4 MAIN FUNCTIONS
4.1 ALTIMETERS
The Digifly AIR features 6 different altimeters: ALT 1, ALT 2, ALT 3, ALT GPS, ALT H1 e ALT HA.
- ALT 1 (A1) : Barometric altimeter.
- ALT 2 (A2) : Altimeter A2.
- ALT 3 (A3) : Last thermal height gain
- ALT GPS (AG) : Altimeter GPS.
- ALT H1 (H1) : Estimated height over the cylinder of the current WP
- ALT HA (HA) : Estimated height over the cylinder of the goal.
4.1.1 ALTIMETERS SETTINGS
Goto the “ALTIMETERS” menu and select which altimeter you want to adjust (A1
or A2). Important : while the recorder is activated is not possible to adjust the altimeter A1
When GPS signal is available, and barometric altimeter ALT1 is not been manually setted, it will be
synchronized with GPS altitude value.
To set manually ALT 1 altimeter with GPS altitude value press button
Important : while the recorder is activated is not possible to synchronize the ALT 1
The A2 altimeter is suitable for general purpose, to reset it press the
key (long pressure).
The A3 altimeter is automatically reset while entering in a thermal.
The altimeters can be shown in meters (mt) or feet (ft). Parameter (MAIN SETUP \ n. 13 U-AL).
4.2 VARIOMETERS
4.2.1 10 SENSORS VARIOMETER WITH SELF-ADAPTIVE SENSITIVITY
It's a revolutionary digital system designed by Digifly, based on a sophisticated data acquisition system
updated 100 times each second that merges 10 sensors : the atmospheric pressure sensor data with
the 9 sensors inertial platform data (3 accelerometer, 3 magnetometer and 3 gyroscopes).
This system is also equipped with a self-adaptive sensitivity that auto-modulates the instruments sensitivity
according to the airs situations: increasing it in weak conditions and decreasing it in strong conditions or
turbulences
This allows to get a vario with an high sensitivity and instantaneous response yet fluid and immune to the
turbulences and very helpful in weak conditions thanks to its pre-thermal function. Furthermore, in contrast to
the traditional variometers based on a pressure sensor only, it is not affected by false readings due to
accelerations.
Important Notes :
The mathematical method that manages the variometer as been optimized to obtain an
exellent response during fligths; for this reason we suggest to try or compare it flying and not on the ground.
Even though the system is totally automated it’s possible to manually force values of some filters (only for
expert users) :
o Filter 1, parameter (VARIOMETER SETUP \ n. 10 FLT1), default value 80% , (suggested range from 70% to
95%). Reducing this value makes the vario very sensitive to variations.
o Filter 2, parameter (VARIOMETER SETUP \ n. 11 FLT2), default value 72, suggested range from 48 to 96,
reducing this value makes the vario very sensitive to variations.
o Filter 3, parameter (VARIOMETER SETUP \ n. 12 FLT3), default value 0%, suggested range from 0% to 10%
o Filter 4, parameter (VARIOMETER SETUP \ n. 13 RVAR), default 0. Increase this value to reduce reactivity.
