If this parameter (ADVANCED SETUP \ n. 5 POLA) is set to “OFF”, all information relating
to McCready, McCready Equivalent, Thermal Sniffer, Netto Vario is not displayed on the
instrument, creating a cleaner display for users not needing this functionality.
There are three polars preloaded, (2 for hang gliders and 1 for a paraglider). To see the
three default polar curves and to calculate your own, use the Digifly Excel software
available from the Digifly web site (www.digifly.com).
We suggest that you insert your own polar curve data which best reflects the actual
performance of your glider.

SPEED TO FLY
To utilize the speed to fly functions you must have an air speed probe connected. The
optional air speed probe should be plugged in to the right hand socket on the bottom of
the vario.
If this parameter (ADVANCED SETUP \ n. 5 POLA) is set to “OFF”, all information relating
to McCready, McCready Equivalent, Thermal Sniffer, Netto Vario is not displayed on the
instrument, creating a cleaner display for users not needing this functionality.
The speed to fly value is the optimum flying speed to obtain the best glide ratio. This
value depends on performance of your glider as well as vertical and horizontal airflow. In
calm air, the optimum flying speed is the same as the best glide speed (point B on the
figure).
On the figure above, you can see different values of speed to fly value related to different
flight conditions.
