bank indicator
Low/Very LowTechnical/Formal
Definition
Meaning
A gauge or instrument in an aircraft that shows the degree of bank (angle of tilt) during a turn.
Any visual or digital display that indicates the lateral inclination of a vehicle or system; in broader technical contexts, a meter showing the rate or angle of roll.
Linguistics
Semantic Notes
Used almost exclusively in aviation and related technical fields. The word 'bank' refers specifically to the lateral tilt of an aircraft, not to financial institutions. It is a fixed compound noun where 'bank' modifies 'indicator'.

Learning
Memory Aids
Mnemonic
Imagine a plane tilting to BANK some money from the sky. The INDICATOR is the dial that shows the 'banking' angle. Bank = tilt, Indicator = shows it.
Conceptual Metaphor
VISUALISATION OF INVISIBLE FORCE: The indicator makes the invisible physical force of the turn (angular momentum) visible and measurable.

Common Pitfalls
Translation Traps (for Russian speakers)
- False friend: 'bank' does not mean 'financial institution' ('банк') here. It means 'крен' or 'наклон'.
- Do not translate 'indicator' literally as 'индикатор' without specifying context; 'указатель крена' or 'авиагоризонт' are more precise.
- The phrase 'bank indicator' is a specific technical term, not a free combination of two common words.
Common Mistakes
- Confusing with 'bank rate indicator' (finance).
- Using 'bank indicator' to describe a car's tilt.
- Saying 'banking indicator'.
- Treating it as two separate concepts: 'bank' and 'indicator'.

FAQ
Frequently Asked Questions
Not exactly. An artificial horizon shows both pitch and bank. A 'bank indicator' is often a simpler instrument showing only the bank (roll) angle, though it can be part of an artificial horizon system.
No, it is a highly technical term. Using it outside aviation or specific engineering contexts will likely cause confusion.
Its main purpose is to provide the pilot with visual information about the aircraft's angle of roll (bank) to enable coordinated turns and maintain controlled flight, especially when visual references outside the cockpit are unavailable.
In aviation, 'to bank' means to tilt or incline an aircraft laterally around its longitudinal axis. This usage is unrelated to the financial term and comes from the idea of 'tilting' or 'inclining'.
