Definition
Practice flight patterns flown on instruments that simulate the maneuvering required to align with a runway after completing an instrument approach when a straight-in landing is not possible. The pilot flies a rectangular pattern around a chosen reference point, holding a constant altitude and airspeed while making timed legs and standard-rate turns, to develop the precision needed for an actual circling approach to landing.
Plain English
A training exercise where the pilot flies a box-shaped pattern at a fixed altitude using only the instruments, to practice the kind of low-level maneuvering needed to line up with a runway after an instrument approach.
Context Anchor
Seen in instrument training when practicing how to transition from flying on instruments to maneuvering near the airport for landing.
Derivation
"Circling" here means flying around the airport at low altitude to position for landing on a runway other than the one the approach is aligned with. It does not mean flying in a circle — the actual path is rectangular.
Why Pilots Care
Allows safe landing alignment under instrument conditions and reduces the chance of a missed approach or runway misalignment.
Grounding Statement
Picture arriving near the airport from one direction, then carefully flying a controlled path around the airport so you can line up with a different runway for landing.
Intuition Check
Do not read “circling” as simply flying circles around the airport. In this context, it means controlled maneuvering near the airport to reach a safe landing position.
Example Sentence 1
During the lesson, the instructor had the student fly circling approach patterns under the hood to sharpen altitude control during the turns.
Example Sentence 2
During training, students practice circling approach patterns to prepare for landings where the final approach course does not match the runway heading.
