Where are RNAV requirements published?

• A. ICAO Annex 10
• B. FAA AIM
• C. EASA Part- FCL
• D. AIP Part 2 ENR4

Answer: (D)

RNAV requirements are published in the AIP Part 2 ENR 4. The Aeronautical Information Publication is the official source for operational data, and ENR 4 specifically covers en-route navigation requirements, including RNAV/RNP specifications and the equipment or performance criteria needed for various routes. This is the go-to reference for what navigation capability is required for planning and compliance on a given route. The other publications aren’t the source for these route-specific en-route requirements: ICAO Annex 10 deals with telecom and navigation standards at a high level, not published en-route RNAV rules; the FAA AIM is US-focused guidance; EASA Part-FCL concerns licensing.
