GLS versus ILS
…from a Pilot‘s 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 Berlin‘s 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.

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.

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

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!
Malaga – Monitoring flights only!

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).
