THE MARCONITRACK Aerodrome Approach Beacon Equipment is pre-eminent amongst "blind" approach systems. . Among its advantages are the following :-

AERODROME EQUIPMENT.
1.Marconi directional transmission which maintains maximum range performance with a fraction of the power otherwise required, thereby reducing considerably both first and upkeep costs.
2. If Marconitrack Marker Beacons are installed at an aerodrome for ZZ approach, a Main beacon can be added at a later date to form a complete "blind" approach system .

AIRCRAFT EQUIPMENT
3. The ZZ System of approaching an aerodrome can be used by aircraft fitted with Marconitrack equipment in conjunction with Marker beacons .
4. Receiver operates in conjunction with any ultra-short-wave approach beacon conforming to International Requirements .
5. Minimum of controls.
6 Subdivision of equipment into units thereby facilitating installation in any aircraft. Only the last two items at the right of the illustration need be installed in the cockpit.
7. Unique provision for changing from one to another of six different frequencies simply by the turn of a switch.
