AIPNZ Volume 1, the radio procedures, requirements, and functions associated with:
(a) UNICOM; (Universal Communication)
- is an Air/Ground communications facility
- at certain uncontrolled aerodromes normally within a Mandatory Broadcast Zone.
- providing limited known traffic and weather information on request.
- is not an air traffic service staffed by the Airways corporation, so is deemed unattended.
There is currently only one UNICOM in New Zealand – at Ardmore aerodrome, where the service is provided by the airport company.
The Use of Frequency 119.1
The frequency 119.1 MHz is for unattended aerodromes that do not have a designated frequency.
It is for use within 10 NM of these aerodromes – use outside this can compromise appropriate joining and circuit communications.
With this in mind, it should not be used as a general chat channel.
The meaning of light signals used by ATC.
When performing a 'radio check' to ATC, Unicom or traffic, a scale of 1-5 is used to check readability.
