e/Vernier throttle

Information
has gloss	eng: A vernier throttle is a throttle often used in aircraft. It uses a cable and a screw mechanism to provide the operator precise control over an engine's operation. The concept is similar in use to vernier calipers which have a primary operation for gross (large) movement, and a secondary operation for fine movement. Like many other inventions that bear his name, the Vernier throttle is based on the work of mathematician Pierre Vernier.
