GLS versus ILS from a Pilots view!

• Autopilot mode selection requires the same
  pilot actions for ILS and GLS approaches.
• GLS annunciations are identical to those used
  for ILS.
• Normal and Non-Normal Operations for GLS
  approaches are aligned with the Normal and
  Non-Normal Operations for an ILS approach.

GLS coupled with RNP

• Example future procedure.
• Potentially useful paths
• (avoid terrain, airspace, weather).
• RNP based.
• GLS final segment.

CAT III Certification Autoland Capability

• BOEING GLS approaches have been demonstrated
  through autoland and rollout.
• Flight Tests have shown The GLS approach is
  even more precise compared to the ILS.
• To substitute the existing ILS stations (e.g.
  in Europe) the CAT III certification is
  absolutely mandatory!

Air Berlins plans for GLS adoption

• All new Air Berlin Boeing 737 Next Generation
  aircraft will be able to conduct GLS Approaches.
  
• The Air Berlin GLS Boeing 737 Fleet
• 10 aircraft at the end of 2009
• Air Berlin will receive a total of 80 GLS
  capable aircraft in the next 5 years.
• Evaluation Approaches at Bremen and Malaga.
• Close cooperation with DFS and AENA.
• GLS introduction and development on Air Berlin
  Line operation is given a high project priority
  by Air Berlin Fleet Management.

Bremen GLS Evaluation Phase

• Air Berlin is approved by the LBA since August
  2008 to conduct GLS Evaluation approaches at
  Bremen.
• Additionally the following constraints by the
  authority must be redeemed
• GLS Setup Pilot Flying/Pilot Monitoring
• Pilot Flying (PF) will set the GLS channel.
• IMC The Pilot Monitoring (PM) will set the ILS
  frequency to crosscheck the GLS Signals (Note
  Due to Channel/Frequency mismatch the Identifier
  on the PFD may appear in amber and the FD bars on
  the PM side may disappear).
• VMC Outside visual references like PAPI or
  Runway may be used by the PM to crosscheck the
  GLS Signals.

Bremen GLS Evaluation Phase

• Minima
• The following increased Minima must be used
• Decision Altitude (DA) 440 feet
• RVR 650 Meters
• After the evaluation phase Air Berlin will
  receive the full CAT I certification for GLS
  approaches
• Decision Altitude (DA) 200 feet
• RVR 550 Meters

Malaga Monitoring flights only!

• Air Berlin is approved by the LBA since August
  2008 to conduct GLS Evaluation approaches at
  Malaga.
• Additionally the following constraints by the
  authority must be redeemed
• Pilot Monitoring (PM) will set the GLS channel.
• Due to the Ground Station prototype system design
  Air Berlin is only allowed to monitor the GLS
  Signal by the PM.
• The PF will set and fly the ILS.
• The GLS Signal in Malaga is for monitoring
  purposes only!

GLS/GBAS Statistics

• August - November 2008, 100 successful!

Why should an operator (e.g. Air Berlin) support
GLS technology?

• GLS procedures are identical to ILS procedures
  No additional training is required, which
  results in no extra costs!
• GLS coupled with RNP offers a great range of
  new approach procedures, to satisfy Emission
  requirements.
• Airport upgrading in terms of IFR approach
  procedures (e.g. La Palma, MDA 1850 ft.) more
  flexibility, less diversions.
• Lower maintenance costs for the Ground System
  results in lower Airport fees (e.g. Europe).
