Definition
A sheet of microfilm, similar to microfiche, used to store aviation maintenance and technical publications in a compact, miniaturized photographic format that must be read with a special viewer or reader.
Plain English
A small plastic sheet holding tiny photo-shrunk pages of aviation manuals. You read it by placing it in a magnifying viewer that enlarges the pages on a screen.
Context Anchor
Most often encountered in older aircraft maintenance records, parts catalogs, service information, or aviation libraries that still use microfiche files.
Derivation
From 'aero' (relating to aircraft, from Greek 'aer' meaning air) combined with 'fiche' (French for 'card' or 'slip'). The term distinguishes aviation-specific microfiche from the general microfiche used in other industries.
Why Pilots Care
Mechanics and pilots reviewing older aircraft documentation may still encounter aerofiche records, especially when researching service history, legacy parts, or airworthiness information for older aircraft.
Intuition Check
Aerofiche is not an aircraft part or a flight instrument. It is a storage format for aviation documents.
Example Sentence 1
The shop kept a drawer of aerofiche containing every service bulletin issued for the aircraft type.
Example Sentence 2
Many legacy aircraft still rely on Aerofiche because the complete maintenance library fits in a small binder rather than stacks of paper.
