Final answer:
Max MGT refers to the maximum speed an aircraft is allowed to travel on the ground. Different speed limits apply during start and inflight phases. Adherence to these limits is crucial for safety.
Step-by-step explanation:
Max MGT stands for Maximum Mach Ground Transportation and refers to the maximum speed an aircraft is allowed to travel on the ground. This speed is regulated for safety reasons, as excessive speeds on the ground can pose a risk to personnel and equipment.
During the start and inflight phases of a flight, different speed limits apply. On the ground, the maximum MGT is typically limited to around 20 knots (23 miles per hour) to ensure safe taxiing and takeoff. Once the aircraft is airborne, the restriction on speed is lifted, and the maximum MGT is determined by the aircraft's capabilities and any restrictions imposed by air traffic control or regulations.
It is important for pilots and ground personnel to adhere to these speed limits to ensure the safety of everyone involved in the operation of the aircraft.
