specific altitude at which autopilot must be disengaged can vary depending on the aircraft type.
But it is generally required before reaching MDA. Disengaging the autopilot allows the pilot to have full control during the critical phase of the final approach and landing.
