What is the maximum headwind component for landing from a Category II approach?

The maximum headwind component for landing from a Category II approach is 16 knots. This limit exists to ensure safety and stability during the landing phase under reduced visibility conditions typical of Category II approaches. The lower visibilities require pilots to depend more on instruments, and excessive headwind can affect the aircraft's handling characteristics, potentially leading to difficulties in control during the landing rollout.

In this context, adhering to the headwind limitation is crucial as it helps maintain the necessary performance margins, reduces the risk of exceeding control capabilities, and enhances the overall safety of the operation. It is important for pilots to know and recognize these limits to conduct safe and effective landings, particularly when operating in environments with limited visibility.
