ACOUSTIC VARIO PRE-THERMAL ADVIDSE
If activated, an acoustic signal with a tone and modulation significantly different of the acoustic vario,
indicates that the instantaneous sink rate is better of the glider’s minimum sink rate, therefore indicating an
area of slightly climbing air. To set the pre-thermal sound’s start threshold go to: (VARIOMETER SETUP \ n. 2
V.PT) value from 0,00 to 1,00 m/s. Suggested value 0,4 m/s.
5.2.8
VARIO SIMULATOR
For a perfect tuning of the acoustic vario without flying, it is possible to set the ‘vario simulator’ mode, setting
“ON” the parameter (VARIOMETER SETUP \ n. 18 SIMV). Then exit from menu and use the arrow keys
to set the preferred vario sound.
To deactivate the simulator set to “OFF” the parameter “SIMV”. Anyway, for safety reasons the simulator is
automatically deactivated when the instrument power on.
5.3
AIR SPEED (ANEMOMETER WITH OPTIONAL PITOT TUBE)
This sensor measures the glider’s air speed (Indicated Air Speed) that can be visualized in km/h or mph. To
change this parameter use the menu (MAIN SETUP \ n. 16 U-SP).
This function is available only installing the Pitot tube sensor module (optional). The tube will have to be
inserted in the specific housing hole located on the instrument’s top, and the parameter (ADVANCED SETUP \
n. 1 PITO) have to be set to “ON”.
The minimum speed indication is 18 km/h.
5.4
ANEMOMETER SETTING (WITH OPTIONAL PITOT TUBE)
It is possible to perform a fine tuning of the anemometer using the parameter (ADVANCED SETUP \ n. 3 KIAS)
it indicates the anemometer’s correction value (100%=no correction, 110%=increase, 90%=decrease).
Warning
: a wrong use of this parameter makes less reliable the anemometer’s indications, the calibration of
the anemometer with the Pitot tube should have done at the sea level in standard atmosphere conditions.

TIME & CHRONOGRAPH
The Digifly AIR can visualize the expected hour and time referred to a route’s waypoint, or a goal arrival.
Relative time (hour/min or min/sec with blinking points)
-
ero: relative time – expected arrival time to the start pylon cylinder shown in seconds. Negative value if it’s
too early (wrong), positive value if it’s late (right).
-
es: countdown to the start time gate
-
e1: expected arrival time to the current Waypoint
-
eA: expected arrival time to the goal (accordingly to the route)
-
