2 GETTING STARTED
2.1 CONNECTIONS
The dual purpose mini USB socket allows the Digifly AIR to be recharged via the supplied Digifly 5v charger and
additionally connection to a personal computer or to a MAC for configuring & managing flight data.
Micro SD card slot. Bluetooth connection (AIR-BT only).
2.2 BATTERY
The main power is supplied by an internal rechargeable high capacity lithium battery, that has no memory effect,
so it can be partially recharged, without affecting the battery’s life. It also has a very low self-discharge rate
(more than one year) and works very well at low temperatures. A fully charged battery will power the instrument
for over 30 hours.
When the battery’s icon starts to blink there are roughly 4 hours of battery life remaining.
2.2.1 BATTERY RECHARGE
To recharge the instrument insert the charger plug or other mini USB accessory The required time for a full charge is about 8 hours. There are no problems if you leave the vario charging for more than 8 hours, as the vario automatically switches
to a “maintain mode” which prevents the battery from being overcharged.
The Digifly AIR’s lithium battery has no “memory effect”, so it can be also partially charged.
2.2.2 EXTERNAL POWER SUPPLY
The mini USB socket can be used to power the instrument and simultaneously charge the internal battery.. An external stabilized 5VDC power supply (e.g. a solar panel) with a minimum of 150mA is necessary to turn on
the instrument. Any excess power will be used to charge the internal lithium battery. Proper solar panels are
suitable to power the instrument.
2.3 KEYBOARD - NORMAL OR LONG KEY PRESS
The time length you keep the keys pressed on your Digifly instrument selects the available functions. For a Normal key press : press the button for less than a second For a long key press : keep the button pressed down for at least 2 seconds When not specified, the key press has to be considered as a normal key press (less than a second).

In the
MASTER INFO GPS page, are visible all values relative to your GPS position and particular fuctions available only
on this layout: function “take me here” (GOTO HOME), function “save current position” (MARK), function “cancel current
navigation” (CLEAR NAV) and supervision real time function "Real Time Navigation Manager" of progress active route
with the chance to go back and forth through WPT (function "Skip Waypoint").
3.5.1 GPS STATUS INFORMATION
The GPS icon signal has different meanings:
- GPS icon on steadily = Correct GPS FIX (GPS position available)
- GPS icon blinking = poor signal (GPS position NOT AVAILABLE)
3.5.2 LATITUDE & LONGITUDE COORDINATES
The latitude and longitude coordinates are shown in the top part of INFO GPS page and are referenced as map
datum WGS84.
3.5.3 LATITUDE & LONGITUDE COORDINATES OPTIONS
There are available 3 different types of coordinates:
DMS = degrees, minutes and seconds (dd° mm’ ss.s) (default)
DMM = degrees and minutes (dd° mm.mmm’)
UTM Universal Transverse Mercator (utm x, y, zona).
To set up the chosen DMM , DMS o UTM utilizzare il parametro (ADVANCED SETUP \ n. 22 CORD).
3.5.4 GPS SIGNAL QUALITY (HDOP)
The HDOP value represents the weakning of GPS signal. Small values mean good precision.
3.5.5 GPS ALTITUDE
GPS altitude (“ALT GPS”) represents the heigth over sea level given by the GPS system.
3.5.6 GPS DIRECTION (TRK)
GPS direction (“TRK”) represents the aircraft direction relatively to ground.
3.5.7 GPS GROUND SPEED
The GPS ground speed is the aircraft speed relatively to ground (“Gs”).
3.5.8 REAL TIME NAVIGATION MANAGER / SKIP WAYPOINT
The central part of the GPS INFO page shows in real time navigation progress of active route; is shown a
waypoint list of active route, highlighting in "reverse" the current one.
With the "Skip Waypoint" function is possible to move back and forth from the current waypoint:
only from GPS INFO page , if the navigation to route is active, press the button
(long pressure) ,and a menu
will appears , press button
to jump to previous Waypoint or press to jump to following Waypoint or press
to cancel.
In case is active navigation to a singol waypoint, the central part of GPS INFO page will show only the name of
current waypoint.

3.5.9 CREATING A NEW WAYPOINT USING THE CURRENT POSITION (MARK)
"MARK" function : when the GPS acquires a valid position it is possible to save it in the instrument’s memory.
From the GPS INFO page press the key
(long press) , the message " Save Mark ?" is shown, press the
key to confirm or press the
key to annul. The current position will be saved as a new Waypoint in the User
Waypoint list (“WPT USER”) with the format nnMaaa (aaa= altitude GPS in tens of meters)
3.5.10 NAVIGATION TO WAYPOINT HOME (GOTO HOME)
Available only in the GPS INFO page, ensures that the instrument guides us back to the point where we
activeted this function.
It’s particular useful, for example, when we go flying in a new site of which we don’t have waypoints and we want
to get guided to the landing zone . In this case is necessary to go to the landing zone and activate this function.
How activate the "GOTO HOME" function : from the GPS INFO page, wait till the GPS position is valid, then press
the
key (long press) , the message " Activate Home Wpt ?" is shown, press the key to confirm or press
the
key to annul.
Note : if a navigation has already been previously activated, first of all is necessary to deactivate it : from the
GPS INFO page press the
key (long press) , the message " Clear Nav ?" is shown, press the key to
confirm or press the
key to annul.
The "GOTO HOME" function creates a landing waypoint in the User Waypoint list (“WPT USER”) with the current
position data “HOMaaa” (aaa = GPS altitude in tens of meters) and with the icon "A" (airfield) and at the same
time activates the navigation (GOTO) to it.
3.5.11 DEACTIVATING THE CURRENT NAVIGATION (CLEAR NAV)
Function "Clear Nav" : to disable current navigation, press button (long pressure) , " Clear Nav ?" will
appear, confirm with button
or press to cancel.
3.5.12 DATE & TIME
Date and current time get automatically updated with GPS data when you start the instrument. To set your country time zone (MAIN SETUP \ n. 7 UTCO). To manually change date and time (MAIN SETUP \ n. 8 HOUR), (MAIN SETUP \ n. 9 MIN), (MAIN SETUP \ n. 10
DAY), (MAIN SETUP \ n. 11 MONT), (MAIN SETUP \ n. 12 YEAR)

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.
