two sets of controls in a vehicle, one for the person who is learning to operate the vehicle and one for the teacher

The aircraft was equipped with dual controls.

Flights are led by instructors who, of course, have dual controls.

When you speak to the instructor, make sure his car has dual controls.

I wouldn't even attempt to teach someone to drive in a vehicle without dual controls.

She was once in a car without dual controls when the learner lost control of the car.
