3 – Drift Correction (NO GPS mode)
Pressing this switch momentarily right or left allows the pilot to adjust roll TRIM either
right or left by one trim count. This is a very fine trim adjustment. If the switch is held for
longer than 1 second in either the right or left position the trim bias count is shifted right
or left at a significantly faster rate until the switch is released. The upper right field in the
display will provide a graphic display of the trim position while the switch is activated and
for about two seconds after the switch is released. If the GPS data to the EZ Pilot is
unavailable, as indicated by a NO GPS warning, the L-R switch provides a method to
turn the airplane to a new heading or stabilize the aircraft in a straight and level attitude.
4 – Changing various parameters
The L-R switch is used in conjunction with the MODE and DISPLAY switches in the
setup and calibration modes to change the various settings. These will be described in
the setup procedures (Section 9) of the manual.
3.2 Display Information
Pilot information for navigation is provided on a high
contrast, bright vacuum fluorescent display (VFD), or
an optional transflective LCD (backlighted). 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.
The display example shows the normal power up default display with GPS data present.
3.2.1 Power up Display
W
hen the EZ 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) If GPS signals are present on the EZ 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.
3.2.2 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).
Optionally, the purchaser may program their
own 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 setup menu screens (section 9).
3.2.3 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 five seconds. In
all cases the navigation display will return to
normal automatically when the GPS signals are reacquired. Note that there may be a
delay of up to seven seconds in restoring the display after a GPS signal becomes active on
