ADS-B 2021

With space-based ADS-B now being used in areas such as the North Atlantic, controllers can see aircraft live in areas of the world using non-radar procedures since the dawn of aviation.  The airspace in which an aircraft can operate without ADS-B equipment is becoming increasingly thin and will continue to shrink over the next few years.

The following is an overview of what ADS-B is, which countries already require ADS-B, and those who have upcoming mandates:

1. Understand ADS-B

ADS stands for “Automatic Dependent Surveillance” – a surveillance capability used for tracking aircraft. There are two commonly recognized types of ADS: ADS-B (broadcast) and ADS-C (ContRact). ADS-C is broadcast on a one-to-one relationship between the reporting aircraft and the ground facility. On the other hand, ADS-B operates in a broadcast mode. The aircraft reports position and ground speed information regularly and at a much higher frequency than for ADS-C. The advantage of ADS-B is that any appropriately equipped ground facility, or other aircraft, can intercept position reports.

2. United States

ADS-B is required when operating overall 48 continuous states, within airspace at or above FL 100 (excluding airspace from 2,500 ft AGL). At or below FL100 ADS-B will be required; 1) While operating within class B or C airspace. 2) While operating within 12NM of the coastline in the Gulf of Mexico, at or above 3,000 ft MSL.

ADS-B is now required when operating overall 48 continuous states, within airspace at or above FL 100 (excluding airspace from 2,500 ft. AGL). At or below FL100 ADS-B will be required:

  1. While operating within class B or C airspace.
  2. While operating within 12NM of the coastline in the Gulf of Mexico, at or above 3,000 ft. MSL.

Requirements for areas outside the 48 Contiguous States can be found in the FAA Notices to Airmen.

ADS-B for 2019

ADS-B Exemption

ADS-B is required when operating over the U.S. as of Jan. 1, 2020. However, aircraft without the necessary ADS-B capabilities can still operate in U.S. airspace with a single-use route deviation authorization obtained through the FAA’s ADS-B Deviation Authorization Pre-Flight Tool (ADAPT).

To accommodate requests for authorization to deviate from this rule, the web-based tool known as ADAPT was created. As stated in an FAA policy statement (84 Federal Register 12062 dated April 1, 2019), ADAPT is not intended to be used for regular or routine operations by non-equipped aircraft, and your use of ADAPT appears to be regular and/or routine.).

Suppose the FAA denies your requests due to regular and/or routine use. In that case, a one-time authorization may be requested for actual ADS-B equipment installation or ferry of aircraft. 

ADAPT facts:

  • Applies to U.S. airspace route segments only
  • Only valid for a single route
  • Applications can be submitted 24 hrs. to 1 hr. in advance of departure
  • Authorizations are only valid within a +2 hour window of approved ETD

3. Australia

ADS-B is required for all IFR operations at all flight levels over continental Australia, the Arafura Sea (bounded on the north by airway B598), the Great Australian Bight (bounded on the south by airway Q27/L513), and the Bass Strait (bounded on the east by airway H20 and to the southwest by L513). More information can be found on AIP GEN 1.5 | CAO 20.18, 82.1, 82.3, and 82.5 | CASA 61/14

4. Europe

ADS-B is mandated for all aircraft.  Requirements apply only to instrument flight rule (IFR) flights and only for aircraft with a maximum takeoff weight (MTOW) of 5700 kg (12,566 lbs.) or greater and/or max cruising true airspeed (TAS) greater than 250 knots (kts).

Transitional Phase

The transitional phase ends on June 7th, 2023.  During this period, an aircraft can be exempt from the mandate based on one of the following.

  • The first individual Certificate of Airworthiness was issued on or after June 7th, 1995 and before December 7th, 2020 and
  • The operator has established a retrofit program prior to December 7th, 2020 that demonstrates compliance prior to June 7th, 2023 (Reference EU No 1207/2011, Article 5, part (c)) and
  • The aircraft has not benefited from EU funding for the retrofit implementation (Reference EU No 1207/2011, Article 5, part (c)).

Exemptions

An aircraft will be exempt from the mandate if they meet one of these criteria.

  • Individual Certificate of Airworthiness first issued before June 7th, 1995, OR
  • Flight purpose is for maintenance or export, OR
  • Operation will cease by 31-OCT-2025

If an aircraft meets any of the exemptions above, enter EUADSBX into the Item 18 SUR/ field of their FPL.

For more information, see (EU) No 1207/2011 and (EU) No 1028/2014 and (EU) 2017/386 and (EU) 2020/587, the latter 3 are amendments to (EU) No 1207/2011 | EASA AMC | ADS-B Europe

Equipment versions

All mandates in effect currently require your ADS-B equipment to meet the requirements for 1090ES (1090 MHz), while some areas (USA) also allow 978 UAT (978 MHz) equipment to be used.  Be sure you have the correct version to operate where you are going.

Tips when traversing regions with ADS-B requirements

Become familiar with ICAO FPL equipment and capability codes (Items 10a/b and Item 18) as well as your performance-based navigation (PBN) codes to help prevent misunderstandings with air traffic control (ATC) while in flight. Know which codes apply to the specific operation. Remember that codes filed in the FPL should represent not only aircraft equipment and capabilities but also those crew members covered by necessary training, authorizations from state of registry, and working equipment.

Conclusion

Many ADS-B mandates will come into force in 2020. Remember that even though some countries do not currently have any ADS-B mandates or any proposals for mandates, there is still quite a bit of ADS-B coverage out there. Those aircraft not equipped with ADS-B can still potentially run into situations as you are less equipped than those around you. Keep this mentality in mind while flying these days … “better equipped, better served,” as it is no longer just first come, first served.
