Operating Instructions AV Pilot II

N. B.: Incorrect manipulation of the correction value of the pressure sensor will result in false
altitude readings! Never alter the basic settings of the altimeter unless you have good reason
to do so (in your own interest)!
In option mode, the indicators OPTION and ALT 1 appear and the relevant number of the modu-
le is shown at the top of the display. The unit to be adjusted will flash.
Altimeter 2 (ALT 2)
Altimeter 2 can either be used as an absolute alti-
meter or as a relative altimeter.
When used as an absolute altimeter, it functions in
precisely the same way as altimeter 1. Altimeter 2
can now, for example, display the altitude in feet
and altimeter 1 the altitude in meters.
The relative altimeter displays the current altitude
with reference to a point. This reference point can
be set at zero in run mode at any time by using the
key or set at any altitude in setting mode. The
relative altimeter can thus be used to measure the
higher altitude of the take-off area. Pressing the
key at the take-off area will zero ALT 2 for this
purpose.
Altimeter 2 setting mode
The altitude can be set in setting mode in precise-
ly the same way as with altimeter 1.
If altimeter 2 is selected as the absolute altimeter,
it is coupled to altimeter 1. Any change in the dis-
play for altimeter 1 is reflected by a corresponding
change in the display for altimeter 2 and vice-
versa.
Altimeter 2 option mode
In option mode, you can select the unit (meters or feet) at the first level as with altimeter 1. The
unit selected flashes in the display. You can toggle between units by pressing either the key
or the key.
Press key to enter the second level of option mode. At this level, you select the operating
mode of altimeter 2. If this is set at absolute altimete, the two indicators ALT 1 and ALT 2 will
flash in the display. If set at relative altimeter, only the indicator ALT 2 will flash.
You return from option mode to run mode by waiting 15 seconds or again pressing the two
keys marked “OPTION” simultaneously.
