Plain English Meaning

Rules that say how long you are allowed to keep using a chart or procedure document before you must throw it out and use the new version. After that date, the old chart is no longer legal or safe to fly with.

Full Definition

Restrictions on how long an instrument approach chart, procedure, or related navigation publication may be retained and used after issuance, before it must be replaced with the current revision. Storage limitations define the latest date a chart remains authorized for use in operations, after which the chart is considered out of date and must not be used for navigation.

Context Anchor

Seen when using installed avionics, GPS units, flight management systems, or electronic chart databases for instrument procedures.

Derivation

‘Storage’ comes from Old French ‘estorer,’ meaning to keep or preserve. ‘Limitation’ is from Latin ‘limitare,’ to set a boundary. Together, the term simply means the boundary on how long something kept on hand may still be used — in this case, navigation and procedure documents.
