Final answer:
After a no-gyro surveillance or precision-based approach, ATC advises pilots to resume their own navigation with standard-rate turns, ensuring safe and predictable flight patterns.
Step-by-step explanation:
After completing a no-gyro surveillance or precision-based approach as directed by air traffic control (ATC), and when ATC advises to resume own navigation, all turns should be standard-rate turns. A standard-rate turn in aviation is one in which the aircraft turns at a rate of 3 degrees per second, which results in a complete 360-degree turn within 2 minutes. This rate of turn is considered standard for proper navigation and to maintain predictable and safe flight patterns, especially in visual meteorological conditions (VMC) where such procedures assist in collision avoidance. When ATC assigns navigation responsibility back to the pilot, these standard practices ensure that communication and coordination between pilots and ATC are maintained effectively.
