Appendix B

Automated Operation

Automated operation consists of optional custom software/firmware sold 
separately and available for purchase for specific aircraft types. Automated 
operation is non-standard software containing automated tests which will 

automatically configure the FlightHawk-AV and test specific communications 
and navigation systems.

Modes of Operation

The FlightHawk-AV is available with two modes of operation:

Automatic Mode — 

Automatic Mode consists of predefined tests, tailored to 

the specific systems available on a given aircraft. These tests are designed to be 
used in conjunction with troubleshooting procedures in the aircraft’s technical 
manual to allow the technician to quickly isolate malfunctions. See 

"Automatic 

Mode" on page B-2

 for a more detailed description.

Note:

Advanced Mode is the primary mode of operation if optional 

Automatic Mode is not installed or no predefined tests available.

Advanced Mode — 

Advanced Mode is available when there are no 

predefined tests available, or when the technician is experienced in the use of 
RF test equipment. See 

"Advanced Mode" on page B-9

 for a more detailed 

description.
