OPERATION CHECKLIST BEFORE A TASK
Be certain that the batteries are fully charged
Download the waypoints from the competition organization web site
Upload them on the Digifly Air with the software AirTools (PC) or GpsDump (PC e MAC), or copy them
transferring the file from one instrument to the other using the direct connection cable.
Edit a route accordingly to the task’s director instruction
Insert correctly the turn points cylinders radius
Insert correctly the start info (entering or leaving)
Insert correctly the start hour
If existing, insert also the ulterior gate time ( how may and when)
In the route page verify that the total distance is corresponding (“Tot dst km”)
Activate the route
Set the barometric altimeter, it is top important because it used also by the glide’s computer.
Before the takeoff, provide to turn on the instrument with the proper advance to acquire the proper GPS
position
After the GPS point acquisition, verify that the time is correct, in case correct the time zone (pay attention to
the summer time shift) otherwise the start time will be totally wrong.

NAVIGATION ROUTE
To have these info available it has to be activated a route’s navigation.
12.1
DIRECTION, DISTANCE & HEIGHT ON THE WAYPOINTS
This function indicates the direction, distance and the estimated arrival height above the current waypoint
(H1); the next Waypoint (H2) and the goal’s Waypoint (HA).
The arrival height above the current Waypoint (H1) is computed accordingly of the following info: Altimeter A1,
distance to Waypoint, Waypoint’s altitude and medium glide ratio.
The medium Glide Ratio is constantly updated during the glide and memorized during the thermal flight, to
change the GR media calculation time (in seconds) go to (ADVANCED SETUP \ n. 5 EFFA).
12.2
NEEDED GLIDE RATIO TO CURRENT WAYPOINT / NEXT WAYPOINT / GOAL
It is the estimated needed glide ratio to reach the current waypoint.
This info is available in all the three screens (Thermal, Glide Compass, and Glide Plotter) using the tools
“efr1”, “efr2”, “efrA”.
