ENR 3.6 covers which topic?

• A. Holding procedures
• B. ATC services
• C. MORA
• D. Meteorological services

Answer: (A)

ENR 3.6 is about holding procedures. This section specifies how a holding pattern is designed and executed at a navigation fix, including the inbound and outbound courses, the direction of turns, leg lengths or timing, and speed considerations to manage aircraft safely in a published hold. Understanding these details helps ensure predictable aircraft spacing and orderly sequencing in en-route airspace. The other topics belong to different parts of the AIS: ATC services cover the broader air traffic control services, MORA pertains to minimum obstruction clearance altitudes for obstacle clearance, and meteorological services deal with weather information and observations.
