This section lists some advanced configuration and integration options. | |||

You may want to check the FG implementation of the [[Boeing 777-200]] aircraft for an extensive example of GPWS integration. This plane provides a Nasal GPWS wrapper for the mk-viii module and implements all standard (Boeing) buttons and displays, i.e.: | |||
* Self-test push button | |||
* Glide-slope warning disable button (e.g. to silence warnings during a visual approach) | |||
* Flap and gear override buttons (e.g. to silence flap/gear warnings in emergency situations, like stuck gear etc). | |||
* Terrain/GPWS disable buttons | |||
* GPWS connection to master-warning light. | |||
* GPWS connection to PFD (to display "PULL UP"). | |||
== Module I/O == | |||
* The inputs and outputs match those of the real device and are made available through the FlightGear property tree. | * The inputs and outputs match those of the real device and are made available through the FlightGear property tree. | ||
* Input monitoring is implemented. The loss of inputs required for a particular function is annunciated through the GPWS INOP and/or TERR FAIL lamps. | * Input monitoring is implemented.

The original MK VIII supports an RS232 interface to read the module status. Since FlightGear does not support RS232 interfaces, all data is printed to the standard output.
