3.3 Variometer

All analogue signals of LX 7000 (altitude, speed) are derived from high quality pressure sensors, no flask is
necessary. The vario signal is derived from the altitude signal. All signals are temperature compensated. Vario and
speed signals are altitude compensated as wel. A special device based on LCD has been developed for the vario
indicator. Not only vario, but also a lot of additional information is displayed on the unit. The unit is programmable,
that means the pilot is able to preset which information is important for him.

3.3.1 Vario

•
range 5,10 and 2.5 m/s 10,20 and 5 kts
•
six time constants 0,5s to 5s
•
netto vario
•
Relative Vario
To compensate the vario there are two ways. The electronic TE compensation based on speed changes with time and
the compensation with TE tube works the mechanical way. Using tube, the LX 7000 has absolutely no influence on
compensation.
lift or sink of air mass only
lift or sink during circling (does not depend on speed)
