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.
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.
