All glider data will be copied from the chosen polar. The check the best glide ratio and
minimum sink rate, to see if the polar data matches the glider performance, you may look in
MacCready setting menu. You can modify the polar by changing coefficients a , b and c . A
polar is defined as a quadratic equation with the parameters a, b, and c. Use the SeeYou
program (Tools->Polar) to calculate coefficients a, b and c for a given glider’s polar. The
program requires three sink points entered at selected speeds (e.g.: 100 km/h, 130 km/h,
and 150 km/h). The program will calculate the values of a, b and c, which should be noted
and entered into the LXNAV V7.
Stall speed is used to generate stall warnings which are available only with integrated Voice
module (Not integrated in LXNAV V7).
Weights must be entered and user should enter ballast in kilograms. There are three
weights to enter. Min. weight corresponds to the min.load value and represents the value
at which the polar was measured or recalculated. Max. weight is the maximum take-off
weight allowed for a glider. It is not used in the calculation, it is just a reminder to the pilot
of the maximum take-off weight.
Empty weight is weight of the glider without pilot and
ballast. The overload factor is calculated as:
weight glider Minimum
ballast Water weight Pilot weight glider Empty

Pilot weight is weight of the pilot with parachute and baggage.
5.3.9 Flarm
By enabling the item, show flarm warning Flarm warnings will be shown on the main
screen.
Each warning can be dismissed with push button. Dismiss time is time period during which
the instrument will not give you any warning after pressing dismiss. In the event that
dismiss while circling is enabled, the dismiss period will be extended until end of circling
flight is detected.
5.3.10 Password
There are several passwords which run specific procedures as listed below:
 00666 Resets all settings to factory default
 99999 will clean logbook
