ICAO chief stresses harmonised UTM priorities

One of international aviation’s most senior rulemakers has acknowledged the need for responsive regulatory frameworks to support the safe integration of unmanned air traffic innovations into the global network.

“Worldwide, RPAS and UAS technologies and operations have been evolving rapidly in recent years, spurring thousands of new entrants to the aviation sector and a multitude of new products and services requiring incorporation into the global aviation framework,” said ICAO secretary general Dr Fang Liu, concluding the UN aviation agency’s “Unmanned Aviation Week” series of events.

Acknowledging the new opportunities that this transformation offers, Dr. Liu said she recognized the safety and related risks they pose to legacy aircraft and operations, including the safety of people on the ground.

“ICAO’s member states anticipated these challenges when they mandated ICAO to develop new guidance for what are essentially domestic operations,” she said. “Their goal in this regard was to make use of ICAO’s co-operative and consensus-based decision mechanisms to realise practical and effective operational guidelines which could be codified for implementation in almost any urban environment.”

Dr Liu stressed that in order for the numerous socio-economic benefits of unmanned aviation to be optimised, regulators must work to craft and implement a well-structured and flexible regulatory framework, taking aviation’s longstanding safety performance prioritisation into consideration.

“Safety concerns such as collision with manned aircraft, the use of unapproved communications spectrum, and even the expectations of privacy for the citizens living among these intended operations, are all of great concern to governments today,” she noted. “And there are further issues we must address such as the functional interoperability we can expect to achieve with traditional air traffic management mechanisms, airspace design, and rules of the air for these new aircraft types, not to mention the location and types of operations relevant to UAS traffic management”.

Dr Liu further updated the Third RPAS Symposium on the contributions of states and organisations to this process, led by the Remotely Piloted Aircraft Systems Panel, with key outcomes being the adoption of new provisions across four Annexes to the Chicago Convention.

“I am very pleased to highlight in this regard that the Annex 1 provisions for the remote pilot licence were adopted last March by the ICAO Council, and that they are now available for voluntary use by states,” she said. “In line with our ongoing No Country Left Behind (NCLB) initiative, ICAO has also begun to assist states in their effective implementation of this new guidance.”

In her address to the subsequent DRONE ENABLE UAS industry symposium, Dr Liu emphasised the rapid advancements in small unmanned aircraft operations with relevant regional examples.

“According to industry studies, Chinese manufacturer DJI accounts for nearly 70 per cent of the non-military small UAS market today, and has seen revenues increase from just over 4 million to a staggering billion dollars in revenue between 2011 and 2015,” she remarked, adding that “The European market is expected to be worth over €10 billion or 78 billion Yuan annually in 2035, and over €15 billion or 178 billion Yuan annually by 2050.”

The ICAO chief said the predicted expansion of the unmanned industry will result in an equal number of aircraft operating simultaneously within congested metropolitan areas and airspace, noting that this will be a tremendous challenge for regulatory officials and airspace planners, and one which will require completely new approaches in terms of the management of air traffic.

“The UAS traffic management (UTM) concept which ICAO is now developing seeks to meet this challenge, head on,” she confirmed.

Referring to a request from states during ICAO’s 39th Assembly for the UN aviation agency to take a leadership role by assisting them in the development of harmonised international approaches to regulate small unmanned aircraft, Dr Liu noted the new progress expected at ICAO’s upcoming Thirteenth Air Navigation Conference next month at its Montreal Headquarters.

“Among the key objectives of the Conference will be the ongoing development of operational solutions and guidance to support the safe and co-ordinated development of aviation activities at low altitudes,” she said. “Special attention in this regard will be paid to urban and suburban environments, including those areas in and around airports.”

Dr Liu urged participants to focus their efforts on related concerns surrounding UAS operations over the high seas, which are increasingly carried out in activities such as oil platform and ship inspections, fisheries resource monitoring and compliance, atmospheric research and weather measurement, search and rescue, and security operations. “Significant work and bold thinking will be required. And we cannot simply ignore the existing aviation regulatory framework given its proven and indeed exemplary safety record for manned operations.”

She concluded her remarks by reiterating that “in such a dynamic and innovative area of activity, with such a continuous flow of emerging ideas and techniques, the UAS industry and regulatory communities must stay in close contact and work together to realise effective results.

ICAO’s Unmanned Aviation Week comprised the Third Global Remotely Piloted Aircraft Systems (RPAS) Symposium, held under the theme “from accommodation to integration,” and the ‘DRONE ENABLE’ Second Unmanned Aircraft Systems (UAS) Industry Symposium which focused on “transitioning from segregation to integration.”
