Definition
A NOTAM contraction indicating that a navigation aid or instrument procedure has been flight-checked by the FAA and placed back into service on a temporary basis, pending full restoration or further inspection.
Plain English
The FAA test-flew the equipment and turned it back on for now, but the fix is not yet permanent.
Context Anchor
Seen in NOTAMs, especially notices involving navigation aids, instrument procedures, or other systems that may need an FAA flight inspection before their status changes.
Derivation
Built from three plain words: 'flight inspection' (the FAA's airborne check of a navaid or procedure to verify it works correctly) and 'temporary' (only for now). Together: the navaid passed its in-flight check well enough to be used, but only on a short-term basis.
Why Pilots Care
Alerts pilots that navigation signals or procedures may be temporarily unreliable or unavailable during the inspection.
Intuition Check
Temporary does not mean unimportant. Here it means the condition is not permanent, but it still applies until the NOTAM changes or is canceled.
Example Sentence 1
The NOTAM listed the VOR as FI/T, so the crew used it for the approach but cross-checked it against GPS.
Example Sentence 2
Pilots reviewed the FI/T entry before planning an approach using the affected localizer.
