Research Notes
Section 91.191 establishes the Category II Manual requirement for operators conducting Cat II approaches. The manual codifies the operator's procedures, training, and quality control for low-visibility operations.
What the manual contains: Operating procedures, training programs, maintenance procedures, equipment requirements, weather minima procedures, and quality control procedures specific to Cat II operations.
Practical scope: Cat II Manuals are typical of Part 121/135 ops specs. Part 91 Cat II operators must develop their own manual approved by the FAA before conducting Cat II approaches.
Reference: AC 120-29A; FAA Order 8900.1 Volume 4, Chapter 5 for inspector guidance on Cat II Manual approval.
