What is the duration required to complete a 360-degree turn at a rate 1 turn?

To understand the duration required to complete a 360-degree turn at a rate of 1 turn, we need to consider what is meant by a "turn." Typically, in aviation, a turn rate of one turn per minute indicates that the aircraft completes one full rotation, or 360 degrees, in one minute.

Therefore, if an aircraft is flying at this specific turn rate, it will take exactly one minute to make a complete 360-degree turn. The implication of the question is that the turn is uniform, and the rate is constant throughout the maneuver. This understanding is crucial for pilots and helps in managing flight operations and ensuring safety at different stages of flight.

The other options suggest durations greater than what is supported by the definition of a turn rate of one turn per minute, therefore misinforming the correct timing necessary to complete the maneuver.
