Vernier throttle
Encyclopedia
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
.
Vernier throttles are commonly used in aircraft. A similar mechanism is also used in reciprocating (gasoline) aircraft engines to set the mixture to an appropriate value for a given altitude.
Throttle
A throttle is the mechanism by which the flow of a fluid is managed by constriction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases , but usually decreased. The term throttle has come to refer, informally and incorrectly, to any mechanism by which...

Vernier scale
A vernier scale is an additional scale which allows a distance or angle measurement to be read more precisely than directly reading a uniformly-divided straight or circular measurement scale...
