Definition
The standard rectangular flight path flown around an airport for landing in which all turns are made to the left. The pattern consists of the upwind, crosswind, downwind, base, and final legs, with the airplane keeping the runway off its left wing throughout the circuit.
Plain English
The normal way pilots fly around an airport before landing, where every turn in the pattern is a left turn. Unless the airport says otherwise, this is what pilots use by default.
Context Anchor
Used when learning or flying standard airport traffic patterns, especially when entering, departing, or practicing landings at an airport.
Derivation
“Left-hand” means using the left side or turning left. “Traffic pattern” means an organized path for aircraft moving around an airport. Together, the phrase tells you the direction of turns in that organized airport path.
Why Pilots Care
Using the left-hand traffic pattern keeps all aircraft moving in the same direction, reducing collision risk near busy airports.
Grounding Statement
Picture a rectangle around the runway where every corner is a left turn.
Intuition Check
Do not read “left-hand” as meaning the airplane stays on the left side of the runway at all times. In this term, it means the turns in the pattern are made to the left.
Example Sentence 1
Entering left-hand traffic for runway 27, the pilot turned downwind with the runway off the left wing.
Example Sentence 2
Unless otherwise specified by the airport or controller, pilots use a left-hand traffic pattern.
