Now we come to part where you can customize a few parameters so suit your
personal requirements. To change a parameter, follow the instructions as
explained in the setup paragraph earlier.
- STALL WARNING (parameter 6 stal): this is the speed at which the stall warning
will activate. To change this value, go to parameter 6 stal and press
or
. We suggest
you choose a value slightly more than the real stall value to avoid getting too close
to a stall.
- ACOUSTIC VARIO CUT-IN (param. 1,2 v-up/dw):
This is the classic vario function. This is the level at which the acoustic tone will cut
in when you reach the specified rate of lift or sink. To change this value, go to the 1
v-UP parameter, (lift rate setting in m/s), Press
and when the value starts to flash,
press
or
to increase or decrease the value. Press
again to quit.
to setup the sink rate value and repeat the instructions as for the the lift
rate. We suggest that you set this value quite high to avoid having it cut in too often.
The lift rate setting should be set up before each fight based on the estimated
conditions at the time.
-VARIO FREQUENCY MODULATION (parameter 3 soun): The vario has a
variable acoustic tone, that is to say, the intensity varies with the rate of lift. You
can set this frequency to reflect the conditions in flight. In fact, inweak conditions
there's not much point in setting it to indicate lift from +1 to +10, it's more
important to know the difference between a +1 and a +2. You can set this up
before takeoff, (0=classic setting, 1=weak conditions, 2=medium conditions,
3=strong conditions).
To change this setting, go to the 3 soun parameter and press
or
to select 1 2 o 3 according to the
estimated conditions.
- VARIO SENSITIVITY (parameter 4 svar): this parameter changes to way the vario
reacts. In fact, if we set this too low, it will react to any slight change of lift. On the
other hand, if we set it too high, it won’t react to small changes which we need to
know about. To change this setting, go to the 4 svar parameter and press
or
To change this setting, go to the 15 mcr parameter and press
o
to memorize the value.
- AVERAGE CALCULATION OF MCCREADY EQUIVALENT AND STF (parameter
16 mcre): this is a calculated average of the McCready equivalent and STF. This is
used to determine how the McCready value should be averaged in the formula
that will then give us the McCready equivalent and therefore the speed to fly, a
function that is important in strong conditions because if we don’t make it more
inert, we will have continual correction indications. On the other hand, in weak
conditions, we need to set it to be more reactive. This function will not activate if the
value is 0, valid values go from 1 to 10 and indicate the number of averages used
for the calculation (1 is reactive and 10 is inert). The equivalent McCready value
indicates the McCready value using the actual relative wind speed as optimal
(speed to fly). To change this setting, go to the 16 mcre parameter and press
, the value
will start to flash, (shown in m/s), to change the value, press

you can change the value
from 1 to 10 where 1 is the highest sensitivity setting. The base setting is 1 because
the Graviter comes with an Intellivario function which filters out interferences, so
we suggest you leave it on 1, and let the Intellivario intervene automatically. Only if
conditions are particularly strong we suggest you change this setting.
- MCCREADY VALUE (parameter 15 mcr): this is a function we’ll go into more
detail later. In just a few words, this is the average climb rate expected in the next
thermal.
