• high reliability
• time-saving.
Real-time on-board to ground curves transmission
Economy
This unit has been developed to improve the dialogue
between airport maintenance and fl ight inspectors
and to reduce the fl ight inspection time.
Dialogue
The transmission of all acquired parameters and aircraft
position status will enable the maintenance to
monitor in real-time the effects of beacon adjustment
and measurements performed by the FIS.
