Final answer:
The minimum C-17 equipment requirements for a CAT II ILS are a radio altimeter, glideslope receiver, localizer receiver, and autopilot.
Step-by-step explanation:
The minimum C-17 equipment requirements for a CAT II ILS (Instrument Landing System) are as follows:
- Radio altimeter: This instrument measures the height above the ground during an approach and landing.
- Glideslope receiver: This equipment receives the glideslope signal, which provides vertical guidance to the aircraft during the approach.
- Localizer receiver: This equipment receives the localizer signal, which provides horizontal guidance to the aircraft during the approach.
- Autopilot: An autopilot system is essential for maintaining precise flight paths and control during the approach.
By ensuring that these minimum equipment requirements are met, the C-17 aircraft can safely operate in CAT II ILS conditions, which involve lower visibility and lower cloud ceilings than CAT I conditions.
