Industry News World ATM Congress 2021

On the agenda were an extraordinary number of presentations and panels, with 225 speakers in all. Spain's king, Felipe VI, opened the WAC on the morning of 26 October. In his address, he welcomed his fellow pilots (he is a pilot himself) and the aviation professionals from over a hundred countries.

More noticeable however were those that were absent from the event: the USA was missing, despite some stands had been reserved as shown on the maps that were distributed at the entrance. They obviously still faced travel restrictions. EUROCONTROL, SESAR and the European commission were also absent, which left a big vacuum in the European arena. All this empty space was filled by drones in all different shapes, sizes, functionality and purpose. Some had little or no relevance to ATM, as they were mainly designed for pure military or police operations. Many start-up companies and universities showed off their prototypes, with some blissfully unaware of personal safety regulations. Most will hopefully never be certified to carry passengers or to be operated anywhere near people.

The interesting bits as usual are in the various presentations, debates and panels. A huge number this year, possibly explained by the fact that there was no central CANSOATCA conference unfortunately.

To get a feel for the new trends, I attended four or five of these each day. Although their titles invited participation, attendance was generally low and many speakers seemed quite unprepared. Some notable exceptions were Frequentis, who presented their views on remote towers with Denmark’s ANSP Naviair. They outlined their plans for a remote tower and approach at Billund airport. All in all, interesting although I was told that the local controllers are not really in favour.

A similar interesting presentation was by Germany’s provider DFS on their plans to create a remote tower in Munich, a first for a large international hub airport. They also mentioned during the presentation that contrary to what they always have said in the past, they are now seriously studying the possibility for a single controller to control up to three different airports at the same time! The genie is finally out of the bottle. On the technical side, the arrival of so many drones near airports has created the need to detect those drones early enough to ensure the safety of Commercial traffic. A paper from the UK Airprox board indicated that since 2017, the average airprox number between a drone and a civil aircraft in the UK alone is between 10 and 16 a month. Some very close ones too, and unsurprisingly all are happening below 3000Ft and within 5-6 NM from the airport. Various solutions are proposed, One from Aveillant, a UK company belonging to Thales, which developed what they call a Holographic radar, a small L- Band (low frequency) radar, fixed antenna, range of 7,7 Km and 3000 Ft, can detect very small flying objects, even small birds. It has a AI software that determine if it is a drone or a bird as the Drone Rotors give a very distinctive signal, and can send warnings to ATC in real time.

A totally different approach was made from the German company HENSOLDT: they developed a passive radar based on the reflexion of Radio and Television broadcast signals. Any moving (flying) object disturbs these electromagnetic waves and the system can detect and locate it. The system called Twinvis has a range up to 300km, but practically and ideally 100 km with an accuracy of 100m. It is low power and as it only listens, it cannot be jammed. It can detect small UAVs as well as stealth z DFS Munich Remote Tower presentation by Klaus-Dieter

military aircraft and interact with ATC.

Finally, a Czech company called RETIA developed a mini radar (X-band i.e. very short wavelength). Named ReGuard, it is aimed at detecting drones at a typical range of up 10 Km up and 9000 ft with great accuracy. The whole system, antenna and control box are portable and low weight. The passively cooled transistor antenna is somewhat futuristic.

From the many drones exhibited during the show one stood out as very promising. A twin-piston engine amphibian developed in the Canary Islands for the purpose of search and rescue and delivering goods to ships. This is a very large drone: empty, it weighs 2,2 ton and it has a maximum take-off weight of around 4000 Kgs, meaning it can carry some 1,5 tons of goods. It can fly up to 24 hours in surveillance mode or 11 hours with 900kg payload at 120 Kts. It can fly up to 24.000ft. The company stated that they have already built 12 of them.

On Thursday 28 October, the last day of the show, participants were invited to go to Madrid’s Cuatro Vientos Aerodrome, the oldest airport in Spain with its original signalling tower dating back to 1919. At this historic airport, they demonstrated what was referred to as “the sky of the future”: a single airspace where unmanned vehicles fly together with traditional aviation. They claimed that for the first time anywhere in the world, an active airport airspace accommodated civil and military aircraft together with drones at the same time. The day ended with a spectacular light and sound show with a swarm of 100 synchronised drones.

The next WAC 2022 will again be held in Madrid, slightly later than normal from 21 to 23 June 2022.

The plan is to return to the normal dates in 2023: 7-9 March. y
