Definition
A single control yoke mounted on a pivoting arm so it can be swung (thrown over) from the pilot's side of the cockpit to the copilot's side, allowing either seat to fly the aircraft but not both at the same time. Found in some light aircraft, most notably certain Beechcraft Bonanza models.
Plain English
One yoke that can be swung across to whichever seat is flying. Only one person can use it at a time.
Context Anchor
Seen in cockpit layout descriptions, aircraft equipment lists, and pilot operating handbooks for some light airplanes.
Derivation
From 'throw over,' meaning to swing or move something across to the other side. The yoke is literally thrown across the cockpit on its pivoting arm.
Why Pilots Care
It reduces weight and complexity in training aircraft while still allowing both occupants to fly the airplane.
Intuition Check
Throw-over control does not mean a control that is thrown or released. It means a control that can be moved over from one seat position to the other and locked there.
Example Sentence 1
The Bonanza had a throw-over control, so the instructor swung the yoke across to the student before takeoff.
Example Sentence 2
With the throw-over control in the left position the student flew the pattern while the instructor observed.
