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 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.
Aircraft without an operable radio must not enter an MBZ unless another accompanying aircraft in formation can broadcast the required reports on their behalf.
