Definition
The set of navigation performance and equipment requirements that an aircraft must meet to fly a particular route. These specifications cover the accuracy, integrity, and capability of the navigation systems on board, and they determine which routes and procedures the aircraft is authorized to operate on.
Plain English
The rules that say what navigation gear and accuracy your aircraft needs in order to legally fly a given route. If your aircraft and equipment meet the rules, you can fly the route. If not, you can't.
Context Anchor
Seen in flight planning, instrument procedures, route descriptions, and navigation system setup before or during a flight.
Why Pilots Care
Accurate route specifications prevent airspace incursions, fuel exhaustion, and loss of separation from other traffic.
Grounding Statement
The phrase points to the practical instructions that keep the aircraft on the intended path from start to finish.
