Which of the following is NOT a classification of operations according to CASR parts?

The classification of operations according to the Civil Aviation Safety Regulation (CASR) parts outlines various categories of aviation-related activities, each with specific regulations and requirements. The correct answer indicates that military operations are not classified under the mentioned CASR parts.

General operations, aerial work, and air transport large are clearly defined categories under CASR regulations. Part 91 covers general aviation operations, which are typically non-commercial and include private flying, while Part 138 pertains to aerial work operations, which involve tasks like survey flights or agricultural spraying. Part 121 governs the operations of air transport large, specifically detailing the requirements for commercial air carriers operating large aircraft.

In contrast, military operations are generally governed by separate regulations that are not included in the civilian classification system of CASR. Military aviation typically falls under different authority and does not follow the same structure or regulatory parts as civilian operations, leading to its exclusion from the classifications listed in CASR.
