• ROUTE - route flown will be shown
On pressing ENTER with the cursor on ROUTE, the display shows:
To program ZOOM, press ENTER and a small cross will appear in the middle of the screen. Move the cross by
rotating ZOOM and the UP/DOWN selector. Press ENTER when the cross is positioned at the start of the area to be
zoomed. Repeat the procedure for a second cross and place at the end of the area to be zoomed. Press ENTER and the
expanded area will be displayed.
• BAROGRAM - barogram of the flight
The zoom procedure is similar, but there is no cross. After pressing ENTER, a vertical bar will appear which can be
moved (with UP/DOWN) and fixed with ENTER again. The same procedure is used to place the second bar.
2.3 Variometer and Altimeter
All signals from the pneumatic sensors (altitude, speed) are derived from high quality pressure sensors which means that
no flask is necessary. The vario signal is derived from the altitude signal. All signals are temperature compensated
while the vario and speed signals are altitude compensated as well. A custom programmable LCD has been designed to
display the vario information as well as many other parameters. The display is user configurable.
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
• netto vario air mass lift and sink
• relative vario shows the lift or sink that would be achieved if the glider was circled at thermalling speed
There are two ways by which the vario indications can be corrected for total energy; electronic TE compensation based
on speed changes with time; and pneumatic compensation with a TE tube. When using pneumatic compensation from a
TE tube, the LX 7007 PRO IGC does not process the signal in any way. 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 port should be connected to a good static pressure source. If
pneumatic compensation is selected, then the TE port should be connected to the TE tube.
