Definition
A pilot responsibility concept covering the accuracy, currency, and intended-use boundaries of the data loaded into and displayed by avionics, navigation systems, and electronic flight tools. The pilot must verify that the data is correct, current, and being used only for the purposes the manufacturer and regulator approve.
Plain English
The information your cockpit equipment shows is only as good as the data put into it, and that data is only meant to be used in certain ways. The pilot is responsible for checking that the information is right, up to date, and being used for what it was designed for.
Context Anchor
Seen when using aviation apps, electronic charts, databases, weather products, performance tools, or other digital information for flight planning or in-flight decisions.
Derivation
‘Integrity’ comes from the Latin integer, meaning ‘whole’ or ‘untouched’ — so data integrity means the data is complete and uncorrupted. ‘Limitations to use’ simply means the boundaries within which the data is approved or appropriate to rely on. Together: is the data sound, and am I using it the way it was meant to be used?
Why Pilots Care
Relying on corrupted or outdated data can produce navigation errors, airspace violations, or incorrect performance calculations that directly affect safety.
Analogy
It is like using a road map: first you make sure the map is current and complete, then you make sure it is meant for the kind of trip you are taking.
Intuition Check
Integrity does not mean honesty or good character here; it means the data is accurate, complete, current, and unchanged. Limitations does not mean the data is useless; it means there are specific boundaries on how it should be used.
Example Sentence 1
Before departure, the pilot checked the navigation database expiration date to confirm data integrity for the planned IFR flight.
Example Sentence 2
The pilot reviewed the limitations to use for the electronic approach plates and carried paper backups when the tablet battery was marginal.
