AIM Text
Increased traffic congestion, aircraft in climb and descent attitudes, and pilot preoccupation with cockpit duties are some factors that increase the hazardous accident potential near the airport. The situation is further compounded when the weather is marginal, that is, just meeting VFR requirements. Pilots must be particularly alert when operating in the vicinity of an airport. This section defines some rules, practices, and procedures that pilots should be familiar with and adhere to for safe airport operations.

The short answer
This AIM section is FAA advisory guidance introducing airport operations. It explains why the airport vicinity is high-risk—traffic congestion, aircraft in climb and descent attitudes, pilot preoccupation with cockpit duties, and marginal weather just meeting VFR. It frames the rules, practices, and procedures pilots should follow for safe operations, supporting 14 CFR Part 91 airport rules.
Research Notes
Common Questions
Why is operating near an airport more hazardous?
How does marginal weather affect airport-area risk?
The AIM notes the situation is further compounded when weather is marginal—just meeting VFR requirements—so pilots must be particularly alert when operating in the vicinity of an airport.
Is this AIM section a regulation pilots must obey?
No. The AIM is advisory guidance. This section defines rules, practices, and procedures pilots should be familiar with and adhere to for safe airport operations, supporting the underlying 14 CFR Part 91 requirements.
