What significant change was added to the Aeronautical Information Manual in 2020 regarding NAVAIDs?

The significant change added to the Aeronautical Information Manual in 2020 regarding NAVAIDs is the introduction of updated Standard Service Volumes (SSV) for VOR (VHF Omnidirectional Range) and DME (Distance Measuring Equipment). This change reflects an effort to clarify and standardize the service volumes that define the maximum operational range and coverage patterns of these navigational aids, which are critical for pilots' navigation and situational awareness.

Understanding the updated SSV is vital for pilots as it directly affects how they plan their routes and the reliability of the navigation aids they rely upon in different flight scenarios. These service volumes provide information on the operational limitations and the reliability of the navigational aids, ensuring pilots can make informed decisions during their flight operations.

The other options discuss various aspects of navigation and operational procedures; however, none directly pertain to the significant change regarding NAVAIDs documented in the Aeronautical Information Manual in 2020.
