Step-by-step explanation:
The CAT II weather minimums refer to the weather conditions required for aircraft to operate under Category II Instrument Landing System (ILS) approaches. There are two types of CAT II weather minimums: operational and training.
Operational CAT II weather minimums are applicable to aircraft operating in revenue service. These minimums typically include a decision altitude (DA) or decision height (DH) of 100 feet above the runway, and a runway visual range (RVR) of at least 1,200 feet.
Training CAT II weather minimums, on the other hand, are used for flight crew training and qualification purposes. They are typically more stringent than operational minimums, with a DA/DH of 50 feet and an RVR of at least 700 feet.
