While being RADAR vectored, what is the correct procedure?

When being RADAR vectored, the correct procedure includes repeating all headings, altitudes, and altimeter settings assigned to ensure clear communication and understanding between the pilot and air traffic control. This process is essential for maintaining situational awareness and operational safety, as it confirms that the pilot has accurately received and understood the controller's instructions.

Repetition of the complete set of instructions—including headings, altitudes, and altimeter settings—serves as a verification step that can help prevent misunderstandings that may lead to dangerous situations during flight. Air traffic controllers may issue several instructions in quick succession, and by repeating each one, the pilot can clarify any potential confusion and execute their flight maneuvers accurately and efficiently.

This procedure facilitates safe interactions and navigational compliance, which is crucial especially in busy airspace where precise coordination is essential for maintaining separation between aircraft.
