ILS

In which frequency band does an ILS glide slope transmit?

• AVHF.
• BSHF.
• CUHF.
• DEHF.

Every 10 kt decrease in groundspeed, on a 3◦ ILS glide path, will require an approximate:

• AIncrease in the aircraft’s rate of descent of 50 FT/MIN.
• BDecrease in the aircraft’s rate of descent of 50 FT/MIN.
• CDecrease in the aircraft’s rate of descent of 100 FT/MIN.
• DIncrease in the aircraft’s rate of descent of 100 FT/MIN.

The amplitude modulation and the color of an outer marker (OM) is:

• A3000 Hz, blue.
• B1300 Hz, blue.
• C400 Hz, blue.
• D400 Hz, amber.
