HSI Page
The ‘Big Numbers’ option (selected using the
MENU
key)
shows two large character data fields. Like the small
character fields, the desired data is user-selectable.
A split screen, showing the HSI and a smaller area map, is
also available using the
MENU
key.
If the HSI Page is not currently displayed, press PAGE (repeatedly) until the HSI Page
appears.
The HSI (horizontal situation indicator) Page provides graphic steering guidance to a destination
waypoint and, along with the Map Page, will become one of your primary navigation screens. The HSI
Page graphically depicts a mechanical HSI, showing the desired course as a “course deviation needle”
and a “desired course pointer”. If you move off course the needle will indicate off course distance and
direction. To return to the desired course, simply steer toward the needle until it returns to the center of
the HSI. The course deviation scale limits are adjustable, with the current scale indicated at the bottom
of the page. The scale setting represents the distance from the center of the HSI to full left or right
limits.
The HSI depicts your track (also referred to as “ground track”) heading using a rotating “compass
card”. Don’t confuse this figure with the aircraft heading indicated on your panel instruments. On a
windy day these two figures can differ significantly!
The HSI Page also provides a TO/FROM indication at the center of the graphic HSI, along with
vertical guidance when using the unit’s vertical navigation (VNAV) features. User-selectable data fields
appear along the right-hand side of the page and may include a ‘Big Numbers’ format or a map display.
