HSI 360° MODE
SELECTION
The EFS 40/50 EHSI has four
possible 360-degree display for-
mats: standard HSI compass
rose, NAV map, NAV map with
weather, and DG mode. Each
press of the HSI button sequen-
tially selects the next display for-
mat. A press of the HSI button
while in the AR C mode will
change the display to the stan-
dard HSI compass rose.
The display selection list may
include the following:
2.1.5 Issued 8/10 SW 04/05/06/07/08/09/10/11/12/13/14/15/16
DG and WEATHER are options
selected at the time of installation
and are included in the system
certification. Software 06 added
lightning detection presentation.
If a compatible weather radar or
lightning detection is not
installed, the weather option will
not be in the sequence.
Software release 05 added a
Heading Bug to the DG mode.
Primary use of this display format
is for training or as an option to
provide an uncluttered display for
an NDB approach (using the
EHSI as an ADF RMI).
Software release 07 provides the
additional, optional display format
of "Plan View" which can be con-
figured for display on the MFD
