When an approaching aircraft is det

When an approaching aircraft is detected by the laser scanner, the system goes into aircraft ID mode (OPTIONAL) to check the type of aircraft that is coming in. If the incoming aircraft type differs from what the system is expecting, the GIS206-2 unit will immediately display the message “ID FAIL” on the first line, and the message “STOP”, in red, on the second line of display. The GIS206 will also send any necessary commands to the operator panel to alert the operator.
