Information Fields
Horizontal Navigation (H NAV)
Pilot information for navigation is provided on a high contrast, bright Polymer LED (OLED), or an optional
transflective LCD screen. Several fields on this display are multiplexed (i.e. they use the same display
space to present different information). This allows the pilot to view all navigation parameters including
digital rate of turn information. This section will explain in detail the horizontal navigational features and
display screens available.
Power up Display
When the Pro Pilot is powered on a logo display is present showing the firmware revision operating in the
unit. (This can be field programmed to present a personalized screen at power on).
Initial Logo Screen
The initial factory logo screen shows the product information
including the firmware revision level and unit serial number in
the extreme right part of the display (represented by the X’s).
The purchaser may program a personalized logo screen.
Each time the unit is turned on it will display this information.
This information can be field re-programmed at any time by
entering the CONFIGURATION menu screens (Chapter 7).
BARO SET Screen
When the Logo screen expires after a few seconds, the BARO
SET screen will be seen.
No functions will be available until the altitude value is set and the encoder is pressed. The value should
be set to agree with the primary aircraft altimeter, which has been corrected for current reported
barometric pressure. The value may be changed in either five foot (ELEVATION) while on the ground or
twenty foot (ALTITUDE) increments while in flight.
If GPS signals are present on the Pro Pilot interface the display will switch automatically to the navigation
display. If no GPS signals are present the screen will change to show that NO GPS is being received on
the interface.
NO GPS Screen
The “NO GPS” screen will display on power up if no GPS signal
is present or if the GPS signal is lost for a period exceeding
seven seconds.
In all cases the navigation display will return to normal automatically when the GPS signals are reacquired.
Note: There may be a delay of up to seven seconds in restoring the display after a GPS signal becomes
active on the interface.
In the event the GPS signal is lost during normal area navigation, the "NO GPS" screen will be shown and
the Pro Pilot will automatically go into the wing leveler mode and follow a “straight and level” course. In
this mode, manual corrections to the dead reckoning track can be made using encoder knob.
