What does TAT stand for in the context of engine maintenance?

Turnaround Time (TAT) is a critical term in the context of engine maintenance and aviation operations. It refers to the time taken to service an aircraft or its engines, from when it lands to when it is ready for its next flight. This encompasses all maintenance activities, inspections, and any repairs that need to be performed to ensure that the aircraft meets safety and operational standards.

Minimizing turnaround time is essential for maximizing operational efficiency, as it directly impacts the aircraft's availability for flights and overall productivity for the airline or maintenance organization. Timely and effective maintenance practices can significantly reduce TAT, resulting in cost savings and improved service reliability.

The other options, while they may suggest relevant terms in different contexts, do not accurately define the concept of turnaround time within engine maintenance, making them less applicable in this scenario.
