Query string parameters of the ibonav.aero ATC pages. These pages need a ibonav.aero member login with an ATC role.

ATC Broadcasts (/atc-broadcasts)

Parameter Value Description
listen page identifier Opens the broadcast page with this identifier (case-insensitive).
  • The identifier is the page's own key, not always an ICAO indicator: most pages use one (ltac, ltaa), some use a name (trnc, other-channels). The page's search box lists all identifiers.
  • Without listen the page shows the page selection. An unknown identifier shows "Page Not Found".
  • Audio never starts by itself; the viewer presses Play.
