8.1 Simulator for Ground Checks
In order to ground-check AT-1 efficiently, a comprehensive simulator function has been
implemented. The simulator is capable of simulating:
•
Several valid or invalid GPS positions, pressure altitude and ground speed of the own
aircraft.
•
Several types of traffic targets with different threat levels.
•
Traffic warnings from ‘‘normal’’ and non-bearing targets.
•
FLARM alert zone and obstacle warnings.
8.1.1 Activating the Simulator
To activate the simulator, please open the AT-1 configuration webpage as described in
section 7.1.1 and navigate to the simulator controls by clicking on Show Simulator Control .
After the AT-1 is switched off, the simulator is automatically deactivated.
8.2 Interface Checkout
8.2.1 Serial Interface Check
The serial data interface of the unit can be checked with a pragmatic function test.
1. Connect AT-1 and another compatible avionics system via a serial data port.
2. Verify correct operation.
We recommend the use of professional RS-232 analysis tools to check data bus integrity.
8.2.2 ARINC429 Interface Check
The ARINC429 data interface of the unit can be checked with a pragmatic function test.
1. Connect AT-1 and another compatible avionics system via ARINC429.
2. Verify correct operation of the interface in the compatible avionics system’s debug
console.
Please note: Without movement of the own aircraft, the AT-1 is unable to determine
the own aircraft’s current heading. Without a current heading, no traffic data is
transmitted over the ARINC429 interface and the status "STANDBY" is shown. While
