2.1.4 Vario settings
Settings of this menu defines vario characteristics
and some other important inputs connected to
vario and speed command.
Vario:
-
vario filter
defines dynamic of vario needle
lover number means faster reaction and vice versa
-
smart vario
*
-
vario average
time (display on vario unit)
-
vario scale
, three options (2.5, 5 and 10 m/s)
(5, 10 and 20 kts, if defined in Units)
Other:
-
Silence range
, defines no audio area around zero
by speed command,
-
SC switching threshold
, changeover speed
which will change from Vario to SC in case of
Auto setting
-
ETA
(Estimate Time of Arrival) calculation, you can
choose between several options
-
Automatic SC switching

change over to SC

switch status which change over to SC
TE value
***, set TE compensation style, 0%
for tube compensation
TE filter***
only valid by electronic TE compensation

The LX system incorporates two configurable electronic filters in the circuitry. The first filter adjusts the
time constant and is adjustable between 0.5 and 5 seconds. The 0.5 setting is the fastest while the 5
setting provides maximum damping.
The second filter, called the Smart Vario, is a dynamic filter and controls the rate at which the vario
indication moves. When set to OFF, there is no restriction on the rate of movement of the vario indication
other than the setting of the time constant filter. When set to 1, the vario indication will not move faster
than 1 m/s (2 kts) per second, while when set to 4, the vario indication will not move faster than 4 m/s
(8kts) per second. It should be noted that when set to 4, the vario indication will move four times faster
than when set to 1.
Summary:
The Smart Vario should not be used in isolation but in conjunction with the setting of the time constant
filter. When the Smart Vario is activated, the time constant filter may need further adjustment to
provide optimum indications.
