If the ILS glideslope component is out of service, how do you determine the missed approach point?

The correct approach to determining the missed approach point when the ILS glideslope component is out of service is to rely on plate dependence. This means that pilots would refer to the approach procedure charts, which provide specific guidance for situations like this.

When the glideslope is inoperative, the chart typically indicates how to proceed with the approach without that vertical guidance. The missed approach point is defined within these charts, allowing pilots to have a structured procedure to follow. This maintains safety by ensuring that pilots adhere to established protocols rather than making decisions based solely on their own judgment or other resources that may not be as reliable in this context.

Other methods, such as using GPS data, following ATC instructions, or pilot discretion, may have varying degrees of reliability or may not provide the precise information needed for the missed approach. In contrast, plate dependence ensures adherence to published regulations and procedures, which is critical for the integrity of flight operations.
