Definition
On an IFR en route low altitude chart, a labeled box associated with a navigation aid (NAVAID) that displays the facility's name, frequency, three-letter identifier, and Morse code identification. It allows pilots to confirm they are tuned to and receiving the correct station.
Plain English
A small information panel printed next to a navigation station on the chart. It shows the station's name, the frequency to tune, its short letter code, and the Morse code dots and dashes you should hear when you've tuned it correctly.
Context Anchor
Seen on IFR en route low altitude charts next to navigation facilities and other charted items that need a compact label.
Why Pilots Care
Allows immediate verification of the correct navaid and prevents tuning errors during navigation.
Intuition Check
Do not read “identification box” as just any label on the chart. In this context, it means the specific boxed chart information used to identify a facility or item, often with operational details such as frequency or identifier.
Example Sentence 1
Before tracking the airway, the pilot referenced the identification box on the chart, tuned 113.5, and listened for the Morse code to confirm the VOR.
Example Sentence 2
On the en route chart the identification box next to the symbol listed the Morse code dots and dashes for the navaid.
