Which type of publication is not included in Technical Manuals?

The Flight Operations Handbook is not classified as a Technical Manual. Technical Manuals are specific types of documents that provide instructions and procedures for the maintenance, repair, and operation of a particular system or equipment. They typically include detailed specifications, maintenance procedures, and troubleshooting guides.

In contrast, the Flight Operations Handbook serves a different purpose by focusing on flight-related procedures, operations, flight crew responsibilities, and aircraft performance information specific to pilots and flight operations. This publication is aimed more at operational usage rather than maintenance and technical aspects, which is why it does not fall under the category of Technical Manuals.

On the other hand, the Interactive Electronic Technical Manual, Circulars, and Maintenance Procedure Manual are all considered Technical Manuals as they provide vital information related to aircraft systems, maintenance procedures, and regulatory guidance that are essential for the support and upkeep of specific aviation systems.
