drift indicator
LowTechnical
Definition
Meaning
A device or instrument that shows the amount an aircraft is drifting sideways from its intended course due to wind.
Any instrument or visual method for showing lateral deviation from a set course or path; by metaphorical extension, a sign or measure showing a gradual change in opinion, market prices, or other variable.
Linguistics
Semantic Notes
Primarily an aviation term. Its meaning relies on the specific sense of 'drift' as lateral movement from wind. In metaphorical use, 'indicator' retains its function of showing a trend.

Translation Traps (for Russian speakers)
- Do not translate 'drift' as 'снос' in a non-aviation context; it's too specific. Avoid confusing with 'индикатор заноса' (skid indicator). The compound is a single technical term.
Common Mistakes
- Using 'drift indicator' to mean 'trend' in non-technical writing.
- Confusing it with a 'turn indicator' (shows aircraft bank).
- Misspelling as 'driftindicator' or 'drift-indicator' inconsistently.

FAQ
Frequently Asked Questions
No. A compass shows magnetic heading. A drift indicator shows the difference between the aircraft's heading and its actual track over the ground due to wind.
It can, but it is rare and highly technical sounding. For example: 'The weekly poll serves as a drift indicator for public opinion.' In most contexts, 'trend indicator' or 'barometer' is preferred.
Most modern aircraft use integrated electronic systems (like GPS and flight management computers) to calculate and display drift/correction. Traditional visual drift indicators are now more common on older or light aircraft.
Yes. It is a fixed, open compound noun where 'drift' modifies 'indicator' to specify its type. It is often hyphenated in British English ('drift-indicator') when used attributively.
