Operators of foreign registered aircraft: ADS-B
On this page
This guidance information is for operators of foreign registered aircraft on the new requirements for Automatic Dependent Surveillance-Broadcast (ADS-B) installation.
|6 June 2020||ADS-B Instrument CASA EX 113/16 expired. ADS-B is required for operations in Australian airspace under the IFR|
Are foreign registered aircraft required to be fitted with operational ADS-B when operating into, within, and out of Australian airspace?
ADS-B Transmitting equipment is required to be fitted, and operational, in accordance with CAO 82.5 Appendix 4, and Australian AIP GEN Section 6 ATS Surveillence.
ADS-B may be inoperative in accrodance with the MEL without the need of CASA approval.
If an MEL is not available then operations may be conducted without ADS-B Transmitting equipment but only with special approval from CASA. Approval with short notice from CASA is unlikely as the approval also requires specific approval and assessment from Airservices due to operational restrictions.
The following provides guidance on the requirements for the carriage of ADS-B Transmitting equipment when conducting operations within the Australian FIR under the IFR.
CASA Instrument 113/16 Authorisation — foreign registered aircraft operating without ADS-B transmitting equipment dated 22 November 2016 expired at the end of 6 June 2020.
All foreign registered aircraft operating under the IFR, engaged in commercial international air transport within Australia are now required to be equipped with operational ADS-B equipment unless otherwise permitted in accordance with Civil Aviation Order (CAO) 82.5 Appendix 4, clause 8.
It is an international mandate (e.g. FAA and EASA) that all aircraft are equipped with operational ADS-B equipment in order to provide appropriate separation and surveillance capability.
All FATAOC holders and Section 25 Non-Scheduled permission applicants, in accordance with CAO 82.5 Appendix 4, will be required to have operational ADS-B equipment fitted to their aircraft for the period of time that the aircraft is expected to be within the Brisbane and/or Melbourne FIRs.
CAO requirements: Prior to departure from a foreign or Australian port:
An operator that has an aircraft equipped with ADS-B that is inoperative, prior to departure, for a flight that is expected to operate within the Brisbane and/or Melbourne FIRs, may carry out the flight in accordance with specific requirements in CAO 82.5 Appendix 4 clause 8 and the Australian AIP GEN 1.5, Section 6 ATS Surveillance, para 220.127.116.11.
CAO 82.5 Appendix 4 clause 8 includes two main options for operations with inoperative ADS-B. The preferred, and least time consuming, method of approving such flights is for the operator to have a Minimum Equipment List (MEL), approved by the State of the operator, that permits dispatch, and subsequent operations, with an inoperative ADS-B.
For operations into Australian territory the period of unserviceability cannot extend past 3 days from the time the unserviceability was noted, i.e. unserviceability entered into the technical log, or equivalent.
A flight may depart without ADS-B transmitting equipment, or with inoperative ADS-B transmitting equipment, in accordance with the following two options:
- With written authorisation from CASA for the operation of the aircraft without the ADS-B transmitting equipment, or
- The aircraft is equipped with ADS-B but the ADS-B transmitting equipment is unserviceable for a flight, and each of the following applies:
- the flight takes place within 3 days of the discovery of the unserviceability.
- the unserviceability is a permissible unserviceability as set out in the MEL as approved by the NAA of the State of registration of the aircraft; and
- ATC/ (Airservices Australia) clears the flight before it commences despite the unserviceability.
The operator would need to apply directly to CASA, International_ops@casa.gov.au for an authorisation to conduct operations without ADS-B transmitting equipment.
This process is likely to be very time consuming and will be problematic for an operator trying to maintain scheduled operations while waiting for the approval process to be administered by both CASA and Airservices Australia.
In addition to the CASA authorisation, the operational restrictions required by Airservices Australia may be considerable due to significant route/flight level and other operational ATC restrictions.
It is not recommended that aircraft, without MEL coverage for inoperative ADS-B transmitting equipment, are scheduled for operations to Australia.
The preferred and a straightforward option for operations with inoperative ADS-B transmitting equipment. In order to take advantage of this option, it is required for operators to update their MEL’s by including a specific section related to inoperative ADS-B transmitting equipment.
Prior to any flight intended to operate within the Brisbane and/or Melbourne FIR with inoperative ADS-B transmitting equipment the operator is required to contact Airservices Australia for approval (clearance). The first FIR to be entered by the flight should be the FIR contacted for approval. The telephone contact numbers for the relevant FIR’s are found in AIP GEN 1.5 Section 6 ATS Surveillance page -13. At the time of writing the phone numbers are Brisbane FIR – 07 3866 3224, Melbourne FIR 03 9235 7420, reference to the specific Australian AIP sections are recommended for up to date details.
CASA is not required to be notified if the flight is dispatched in accordance with the MEL,
Reference to the specific section of CAO 82.5 Appendix 4 should be made prior to any flight with an inoperative ADS-B. The CAO 82.5 can be found on the current rules page.
Airservices Australia processes for approving aircraft with Inoperative ADS-B
Airservices Australia have processes in place for the Duty Operations Manager (OM) in either Brisbane or Melbourne to approve flights of aircraft with Inoperative ADS-B equipment. For ADS-B unserviceability, AIP GEN 1.5 para 18.104.22.168 requires pilots to contact Airservices Australia prior to departure to obtain an approval. As the aircraft will most likely be operating a non-surveillance aircraft in surveillance airspace, there are a number of restrictions that will be imposed on the aircraft to assist ATCs to manage it with other traffic.
The current Airservices Australia restrictions placed on the operations with inoperative ADS-B equipment are as follows:
- Approval is applicable for one flight only;
- The aircraft must flight plan below FL290, unless otherwise advised;
- Clearance to operate is at the discretion of the ATS controller and will be subject to operational conditions;
- ADS-B equipped aircraft will be given priority; and
- The ATS flight plan Field 18 must be annotated with;
RMK/ATC APPROVED NIL ADSB, in addition add the preferred fight level.
ADS-B failure during flight:
If ADS-B equipment fails in flight, OEM and operator non normal procedures and AIP procedures are required to be followed. ATC should be advised as soon as possible.
Due to operational conditions it may be necessary for Airservices Australia to amend the current flight plan with route and/or flight level changes. ATC makes clearance decisions subject to prevailing air traffic and operational conditions at the time of the flight.
The operator must take into account extra fuel requirements if the original flight planned levels cannot be provided due to other traffic requirements. It is possible that flight at or above FL290 may not be available for aircraft with inoperative ADS-B equipment.
From 7 June 2020 all applications for FATAOC initial or renewal, or application for a Section 25 Non Schedule flight approvals, will be assessed taking into account the requirement for the aircraft to be equipped with operative ADS-B equipment. Aircraft that are not fitted with ADS-B equipment may not be permitted to operate into Australia due to ATC restrictions. If the flight is authorised, then subsequent ATC restrictions may make the flight un-viable due to fuel constraints.
