Which AIP section provides FIR boundary details?

Which AIP section provides FIR boundary details?

• A. ENR 2.1
• B. ENR 2.2
• C. ENR 1.0
• D. ENR 3.4

Answer: (A)

FIR boundaries are published in the en-route information section that focuses on the Flight Information Region and the associated airspace limits. ENR 2.1 is the part that specifically includes the official FIR boundaries and related en-route details, making it the authoritative source for where Indian airspace boundaries and cross-border coordination are defined. General information in ENR 1.0, or topics covered in ENR 2.2 or ENR 3.4, do not provide the dedicated FIR boundary details, so ENR 2.1 is the best place to look for this information.
