Agenda Regulatory WLAN Considerations Setting The Pace FlyNet Services FlyNet Technology Regulatory WLAN Considerations Questions & Answers

Initial Position on WLAN Devices Only Lufthansa owned DO-160D qualified laptops with WLAN devices allowed All other WLAN devices are not permitted for use on board rejected by the system A general safety assessment is essential to enable passenger use of WLAN devices in aircraft

Prove the aircraft is generically immune to commercial WLAN devices How to move forward? Either specify and qualify all individual manufacturers commercial WLAN devices OR Prove the aircraft is generically immune to commercial WLAN devices

Qualify individual commercial WLAN Devices Individual qualification of passenger WLAN devices is neither reasonable nor feasible Very fast product cycles Immense cost to the operator for qualification and certification Not likely to cover each and every WLAN device in the market Impossible to enforce unqualified usage NOT AN OPTION

Prove Aircraft Immunity Analyze commercial WLAN devices Health Emissions Fault modes Operational modes Verify immunity for HIRF aircraft Establish a method and verify immunity for other aircraft

Validate Aircraft Immunity HIRF aircraft Airbus SIL for establishing EMI thresholds Processes defined in EUROCAE WG58 SAE working with EUROCAE to provide similar guidance Other aircraft Identify susceptible aircraft equipment and locations Test against worse than worst case Justifies passenger use of commercial WLAN devices in aircraft

Pending approval the vision becomes reality… Conclusion Lufthansa anticipates to be the first airline to offer its passengers access to the internet using their own WLAN devices Operational approval is expected during the trial Pending approval the vision becomes reality…
