The Civil Aviation Authority is proposing that
if you want to fly in controlled airspace at any altitude after 31 December 2021, you will need to be
ADS-B OUT equipped.
NSS also propose that if you want to fly in controlled airspace at any altitude after 31 December 2021, you will also need to be ADS-B OUT equipped.
The ADS-B OUT mandates will only apply to controlled airspace, as it’s required there for aircraft separation.
However, even if you don’t fly in controlled airspace, there are benefits to equipping with ADS-B OUT:
Existing Mode S transponder
If you have a Mode S transponder, you’ll need to check with your avionics shop to see if it is ADS-B OUT capable. Not all Mode S transponders are ADS-B OUT capable. Some Mode S transponders can be upgraded to enable extended squitter functionality.
If you are upgrading your Mode A/C transponder, we strongly suggest you buy an ES capable Mode S transponder, even if you don’t currently fly in controlled airspace. You can buy a transponder first and add a GNSS position source later. Make sure that the transponder and the GNSS receiver are compatible.
Cheaper ADS-B systems overseas – buyer beware
New technologies are becoming available, particularly in the area of GNSS receivers. Please check the fine print and make sure the transponder you’re considering broadcasts on 1090 MHz, not 978 MHz. The advertising information is not relevant to New Zealand. UAT will not work in New Zealand.
As we consider options for the proposed mandate for ADS-B in all controlled airspace, we are considering whether and how we can provide for 1090 MHz ADS-B OUT systems that are cheaper and/or lighter. Any new technologies will need to meet the performance standards set in the NTC 91.258.
All-in-one ADS-B solutions
You can now buy ADS-B systems that include the transponder and GNSS receiver in a single unit. These are ‘all-in-one-box’ ADS-B systems. However, installing an all-in-one system still involves a modification. They can be cheaper than buying and installing the separate components, and you will have the assurance that the transponder and GNSS receiver are compatible. Some all-in-one systems include ADS-B IN and a touchscreen display.
The GNSS receiver on the all-in-one solutions cannot be used for navigation when operating under Instrument Flight Rules (IFR).
You can discuss all-in-one ADS-B solutions with your avionics supplier.
The process for installing ADS-B on your type certified aircraft is described here.
Please talk to your Part 149 organisation about the process for installing ADS-B on a microlight, glider or amateur built aircraft.
Owners of light sport aircraft should talk to their OEM regarding getting ADS-B Equipped.
