5-13-2. MONITOR AVAILABILITY
- Inform the aircraft of the frequency on which monitoring information will be transmitted if it will not be the same as the communication frequency used for the approach.
- RADAR MONITORING ON LOCALIZER VOICE (frequency),
- and if applicable,
- CONTACT (terminal control function) (frequency, if required) AFTER LANDING.
- If the approach is not monitored, inform the aircraft that radar monitoring is not available.
- RADAR MONITORING NOT AVAILABLE.
- If conditions prevent continued monitor after the aircraft is on final approach, advise the pilot. State the reason and issue alternate procedures as appropriate.
- (Reason), RADAR MONITORING NOT AVAILABLE, (alternative instructions).
NOTE: Approach monitoring is a vital service, but during the approach, the controller acts primarily as a safety observer and does not actually guide the aircraft. Loss of the radar monitoring capability (and thus availability) is no reason to terminate an otherwise good instrument approach. Advise the pilot that radar contact has been lost (or other reason as appropriate), that radar monitoring is not available, and of actions for the pilot to take in either proceeding with or breaking off the approach; i.e., contact tower, remain on PAR frequency, etc.
