Project Claire

2. Project CLAIRE
 Integrated RPAS Demonstration Activities
 Demonstrate how to integrate RPAS into non-segregated airspace in a
multi-aircraft and manned flight environment
 Focus on filling the operational and technical gaps identified
 Provide synergies, risks and opportunities with the overall SESAR
programme
 Project CLAIRE
 Up to a 24-month programme aimed at demonstrating current RPAS
capabilities
 Key aim is to operate RPAS within a non-segregated mixed traffic
environment & demonstrate ATM procedures that need to be applied
within different classes of airspace
 Experiments, real-time demonstrations and potential real-world flight
trials

3. 3 / Key Objectives
 Key Objectives
 Establish the regulatory, operational and technical
infrastructure which enables UAS flight testing in a mixed
air traffic environment
 Demonstrate airport surface operations capability
including interaction with other traffic on the surface as
well as ground obstacles
 Demonstrate take-off and landing without impacting airport
throughput
 Quantify minimum performance requirements for
integration such as speed, climb/descent and turn
performance
 Incremental Approach to airspace access
 4 scenarios – increasing complexity
 Watchkeeper
● Seven year programme
● First UAS Certified Airworthiness Platform
• CS23, STANAG 4671 – High level of Safety airworthiness
● Number of flying hours: >1000

4. 4 / Initial Findings 1/3
Exercises 1a & 2 complete – Results
consistent
 Normal RPAS Operation:
 Unmanned Aircraft made little or no difference to ATM operations
 Control Station handovers
● Seamless, but RPAS pilots should ensure that handovers do not
coincide with sector handovers
● Should be as transparent as possible to the ATCO
 Speed differentials for some of modelled RPAS compared to
commercial aviation posed more of a challenge but well within ability
of ATCOs
 Long endurance RPAS could be held until a gap appeared in arriving
traffic
 R-T for normal operation was the same as manned aviation
 For lower performance RPAS, runway occupancy times were
regarded as too long
 Operational transponder essential

5. 5 / Initial Findings 2/3
 For Abnormal Events and Situations:
 Airport emergency procedures may need to be modified
 Increase in ATCO workload (consistent with manned aviation)
 Slow speed of RPAS was considered positive and negative
● Negative: Not consistent with the speeds of most manned aircraft
● Positive: Nothing happened quickly – time to react
 Flight of RPAS was considered more predictable than manned
aviation
 Backup communication between ATSU and RPAS Pilot worked well
● In manned aircraft, flight crew can be distracted and less predictable
 Handovers between sectors worked well

6. 6 / Initial Findings 3/3
 Contingency Planning and Management:
 Five types of information identified
● Lost Link routes
● Transition Points for Lost Link Routes
● Diversionary Sites
● Transition Points for Diversionary sites
● Significant Times associated with Lost Link Route
 How much information is shared with ATC
● In Advance
● During Flight
● Following an Unusual Event
 Need to agree phraseology

7. 7 / Regulatory Activities
 Project CLAIRE output will support the better understanding of the European
regulatory framework to assist in the integration of RPAS into non-segregated
airspace through
 The capture of safety related elements, in order to support to the development of safety
objectives for airworthiness (i.e. to mitigate the risk to persons on the ground)
 Feedback from flight demonstrations in non-segregated controlled airspace (classes A, B and
C) to RPAS flying under General Air Traffic (GAT)
 Understanding of Detect and Avoid conflict detection, resolution and monitoring functions to
cope with co-operative intruders (i.e. equipped with an ATC transponder)
 Preliminary exploitation of System Wide Information Management (SWIM) by RPAS, in
particular enabling controller-pilot data link communications via ground network
 Provision of data to support the EASA development of a dedicated certification specification
(CS-UAS) for RPAS
