Definition
A pilot request asking ATC to read back the complete route of flight as it currently exists in the ATC computer, used to verify that the route the controller has on file matches the route the pilot is planning to fly.
Plain English
A way for a pilot to ask the controller, 'Please read me back my whole route from start to finish so I can check we both have the same one.'
Context Anchor
Seen in flight plan remarks, clearance delivery, and route-clearance discussions when a pilot wants the full routing from air traffic control.
Derivation
From 'Full Route Clearance' — 'full' meaning the entire route rather than just an amendment, and 'clearance' meaning the ATC-issued authorization to fly that route. The 'request' part makes it a pilot-initiated check rather than something ATC offers automatically.
Why Pilots Care
Ensures the pilot receives and understands the exact route ATC intends, reducing the chance of route deviations or airspace conflicts.
Intuition Check
Do not read FRC as a clearance by itself. It is a request for air traffic control to give the complete route.
Example Sentence 1
After sitting on the ground for two hours during a weather hold, the crew asked, 'Ground, Cessna 421CD, request FRC,' to make sure their route hadn't been amended.
Example Sentence 2
Instead of 'cleared as filed,' the controller issued an FRC detailing each waypoint and airway.
