Definition
The section of the Federal Aviation Regulations that governs parachute operations in the United States. It sets the rules for when, where, and how parachute jumps may be conducted, including required notifications to Air Traffic Control, restrictions over congested areas and controlled airspace, equipment requirements, and the responsibilities of the pilot in command of the jump aircraft.
Plain English
It is the chapter of the federal flight rules that covers skydiving and other parachute jumps -- what is allowed, what permission is needed, and what the pilot flying the jumpers must do.
Context Anchor
Seen when studying parachute jumps, skydiving activity near airports, drop zones, and pilot responsibilities around parachute operations.
Derivation
CFR stands for Code of Federal Regulations, the official collection of rules issued by U.S. government agencies. Title 14 covers Aeronautics and Space, and within it each numbered 'part' deals with one topic. Part 105 happens to be the part assigned to parachute operations.
Why Pilots Care
Pilots who drop parachutists must follow these rules to avoid regulatory violations and to keep the operation safe for everyone involved.
Intuition Check
Do not read “part” as a casual piece of a book. In FAA use, a “part” is a specific numbered section of federal aviation rules.
Example Sentence 1
Before the skydiving flight, the pilot reviewed 14 CFR part 105 to confirm the required ATC notification and altitude rules.
Example Sentence 2
A skydiving business must maintain compliance with 14 CFR Part 105 for every parachute operation it conducts.
