Which methodology applies if the ILS glideslope is out of service during an approach?

When the ILS glideslope is out of service during an approach, flying the LOC (Localizer) approach is an appropriate response. The Localizer provides lateral guidance to the runway centerline, allowing the pilot to align the aircraft properly for landing. While the glideslope typically offers vertical guidance to ensure a correct descent profile, the LOC approach allows pilots to still execute an instrument approach using only the horizontal component.

In this scenario, flying the LOC approach means the pilot will rely on the Localizer signal for lateral navigation. Pilots trained in instrument flight rules (IFR) are equipped to handle such situations, allowing them to maintain safety and precision in the approach even without vertical guidance.

Using alternative procedures might not be suitable or available for every situation, and solely depending on visual references could lead to safety concerns, especially in poor weather conditions or low visibility. Additionally, aborting the approach may not be necessary if there is a viable alternative, like the LOC approach, that allows for continued safe operation. Therefore, choosing to fly the LOC approach effectively utilizes the available systems to ensure a safe landing despite the loss of the glideslope signal.
