1 Airspace Infringement Survey 2007 Vladimir Grigorov, COMPASS IS 24 January 2008, Brussels

2 Why the survey? Occurrence reports do not enable in-depth analysis of causal and contributory factors! To ask those, who have experienced the risk, what could be made to prevent or reduce the likelihood of infringements! Pilots opinion and suggestions are considered paramount in establishing correct and efficient risk reductions measures!

3 General parameters Survey conducted Jul 2007 Sep 2007 Six focus groups: Bulgaria, Germany, Netherlands, Norway, Portugal and UK Pilots from 24 European states Questionnaire results: Total of 1076 questionnaires 552 complete questionnaires 473 analysed questionnaires

4 Major findings Aeronautical information provision not meeting GA needs Airspace complexity Inadequate communication between pilots and ATC/FIS Inefficient pilot navigation skills and use of available technology Quality and scope of ATS (ATC/FIS) not meeting GA needs

5 Approach to survey Survey Methodology Airspace Infringement model; Focus groups; Web-based questionnaire. Analysis Methods Qualitative method; Quantitative method.

8 Actual infringements Have HAVE you YOU ever EVER made MADE AN an AIRSPACE Airspace INFRINGEMENT? infringement? No 46.51% Yes 53.49% Yes 53.49%

9 Actual infringements HAVE YOU EVER MADE AN AIRSPACE INFRINGEMENT? What was the nature of flight? 100.0% Training flight 90.0% 80.0% 77.1% Private flight 70.0% 60.0% 50.0% Business / Passenger flight Ferry Flight 40.0% 30.0% Research / Surveillance / Inspection 20.0% 10.0% 11.9% 5.9% 1.6% 1.2% 2.4% Other 0.0%

10 Actual infringements HAVE YOU EVER MADE AN AIRSPACE INFRINGEMENT? What method of navigation did you use? 57.3% 60.0% Visual 50.0% Conventional navaids (VOR/DME/NDB) 40.0% 30.0% 19.0% GPS 20.0% 13.8% 9.9% Moving map 10.0% 0.0%

11 Actual infringements HAVE YOU EVER MADE AN AIRSPACE INFRINGEMENT? Only very limited Did this lead number to a conflict (close encounter) of infringements with another aircraft? (4.7%) involve close encounter with another aircraft. This finding is fully consistent with the results of the statistical analysis of airspace infringement occurrence No reports provided by European states to 95.26% Eurocontrol. According to Eurocontrol Safety Regulation Commission the share of airspace infringement incidents of serious and major severity 95.26% Yes is as high as 4.5% in 2006 [EUROCONTROL SRC Yes 4.74% Annual safety report 2006]. 4.74%

12 Main causal factors - Interviews N Causal factor Inadequate training and navigation skills Honest mistake High workload (overload) NOTAMs difficult to understand Airspace structure difficult to identify in flight

13 Suggested prevention Interviews Standardisation and simplification of maps and charts in Europe Improve NOTAM readability, implement integrated aeronautical briefing facility Review airspace design, reduce complexity and better use of it Extend scope and harmonise FIS provision (incl. controllers training) to handle VFR flights Improve communication between ATC and pilots Improve navigation and R/T skill training, perform periodic refresher courses and checks for pilots Use of modern technology

14 Main causal factors - Questionnaire Communication or navigation failure Provided ATS/FIS not meeting VFR flights needs Bad weather Insufficient pre-flight preparation or insufficient training Pilot unaware of or unfamiliar with airspace Distraction or high pilot workload Complex, unclear message or use of non standard R/T by ATS/FIS

15 Suggested prevention - Questionnaire Improved pilot-controller communication Improved services to VFR flights (ATS, FIS, AIS) Improved pilot s training and pre-flight preparation Introducing refresher courses and theoretical training Use of better/advanced equipment (GPS, ADS-B, Moving map) Improved pilot s vigilance on flight execution Improved airspace design and standardised VFR charts and maps Better use of navigation and communications equipment Better use of ATS/FIS services

16 See & Avoid Concept - Questionnaire DO YOU THINK THAT SEE AND AVOID CONCEPT CAN ENSURE THE SAFETY OF VFR FLIGHTS IN Do you think that See and Avoid concept can ensure the safety of VFR THE FUTURE? flights in the future? Yes Yes 63.21% 63.21% No 36.79% No 36.79%

17 See & Avoid Concept - Questionnaire What can be done to improve safety of VFR flights? 30.0% 28.8% 26.4% Better AIS 25.0% 21.6% Pilot proficiency Better/advanced equipment 20.0% 15.4% Better ATS tailored to GA needs 15.0% Review rules and regulations 10.0% 4.7% 7.6% Reduce complexity of airspace & procedure 5.0% 3.6% Other 0.0%
