Definition
A NOTAM contraction indicating that a navigation aid, instrument procedure, or facility has been permanently flight-inspected and approved for operational use following installation, modification, or commissioning.
Plain English
This means the equipment or procedure has been checked from the air, found to work correctly, and is now permanently approved for pilots to use.
Context Anchor
Seen in NOTAMs, especially with navigation facilities, instrument procedures, or other items that may need airborne checking before pilots rely on them.
Derivation
‘Flight inspection’ refers to checking equipment by flying an aircraft past or through its signal to verify it works correctly. ‘Permanent’ here means the approval is lasting, not a temporary or trial status.
Why Pilots Care
Confirms the facility meets permanent inspection standards, allowing safe reliance for navigation.
Intuition Check
Permanent does not mean you can forget about the NOTAM. It means the flight-inspected change is intended to remain in effect until it is officially published, changed, or cancelled.
Example Sentence 1
The NOTAM showed FI/P status for the new ILS, confirming it had been flight-inspected and was approved for use.
Example Sentence 2
Controllers referenced the FI/P status before clearing the flight for the procedure.
