Definition
The office within the Federal Aviation Administration responsible for collecting, maintaining, and publishing official aeronautical information used for flight planning and navigation in the United States, including instrument approach procedures, departure procedures, en route charts, and the Chart Supplement.
Plain English
The FAA group that produces the official charts, approach plates, and flight information that pilots use to plan and fly.
Context Anchor
Seen in FAA handbook discussions about where pilots get current, official chart and procedure information for instrument flight.
Derivation
"Aeronautical" comes from the Greek aer (air) and nautes (sailor) -- literally "air sailing." So aeronautical information services means the office that provides the navigation information for sailing through the air.
Why Pilots Care
Accurate data from this service directly supports safe flight planning, in-flight navigation, and regulatory compliance; outdated information can lead to navigation errors or procedure deviations.
Intuition Check
Do not read “services” here as a help desk or an in-flight assistance service. In this context, it means an FAA source that provides official published aviation information.
Example Sentence 1
The instrument approach chart the pilot loaded into the avionics was published by FAA National Aeronautical Information Services.
Example Sentence 2
Changes published by FAA National Aeronautical Information Services are reviewed during preflight planning to confirm runway and procedure updates.
