3.5 Using GPS/VHF Systems with the EXP5000

You can use the EXP5000 to set a primary navigation course setting

on the HSI when one of three conditions is met:

● PFD Nav Source = GPS 1 or GPS 2 and the selected GPS/VHF

system is in OBS mode.

● PFD Nav Source = VLOC 1 or VLOC 2 and the current

frequency is a VOR station.

● PFD Nav Source = VLOC 1 or VLOC 2 and the current

frequency is an ILS or localizer. In this case, you can set a

course for reference. The CDI is driven by the received localizer

signal, regardless of the course set.

The CDI scale on the EXP5000’s HSI is automatically set by the

GPS/VHF system as a function of the Nav source you select with the

PFD Nav button.

Figure 9. Setting CDI Scale on EXP5000’s HSI

The source you select for Nav is coupled with the CDI button on the

GPS/VHF unit, as follows:

● When you toggle the Nav button on the EXP5000 from GPS 1 to

VLOC 1 and back, the CDI source on GPS 1 changes from GPS

to VLOC and back to match the current Nav setting.

● Similarly, when you toggle the CDI button on the GPS/VHF unit

from GPS to VLOC and back, the Nav source on the EXP5000

changes to match.

➥ Avidyne recommends that you use the CDI button on GPS 1 to

toggle the Nav source back and forth, especially for dual-GPS

installations where the PFD Nav button cycles through all four

Nav sources (GPS 1, VLOC 1, GPS 2, VLOC 2), and the CDI

button on GPS 1 makes it easy to switch the EXP5000

between GPS 1 and VLOC 1 and back.
