the displayed altitude A1 should be gauged before each take-off to the actual, true height
at location. Pressing the ▲key will increase the displayed altitude, the ▼ key will decrease
altitude. The info line will show:
Mod Alt1 ▲▼ (= modify Alt1). Due to this adjustment the air
pressure display will also change. This air pressure value (QNH) is always related to sea
level height.
If the user does not know the altitude of his present location, he may obtain the data
by fading in the „User Field QNH“ and, using the arrow keys, by changing the altitude
value until the QNH matches the actual QNH as per weather forecast.
If the GPS system receives satellites, the GPS-altitude is applied as Alt1 by pressing
the F2 key. If there is no GPS reception, it is possible to set the altitude Alt1 by use
of key F1 to a value which complies to QNH pressure of 1013 hPa. If the altitude of
any given landing place is set to 0m, after take-off there will be of course always be
displayed the altitude above this location. The related air pressure (QFE) is the real
present air pressure at this place in hPa, which differs of course from QNH according
to the difference of altitude, as QNH is the pressure at sea level.
2.1.2 Altimeter A2, relative height
A2
(in the user selectable fields) is a reference height, it can be modified by use of the
arrow keys ▲▼. Long pressure on F2/Alt2 generates the display „Mod A2 ↑↓“ in the
information line. By use of the arrow keys it is possible to set the height difference, or
to set with brief pressure on F2/SET 0 the height difference to 0.
2.1.3 Altimeter A3, cumulated height
A3
(in the user selectable fields) sums up the total height meters gained during one flight.
For thermal flights this height is dependant on flight time. If several pilots complete the same
flight task, then the one who had the least gain in height (A3) would have been the best to
accomplish the task.
Within the user selectable fields it is also possible to choose altitude A1 in ft. This
information is important when in contact with the air traffic manager in Restricted Areas.
Furthermore it is possible to choose FL (ft) in the user selectable fields. This is an
altitude display in feet for the flight level. This feature is not adjustable and is always
related to a QNH value of 1013 hPa (air pressure at sea level). This display is particularly
important for pilots of microlight aircraft to whom is assigned a Flight Level by air traffic-
controllers during flights in Restricted Areas.
A2, A3, FL
or QNH may be selected within the user selectable fields.
