Variometer

 and altimeter 

All signals from the pneumatic sensors (altitude, speed) are derived from high quality digital pressure sensors 
which  mean  that  no  flask  is  necessary.  The  vario  signal  is  derived  from  the  altitude  signal.  All  signals  are 
temperature and altitude compensated.  The variometer can be configured to show:  
 

•

 

range           

               5,10 and 2.5 m/s   10,20 and 5 kts 

•

 

five time constants   

  1s to 5s, in addition there are 4 settings of electronic processing for the vario 

                                                     signal acquisition    

•

 

netto vario                             air mass lift and sink 

•

 

relative vario  

               shows the lift or sink that would be achieved if the glider was circled at 

                                                     thermaling speed     
 
There  are  two  ways  by  which  the  vario  units  can  be  corrected  for  total  energy;  electronic  TE  compensation 
based  on  speed  changes  with  time;  and  pneumatic  compensation  with  a  TE  probe.  When  using  pneumatic 
compensation by use of a TE probe. The quality of the TE compensation depends entirely on the location, size 
and dimension of the TE tube. The installation must be leak-proof. 
 

Note! 

If electronic TE compensation is selected, then the TE(Pst) port should be connected to a good static pressure 

source. If pneumatic compensation is selected, then the TE(Pst)  port should be connected to the TE probe.

2.5.1 

Smart Vario description 

 
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.
