Note: See also section 2.14 for an alternate means of changing the navi-
gation source.
2.8 DISPLAY MODE (MODE)
The display mode menu item allows the selection of the current display
mode. Menu options include:
• HSI mode - Displays standard HSI information in a 360-degree view
about the aircraft and acts as a standard HSI display. If the display
mode is changed to HSI Mode while the lightning overlay is shown,
the unit will annunciate NO TRFC/LGHTN.
• 360 Map mode - Displays navigational information in a 360-degree
view about the aircraft, including GPS map information for direct-to
and active flight plan waypoints. The lightning overlay may also be
displayed in this mode.
• Arc Map mode - Displays an exploded view of the 360 Map mode,
but only 45 degrees either side of the aircraft heading is visible. The
lightning overlay may also be displayed while in this mode.
2.9 BEARING POINTER SOURCE (BRG)
The Bearing Pointer Source menu item allows the selection of the bearing
pointer source.
2.10 LIGHTNING OVERLAY (LGHTN)
The lightning overlay is available only if the EHSI is configured with a
Goodrich WX-500 Stormscope®. The lightning menu allows the selection
of the lightning overlay.
If the LGHTN menu item is selected while in HSI mode, the option on the
right is initially blank. If the lightning option is changed to CELL or STRK
mode, the EHSI will automatically change the display mode to 360 Map
mode and will annunciate MODE CHANGED. If the range is less then 10
NM and lightning mode is in cell or strike, NO LIGHTNING is annunciated.
This annunciation takes precedence over the MODE CHANGED annunci-
ation.
The lightning overlay menu item contains three options:
• Cell mode - The EHSI displays clusters of electrical activity indicat-
ing storm cell areas.
• Strike mode - The EHSI displays individual electrical discharges.
