If you go more than 1 dot low on the glideslope during an ILS approach, what should you do?

The best action to take when you find yourself more than one dot low on the glideslope during an ILS approach is to descend to the Minimum Descent Altitude (MDA) only after passing a specified fix. This is crucial because the specified fix serves as a reference point that ensures you are maintaining a safe altitude until you can properly assess your approach and confirm that you are still aligned with the runway and have the required visual references.

Descending to the MDA without reaching the specified fix may put you at risk of being too low and possibly missing required visual references necessary for a safe landing. Additionally, maintaining altitude until passing the fix allows you to avoid potential obstructions and ensures compliance with established procedures which are designed to enhance safety during the approach phase.

The process of adhering to these standards reflects the importance of situational awareness and disciplined adherence to approach protocols. This option aligns with the fundamental principles of IFR operations, which emphasize maintaining safe procedures even in situational stress.
