In a CAT II operation at a decision height of 150 feet, how many approaches must a pilot in command log in the prior 12 calendar months for approval?

For a CAT II operation, the regulations set forth by aviation authorities like the FAA do not require a specific minimum number of approaches to be logged in the previous 12 calendar months for pilots in command. While there are certain recency requirements for different types of operations, CAT II operations at a decision height of 150 feet are not subject to a numerical logging requirement in this context. Instead, the focus is on a combination of currency, training, and proficiency, along with the completion of appropriate training and checks.

Understanding that individual airlines or operators might establish their own policies to ensure safety and proficiency is essential, but in terms of regulatory requirements, there is no minimum number of logged CAT II approaches necessary within that 12-month period for a pilot to be approved for such operations. Therefore, the absence of a logging requirement aligns with the correct answer in this scenario.
