5.3.3 QNH and RES
Turn the knob to select the required entry field. Press the PUSH button and start editing
the value.
5.3.3.1 QNH
This feature may be used to offset the altitude datum as the result of pressure changes
during the flight. Since changing the QNH influences the indicated altitude, care should be
taken when changing the value as an incorrect setting could upset the final glide calculation.
5.3.3.2 Safety Altitude
This setting is the altitude reserve or safety altitude and is the height that the instrument
adds to the final glide altitude required so the glider arrives over the final glide destination at
the selected safety altitude. Once the safety altitude has been specified, the pilot has to
keep the final glide indicator on 0 to arrive at the safety altitude.
5.3.3.3 Set elevation
If Set Elevation – show on start-up, item is not checked, Set elevation menu, will not be displayed
during start up. In this case elevation will be set to standard QNE (Flight level).
