ADS-B receivers are normally installed by Airservices on their radio towers. According to ERSA 122.4 can be received on the ground at MNG and the 5000 foot ADS-B coverage diagram includes the MNG area; I do not, however, know what ADS-B coverage is available on the ground or below 5000 feet.
If the 122.4 mast does not have an ADS-B receiver them it would be very cheap and straightforward to install one.
Alternatively Aireon offers a space-based ADS-B service via Iridium satellites that is compatible with current ATC systems and can provide a 5NM separation standard. This means that with some engineering and signing a contract Airservices can offer IFR separation services over the whole continent.
That would however require an expansion in the number of ATC positions in the two ATC Centres, something that, under our system, somebody has to pay for.
Given the very explicit rules about training flights in the MNG area listed in ERSA I am surprised that there is no CTAF. Radio instructions contrary to the legislated requirements in CAR166 are below and it all seems to take place on the area frequency!
- The MNM radio broadcasts are taxiing, entering, departing: Inbound, Joining, Base and Final with position, altitude and intentions.Note:
- Pilots must respond to radio requests from other TFC for their intentions, position or altitude.
- Base/Final broadcast is to include a nominated ACFT landing sequence number, determined by your position behind preceding airborne ACFT (e.g. Warrior ABC final 23 touch and go number 2
If there was an MBZ or CTAF then there would be nothing to stop anyone, Mangalore airport, the local flying school or a bored retired pilot/ATC setting up a UNICOM. The radio has to be licensed by ACMA and the operator needs a flight radio operators certificate unless they hold a pilot's licence. They can also obtaina weather observers certificate from the BoM and make observations for pilots. There are also no regulations prohibiting the use of Flight Radar 24 by a UNICOM operator, the AIP even allows limited traffic information. Perhaps industry should determine it's own safety instead of waiting for the Government?
