Experience with RNAVAn example how to get it
implemented

• Capt. Helmut HahnManager RNAV Procedures
• Capt. A-320
• Eurowings FlugFlight Operations

2
The way into full RNAV

• Eurowings was first airline in Europe to
  conductGPS - (Overlay) Approaches since
  1994---gt ATR-72
• Joint project group formed in march 1994 out
  ofAuthority LBA (German CAA)ATC DFSOperator
  EurowingsIndustry Honeywell

The way into full RNAV

• The inputs in detailLBA special certification
  for A/C and crewsDFS special design of
  GPS-NPA conversion of data into
  WGS-84 radartracking of approaches for
  analysisHoneywell provision of hardware,
  software supportEurowings Flight operations
  incl. Retrofit special crew training (24 crews)
  checks

4
The way into full RNAV

• January 1995 start of GPS - TrialAirports
  Frankfurt, Nuremberg, Munich, Berlin
• Intermediate evaluation---gt technical problems
  in regard of FMS - Hardware database problems,
  e.g. location of waypoints
• July 1995 end of trial period---gt final
  evaluation

5
The (GPS) - Evaluation

• Accuracy Lateral deviation from track lt 100 m
• Availability 100 ---gt no degradings, no RAIM
  alarms
• Feedback Pilots no operational
  problems ATC no operational problems
• Benefits Coupled GPS - NPAs possible reduced
  flightcrew workload reduced human factor
  induced errors

6
The Implementation

• All German conventional procedures where
  redesigned and published as GPS - Overlay
  approaches---gt Migration to stand alone
  GPS-Approaches in 10/98 Trial Lufthansa,
  Eurowings, Condor ----gt first unrestricted Ops
  Approval in 06/98 for Lufthansa A-320fam
  fleet
• Since 10/00 GPS - SID trial at 3 German
  airports---gt Münster, Paderborn, Dortmund

Conclusions - Goals

• Redesign of applicable procedures in the view of
  updated RNAV - Knowledge---gt ammended ICAO PANS
  OPS
• Optimized procedures in terms of mileage, flow
  optimization, safety, environmental benefits,
  human factor issues
• State authorities have to catch up in terms of
  timely and usable regulations and procedures

---gt this is the only way to CASH IN the
possible benefits
