Airplanes turn on the ground using a combination of nosewheel steering, differential braking, and differential thrust. For larger commercial jets in 2026, the pilot uses a small, steering-wheel-like control called a tiller, located on the left side of the cockpit, which hydraulically turns the nosewheel up to 70 degrees for sharp turns. At higher taxi speeds, the pilot can also use the rudder pedals to make smaller, more gradual adjustments. On smaller "taildragger" or light aircraft, pilots often rely on differential braking—pressing the top of the left brake pedal to slow the left wheel, causing the plane to pivot in that direction. In multi-engine aircraft, a pilot might also increase power to the "outer" engine (differential thrust) to help push the plane through a tight turn. This coordinated effort ensures that even a massive wide-body aircraft can navigate narrow taxiways and align perfectly with the runway for takeoff.
Excellent question! Airplanes turn while taxiing using a combination of systems, and the method depends heavily on whether the nose gear is steerable or not. Here’s a breakdown of the primary methods:
This is the most common and precise method for modern airliners and business jets. How it works: The pilot uses a small wheel or a tiller (often a “steering wheel” on the left side of the cockpit) to directly turn the nose landing gear. This works exactly like steering a car. Control: The tiller allows for sharp turns (up to about 70-80 degrees in some aircraft) needed for tight taxiways and getting in/out of gates. At slower speeds, the rudder pedals may also command a smaller degree of nose wheel steering (usually up to about 7 degrees) for gentle corrections on the runway.
This is the main way most small, single-engine propeller planes (like a Cessna 172) turn on the ground. How it works: The pilot presses the left rudder pedal to apply the brake on the left main wheels, causing that side to slow down. The right side continues rolling, making the airplane pivot left. The opposite is done to turn right. Use in Large Aircraft: It’s a backup system if nose wheel steering fails and is used for very fine, slow-speed adjustments or to tighten a turn initiated with the nose wheel steering.
This is especially effective on multi-engine aircraft (twin-engine props, jets, etc.). How it works: The pilot increases thrust (power) on the engine on
