Narrative:

While giving instruction to a student on approach to gmu, the aircraft went below the GS approximately 400 ft prior to reaching judky LOM/IAF. The controller issued an altitude alert and corrective action was promptly taken. The events which led to this situation were appearing all at approximately the same time. The student was suffering from vertigo while a passenger in the back was becoming air sick. My attention from the flight instruments was distracted by this and also by the fact no positive down and locked information was obtained when the gear was lowered. In this situation, I feel more attention and emphasis should have been placed on the approach and the gear checked after breaking out. Ceiling considered.

THE CTLR ISSUED AN ALT ALERT AND CORRECTIVE ACTION WAS PROMPTLY TAKEN. THE EVENTS WHICH LED TO THIS SIT WERE APPEARING ALL AT APPROX THE SAME TIME. THE STUDENT WAS SUFFERING FROM VERTIGO WHILE A PAX IN THE BACK WAS BECOMING AIR SICK.
