ENR 5.4 covers which topic?

• A. Air navigation obstacles
• B. Navigation aids en-route
• C. ATS services
• D. Meteorological services

Answer: (A)

Air navigation obstacles along en-route flight paths are what ENR 5.4 covers. This part of the AIP provides official data on obstacles—like towers, buildings, mountains, or other tall structures—that pilots must consider when planning and executing routes. It includes details such as the obstacle’s location, height, and reference points, helping you determine safe altitudes and ensure obstacle clearance along the en-route portion of the flight. The aim is to give reliable, up-to-date obstacle information so that route planning and actual flying can avoid any potential hazards. Other topics like navigation aids en-route, ATS services, or meteorological services are covered in different ENR sections, not in ENR 5.4.
