McFarlane Throttle Control Vernier-Assist MCVAS1222-15S FAA-PMA Approved

The McFarlane Aviation MCVAS1222-15S is a Vernier-Assist™ throttle control assembly with FAA-PMA approval. Its friction-based vernier mechanism provides fine throttle adjustment by rotating the knob, while normal coarse movement is made by pushing or pulling the control.

McFarlane’s patented Vernier-Assist design uses roller-action friction rather than threaded engagement, locking balls or pins. The control incorporates a friction lock to hold the selected setting and is designed to permit manual override when required.
