Level Bust & ACAS in general 2008 - 2013 • • • • • • Analysis and statistic based on the 12.000 pilots’ and ANSPs reports 5.4% of the EVAIR occurrences were identified as LBs 12.6% of the EVAIR occurrences were identified as ACAS RAs 11% of LB were followed by ACAS 57 airlines participating in LB 87 airlines participating in ACAS RA 05/01/2020 2

  7. Severe turbulence encountered crossing from mountainous region (near turbo reporting point). Aircraft unable to maintain speed and altitude, 450ft approx altitude loss before able to sustain clearance from FL360 to FL340. • 05/01/2020 8

  8. Drilling through contributing factors Aircraft was cleared by ATC to descent 5000' and to turn left heading 150. Clearance read back by f/o, confirmed by captain. While at 5000' ATC told us to climb back to 6000' since that was the clearance. Aircraft climbed back to 6000'. Approach and landing uneventful. Capt and f/o were both convinced that the clearance was 5000' since it was read back to ATC. VMC with terrain at all times. Feedback – ATC clearance was 6000’ – Hear back omitted • 05/01/2020 9

  9. Drilling through contributing factors cont. In average 10% of the LBs have planning as one of the contributing factors 05/01/2020 10

  10. Short summary of EVAIR LB & ACAS findings A/G communication with the Hear back omitted, Misunderstanding and Call sign confusion is a dominating as a contributing factor High vertical rate with the lack of traffic information Mistakes with the planning and the new/old role of the planning ATCO within the strip less environment Timely information about MET conditions Impact of the super heavy A/C • • • • • 05/01/2020 11
