synchroscope

9.9

An instrument that shows whether two parts, like engines or generators, turn at the same speed

noun
/ˈsɪŋkrəˌskoʊp/

Specialized

: sincronoscopio

The copilot carefully monitored the synchroscope to ensure both engines were running at the same speed.

Examples

Engineers used a synchroscope to match the generators before connecting them to the power grid.
A faulty synchroscope can lead to unbalanced propellers and decrease flight efficiency.
The synchroscope showed that the engines were perfectly aligned.
Have you checked the synchroscope before takeoff?
The copilot carefully monitored the synchroscope to ensure both engines were running at the same speed.
Engineers used a synchroscope to match the generators before connecting them to the power grid.
A faulty synchroscope can lead to unbalanced propellers and decrease flight efficiency.

Surface Forms

synchroscope singular

synchroscopes plural

Morphology

synchroscope = scope (semi-transparent) = synchro + scope

The word is built from the recognizable instrument suffix '-scope' plus a technical form meaning synchronization, but the full specialized aviation sense is not fully predictable for many learners.

Etymology

Synchroscope comes from two parts: synchro- meaning 'same time' or 'together' and -scope meaning 'to look' or 'see', just like in telescope. So a synchroscope is literally a tool to 'look' at whether two machines are moving at the same time, which is why pilots and engineers use it to match engine speeds.
