EVA Summary
Procedure Mix EVA ? Classic Visual Following

• Facts
• Only 1 misinterpretations happened during the
  simulation sessions (4 out of 275 landings)
• 3 cases Controller instructed the classical
  Visual Following procedure although the aircraft
  was able to perform the EVA procedure
• 1 case Controller instructed the aircraft to
  perform the EVA procedure although the aircraft
  was not equipped
• controller misinterpretations happened
  independent from the equipage rate (0, 30, 70)

Summary
NUP EVA simulation runs highlighted some specific
issues of the proposed phraseology to be put
into the Global Discussion on Third Party
Identification.
1. Modified Phraseology Proposal
Lufthansa 123, Maintain own visual separation to
Delta Lima Hotel 234
tested phraseology
Lufthansa 123, Maintain own visual separation
234 Lufthansa
new proposal
2. Procedure Mix between EVA (with CDTI) and
Visual Following Procedure (without CDTI) seems
to be possible.
