Landing weather minimums: IFR: All certificate holders

This regulation increases landing minimums for Part 121 pilots who haven't yet logged 100 hours as pilot in command in their current aircraft type. Until reaching that threshold, they must add 100 feet to the Decision Height/Minimum Descent Altitude and one-half mile (or equivalent RVR) to visibility minimums at their destination—but never below 300 feet and 1 mile, and never higher than the airport's alternate minimums.

Pilots can reduce the 100-hour requirement in two ways: by crediting one landing in that aircraft type for each hour (up to 50% reduction) if they have 100+ hours as PIC in another Part 121 aircraft type, or—if transitioning from Part 135 large aircraft operations with the same carrier—by counting up to 50 hours of Part 91 time in the same type.

Category II approaches and other special authorizations don't apply until the pilot meets the 100-hour requirement.
