Which section lists air navigation obstacles?

Which section lists air navigation obstacles?

• A. en route section 5.4
• B. en route section 4.1
• C. meteorological services 3.3
• D. holding procedures 3.6

Answer: (A)

Air navigation obstacles are part of the route-planning data pilots use to ensure safe clearance along airways. In the En Route information, there is a subsection specifically dedicated to listing all air navigation obstacles. This makes it the place where you find the exact hazards that could affect routing and required altitudes. The other sections focus on weather services or procedure details (like holding), which do not provide obstacle listings. So the En Route section that covers obstacles is the correct source for this information.
