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
E
stimated
T
ime of
A
rrival. 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 (
E
stimate
T
ime of
A
rrival,
E
stimate
T
ime
E
lapsed) 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.
