Time Based Separation Project

• Initial Arrival Capacity Recovery Estimate
• Up to four arrival slots can be recovered per
  hour
• Initial Hazard Analysis
• No indications that the procedure will be unsafe
• Initial reaction from ICAO
• No initial objections, follow-up required
• Acceptance from ATC Controllers
• Controllers that have been exposed to the concept
  are aware of the problem and supportive
• Acceptance by airline pilots
• No negative reactions from pilots

Time Based Separation Project

• The initial feasibility study will be completed
  this year.
• The EUROCONTROL Airport Domain will propose that
  the project enters into the programme initiation
  phase
• Further validation will then be undertaken

Cross Wind Departures
7
The way forward for Cross Wind

• Study the transportation of Wake Vortex in Cross
  wind conditions
• Study the In-ground effect
• Develop the Cross Wind Departure Operational
  concept
• Look into Cross wind arrivals
• The activity is undertaken in cooperation with
  the FAA
