Which AIP section contains obstacle data en-route?

Which AIP section contains obstacle data en-route?

• A. ENR 5.4
• B. ENR 5.3
• C. ENR 4.4
• D. GEN 2.4

Answer: (A)

Obstacle data en-route is found in the ENR part of the AIP, in the subsection that lists obstacles along the flight path. This is the section that provides the elevations and coordinates of obstacles that pilots must consider when planning and flying en route. The ENR portion is specifically for information used during the flight between aerodromes, so obstacle data that affects en-route navigation belongs here rather than in the general information or in other ENR subsections that cover different topics.
