10. Advanced settings
OFF - Turns the GPS LS OFF
ALTI 1 - Altimeter 1
ALTI 2 - Altimeter 2 - Get your ALT1 from GPS: Press Menu - Use UP
and DOWN until AL1-GPS is visible. Press enter do edit the required
setting. You can set it to YES, NO, or AUTO. Use UP or DOWN to change
the setting. Press ENTER to accept the value. Press MENU to exit to main
menu or to the flight page.
QNH - Setting the altimeter (ALT 1 and ALT2), allows the user to adjusts
the barometric altimeter. A barometric altimeter calculates altitude based
on atmospheric pressure , and should not be confused with the GPS
altitude,
Since atmospheric pressure can vary substantially with meteorological
conditions, and so with time, the barometric altitude also varies according.
In order to have the correct altitude for a certain place the altimeter should
be calibrated.
Calibrating the altimeter can be achieved by entering the know altitude of
the location. Entering an altitude automatically calculates the QNH, which
is the local barometric pressure adjusted to sea level.
Alternatively, the altimeter can be calibrated by adjusting the QNH for the
local, and time. Changing the QNH will adjust the barometric altitude.
CLTH - The Climb Threshold defines the rate of climb at which the vario
will start beeping. The frequency of the first beep is defined through the
Base Frequency parameter,and steadily increases according the
Increments parameter value.
The default value for Climb Threshold is 0.1m/s. This means that beeping
starts once the instantaneous vario value goes above 0.1m/s.
SKTH - The Sink Threshold is the rate of descent at which the vario will
emit a low frequency sound. Contrary to the climb sound the sink sound is
continuous. The deeper the sink rate the lower the sound frequency.
Default value for this parameter is -2 m/s, we suggest setting a value lower
than the natural sink rate of the glider when flying on speed bar in still air.
SKAL - The Sink Alarm defines a vertical speed value at which a sound
(alarm siren) starts to be produced. For example, if the Sink Alarm is set to
-10m/s, then if the instantaneous vario goes below -10m/s, and alarm will
be fired. This alarm can be used to identify high vertical speeds, as for
example, in a spiral dive. The Sink Alarm parameter can vary from 0 to
-25m/s. Set the Sink Alarm to 0 (ZERO) to disable the alarm.
INTG - The Integrated vario is calculated by integrating the vertical speed
during a period of X seconds defined by this value.
