What does a GSI indicating two dots above the glideslope mean?

The indication of two dots above the glideslope on a Ground Speed Indicator (GSI) signifies that the aircraft is above the ideal glideslope for landing. In this context, the correct interpretation is to refrain from descending below the localizer minima. The localizer minima represent the lowest altitude to which a pilot can descend while still maintaining a safe approach to the runway based on the localizer signal. This ensures that the aircraft stays within safe operating limits during the approach phase.

By maintaining awareness of the glideslope indications, pilots can make informed decisions to stabilize their approach and avoid potential obstacles or barriers associated with descending too low before reaching the airport. This understanding helps in promoting safety and effectiveness during instrument approaches.
