2.1.1.3 INIT

The following parameters can be set using this option.


• VARIO FIL:

This sets the time constant of the vario from 0.5sec up to 5 secs; the default setting is 2.0 secs

• S.V. : S.V. means Smart Vario, giving four levels of dynamic damping of the vario indication and
off.

• VARIO INT:

This setting defines integration period for the averager in seconds; the default is 20 seconds

• VARIO RNG:

This sets the full scale range of the vario

• TAB:

This setting defines the width of the audio dead band in speed to fly mode

• ETA:

This setting selects the parameter, GS, VAR or MC, that is used to calculate the Estimated
Time of Arrival. When flying a programmed task, the calculation takes account of the
unflown portion of the task , around any TPs or APTs not yet reached

GS, bases ETA on the achieved groundspeed along track. It takes into account differences
between bearing and track of up to 90°. If the difference is greater than this, --:-- is
displayed.

VAR is based on the achieved average thermal climb rate and assumes that this is going to
continue.

MC is based on the actual Mcready setting.

Note!:

All three methods of calculating ETA and ETE (Estimate Time of Arrival, Estimate Time Elapsed) take into account
glider altitude and safety (arrival) altitude, thus ensuring that the calculation made is the best available

• AUTO SC:

This option defines the method by which the instrument is switched between vario and speed
command
OFF: Switching is by an external switch
GPS: When the GPS detects that the glider is circling
TAS: When the TAS exceeds a pre-set value. The TAS at which switching occurs can be
selected in 5 km/h steps from 100 up to 160 km/h (or the equivalent in knots or mph)

• WIND/COMPASS: N.C. means not connected. When the optional compass module is installed, the instrument

uses magnetic track to make an additional wind calculation. The calculation requires the
glider to fly straight a specified period which is set in this option. The default is 15 seconds,
but the longer the period, the more accurate is the calculated wind.

Note!:

The external switch option has absolute priority and will override all other switching methods.
