Normal Aviation and unmanned plane communities set to learn from fund to subsidise digital conspicuity gadgets – Drones Information


Thanks to funding from the Department for Transport (DfT) aimed at promoting the adoption of EC in the UK General Aviation (GA) and Unmanned Aircraft Systems (UAS) systems, discounts of up to £ 250 are now available on new electronic Devices (EC) available. Communities.

The CAA distributes the funds through a rebate program open to requests for devices purchased before February 28, 2021 (or until the funds are used). Those who meet the requirements can apply for a 50% discount on the cost of an EC device up to a maximum of £ 250 (including VAT) per applicant.

Rob Bishton, CAA Group Director for Safety and Airspace Management, said “See and Avoid” remains the basic means of avoiding collisions in Class G airspace. Electronic alert devices, deployed with an understanding of their advantages and disadvantages, can be an important one Play a role in improving situational awareness and reducing the risk of mid-air collisions in Class G airspace and airspace violations. Looking ahead, EC interoperable systems will also play a role in the ongoing modernization of the UK airspace structure. and enable the safe and efficient integration of UAS operations into other airspace users. “

The Department of Transportation (DfT) has provided funding to promote the adoption of Electronic Conspicuity (EC) in the UK communities of General Aviation (GA) and Unmanned Aircraft Systems (UAS). The CAA distributes these funds through a discount system.

The program can be requested from October 5, 2020 to March 31, 2021 (or until the funds are used). Those who meet the requirements can apply for a 50% discount on the cost of an EC device up to a maximum of £ 250.00 (including VAT) per applicant. We anticipate up to 10,000 discounts will be available.

What are the requirements to apply?

  • Financing is only for hand luggage or aircraft equipment. Floor system components are not qualified for this scheme.
  • Applicants can apply for a one-time 50% discount – up to £ 250 – on purchased EC equipment.
  • Only devices purchased between October 1, 2020 and February 28, 2021 are eligible for a discount.
  • You must provide proof of purchase.
  • You must have at least one of the following UK pilot licenses (UK or EASA Part FCL):
  • Private pilot license (PPL)
  • Commercial Pilot’s License (CPL)
  • National PPL (NPPL)
  • Glider pilot’s license (SPL)
  • Balloon pilot license (BPL)
  • Light Aircraft Pilot’s License (LAPL)

Or you are a registered member of the British Hang Gliding and Paragliding Association (BHPA) or the British Gliding Association (BGA).

  • Alternatively, if you are a UAS / UAV operator, you must have a permit issued specifically for you by the CAA (i.e. a permit, exemption, or “operating permit”). It does not contain general exceptions, authorizations or permits that are aimed at a broader and unspecific group of operators

What equipment is included in this discount program?

We recognize that there are a number of EC solutions on the market that manufacturers and municipalities have developed for their own needs.

The main equipment that can be used on an aircraft for currently available EC purposes (and against which a refund can be requested) includes:

  • ADS-B Out-capable transponder including GNSS position source (mode S ES activated).
  • ADS-B Out-capable transponder without GNSS position source (mode S ES)
  • Certified GNSS source for Mode S ES transponders (including a GNSS position source according to the recently published AIC2019Y141, example Trig TN72)
  • Power Flarm
  • Pilot Aware Rosetta
  • Sky echo 2

We will consider requests from device manufacturers for alternative or newly developed devices to be added on a case-by-case basis.

What do I have to consider before buying and using EC devices?

“See and Avoid” is the basis for Visual Flight Rules flying in the UK. EC devices can improve situational awareness for pilots, but do not replace the fundamental role of “see and avoid”. Pilots using EC devices should be aware of their functionality and know what they can and cannot do. Devices are not always interoperable with each other. This means that users of one type of device may or may not be electronically visible to one another, have different reliability and accuracy standards, and can use different parts of the radio spectrum to transmit signals.

The DfT and CAA do not recommend any particular device to pilots, but recommend all pilots understand and consider the functional advantages and limitations of an EC device so that they can make informed decisions about the level of trust placed in the information provided can become them.

While not a definitive list, the following table describes the most common EC technologies currently in use, a full understanding of the interoperability between them and the certified ones.

Warning beacons Which traffic receivers can they see?
ADS-B-In devices (certified) ADS-B in Rx Airborne Collision Awareness Systems (ACAS) Pilot Aware Rosetta (PAW) Power FLARM Sky Echo 2 (SIL-1 device) CAA CAP 1391 approved
ADS-B Out transponder certified GPS Yes Yes Yes Yes Yes Yes
ADS-B-Out transponder not certified GPS (Surveillance Integrity Level (SIL) 0) No * 2 Variable * 4 Yes Yes Yes Yes
Power FLARM No No No Yes, 1 Yes Yes 3
Pilot Aware Rosetta (PAW) No No No Yes No No
Sky Echo 2 (SIL-1 device) CAA CAP 1391 approved Yes Variable * 4 No Yes Yes Yes
* 1) Depending on the proximity to the ground infrastructure
* 2) Certified traffic receivers normally exclude reports from transponders and beacons that are set to SIL 0
* 3) A FLARM decoding license and a suitable display are required for the new development
* 4) Transponders or beacons with a non-certified GPS (source integrity level 0) may not be recognized by a certified ADS-B in the device. Source health level 1 and higher can be seen.
In the table above, the term “certified” means a device that has been tested to meet ICAO standards and is operated in the aviation spectrum.

In parallel with the grant program, work on a long-term strategy for the EC in the UK will continue. Surveillance technology will evolve rapidly and we, together with the DfT, are open to researching and introducing new technologies. Applicants should be aware that, as with other technologies in any sector, there is no guarantee that a device purchased today will meet future EC requirements.

How do I apply?

Applications can be submitted via our online stakeholder portal from October 5, 2020. You will be asked to register in the CAA online portal and then to submit an online application form.

What is electronic abnormality?

Electronic Conspicuity (EC) is an umbrella term for the technology that enables pilots, unmanned aircraft users and air traffic services to better understand what is happening in the surrounding airspace. EC includes the aircraft and unmanned systems equipment that sends the information, as well as the supporting infrastructure to support collaboration. Examples of EC are transponders in the air, air traffic data displays, ground antennas and satellite monitoring services. The information generated by this can be presented to pilots and air traffic services visually, acoustically, or both to provide them with information about other traffic in the vicinity. This strengthens the principle of “see and avoid” by adding the ability “know and recognize”. To be most effective, 100% of users with compatible EC devices must work in a particular block of airspace and be recognizable by others.

The EC can play an important role in supporting the UK’s Airspace Modernization Strategy (AMS) in three key areas:

1. Enable the ongoing modernization of the UK’s airspace structure and route network.

2. Contribution to reducing the risk of collisions in the air in class G and violations of the controlled airspace.

3. Enable the safe and efficient integration of unmanned aircraft.
