What should a pilot do if an electronic glide slope malfunctions during an ILS approach but the VASI is visible?

In the event of an electronic glide slope malfunction during an Instrument Landing System (ILS) approach, the pilot's actions must prioritize safety while making effective use of available visual aids. If the Visual Approach Slope Indicator (VASI) is visible, the pilot can rely on it as a reference for a safe descent path. The VASI provides visual guidance that indicates whether the aircraft is above, below, or on the correct glide path.

Continuing the approach using the VASI glide slope allows the pilot to maintain situational awareness and effectively control the descent towards the runway. The use of the VASI is particularly valuable in this situation because it complements the visual cues needed for landing, especially when electronic systems experience issues. Pilots are trained to adapt to various scenarios, and utilizing the VASI in this case ensures adherence to a safe glide slope, thereby increasing the chances of a successful landing.

While options such as abandoning the approach or climbing and going around may be considered in specific situations, they do not effectively utilize the information and guidance provided by the VASI in this scenario. Contacting air traffic control could provide additional support but is not necessary if the pilot is able to safely manage the approach using the visual references available. Therefore, continuing the approach using
