Question 36

Relieving a Controller from an Operating Position

Answer 36

The controller being relieved is responsible for the position during the pre-relief monitoring process.
When relieving a controller from an operating position:[4]
1. If the position is equipped with an electronic log-on system that records time preparing to accept responsibility for the control position, and time on duty in the position, log on according to unit directives. A trainee is expected to log on with the OJI and to log off when leaving the position.
2. Observe operational situations and equipment.
3. Listen to communications.
4. Observe current and pending traffic.
5. Verify the position transfer checklist.
6. Correlate information.
7. Inform the controller being relieved that the position has been reviewed and request a verbal briefing.
8. Exchange all pertinent data and ask questions, as appropriate, to ensure understanding.
9. After the verbal briefing, state, or otherwise indicate clearly to the controller being relieved, that position responsibility has been transferred.

[4] “Assuming responsibility for a position” includes a position being combined or a position being split.

Question 37

* Review appropriate operational information, for example, NOTAMs, aerodrome conditions, equipment status, and weather information.

Question 38

Responsibilities When Being Relieved from an Operating Position

Answer 38

The relieving controller is responsible for the position during the post-relief procedures.
When being relieved from your operating position:
* Provide a verbal briefing to the relieving controller using the position transfer checklist.
* If the communication system permits, record the verbal briefing.
* Remain with the relieving controller for monitoring purposes. During this time, reinforce the position relief briefing and help the relieving controller become familiar with the position.
* When combining a position, perform the post-relief overlap procedures at the position where the operation was combined.
