Mandatory broadcast zone (MBZ)
A mandatory broadcast zone is an area normally established at a busy uncontrolled aerodrome, or airspace that has intensive tourist operations.
An MBZ requires a pilot to broadcast position, altitude, and intentions reports on a specified frequency on entry, when joining an aerodrome traffic circuit, prior to entering a runway, and at specified regular intervals as indicated on aeronautical charts when operating within the MBZ.
As an extra safety measure, landing or anti-collision lights must be switched on, if fitted.
Radio frequencies are on the appropriate charts.
