What should a pilot do if the LOM is out of service during approach?

When the Locator Outer Marker (LOM) is out of service during an approach, the pilot should cross-tune to identify the Final Approach Fix (FAF) via the ALS 260 radial. This is important because the LOM provides lateral guidance as well as a position indicator for the approach. If it's non-operational, other navigational resources are essential for safely identifying the FAF and ensuring proper alignment with the approach.

By using the ALS 260 radial, pilots can still accurately determine their position and ensure they remain on the correct flight path to the runway. This method allows for effective navigation even in the absence of the LOM guidance, thus preventing potential missed approaches or disorientation.

Choosing to abort the approach or request an alternative approach might be unnecessary when effective navigational solutions are available. Continuing without any adjustments could lead to issues with misidentification of the FAF or failure to maintain proper alignment, which could compromise safety during the approach. Therefore, utilizing cross-tuning as a backup strategy is the best practice in this scenario.
