Question

What is the minimum HAT for a CAT II ILS?

Answer 1

The minimum HAT for a CAT II ILS varies, but it is usually around 100 feet.

Step-by-step explanation:

The minimum HAT (Height Above Threshold) for a CAT II (Category II) ILS (Instrument Landing System) varies depending on the specific airport and aircraft. CAT II ILS is a precision approach and landing system that allows aircraft to descend to a lower altitude and visibility compared to CAT I ILS.

In general, for CAT II ILS, the minimum HAT is usually around 100 feet. This means that the decision height, which is the point at which the pilot must decide whether to continue the approach or go-around, is around 100 feet above the runway threshold.

It's important to note that the specific minimum HAT for a CAT II ILS approach is determined by aviation authorities and may vary depending on factors such as airport facilities, runway length, aircraft performance, and air traffic control capabilities.
