Definition
A regulation in Title 14 of the Code of Federal Regulations, Part 61, that sets the additional training and endorsement requirements a sport pilot must meet before operating in Class B, C, or D airspace, at an airport with an operating control tower, or in other airspace where communication with air traffic control is required.
Plain English
A rule that says a sport pilot must get extra training and a logbook sign-off from an instructor before flying into busier, controlled airspace or to airports with control towers.
Context Anchor
Seen in the Pilot’s Handbook discussion of Class B operating rules and pilot requirements, especially where sport pilot privileges are limited unless extra training and an endorsement are completed.
Derivation
Section comes from a word meaning a cut-off part or division. In regulations, a section is one numbered piece of a larger rule. Here, 61 means the rule is in Part 61, which covers pilot certification, and .325 identifies the specific rule inside that part.
Why Pilots Care
A sport pilot who has not met the requirements of this section cannot legally enter Class B airspace.
Intuition Check
Do not read section 61.325 as a page or paragraph in the handbook. It is a specific federal regulation that the handbook is pointing you to.
