6.1 Equipment Description
NOTE
There is no TSO/ETSO applicable to the GDU 4XX.
NOTE
GPS data is used for ADAHRS sensor drift correction, so at least one source of GPS data
is required. This requirement can be met by installing a GPS 20A, or by connecting a GPS
antenna to at least one GDU GPS receiver. In a system with multiple GDU displays,
additional GPS antennas may be connected to the other displays for redundancy, if
desired.
NOTE
Make sure that no dust or grit accumulates at the bottom of the display glass. The
GDU 4XX displays us invisible infrared beams for touch detection, this makes it very
important to keep the screen clean, especially along the edges.
NOTE
See Section 32.2.1.5 for information on replacing a GDU 37X display with a GDU 4XX
display.
