McFarlane Aviation Products has received FAA PMA approval for its Vernier-Assist Throttles.
“Finally, the wait is over for safer, smoother, more precise throttle controls,” company officials said.
“McFarlane’s new assembly offers the best of traditional friction-type and vernier-type throttle controls,” company officials continued. “Operating on friction alone eliminates the need for threads, locking balls, and pins. Simply turn the knob for fine adjustments, or push in or out for coarser movement. An adjustable friction lock secures the control in position, but is easily overridden in case of an emergency.”
“Our Vernier-Assist throttles are safe, precise, and dependable,” added Engineering Manager Austin Beine. “These throttles are completely jam-proof. Our design provides precise rotary adjustments with the quick response of a friction-type throttle control.”
Without the release button or locking thread that are subject to jamming, the McFarlane patented roller action uses only friction to drive the vernier action, company officials explained.
The controls are FAA-PMA approved for installation in most single engine aircraft.
