AIR Glide - A new take on soaring avionics
AIR Glide offers a unique
line-up of flexible, high quality and easy-to-use
soaring avionics. With AIR Glide there is no
distinction between „variometer“ and „glide computer“
in your cockpit anymore. It is all up to you: take a
Sensor Unit and any number of displays in any size and
combine them in any way you want.
AIR Glide devices share a common platform. This
product line strategy, that we have introduced with the
Butterfly Vario in 2011, allows for simple combination
and exchange of all AIR Glide devices. Existing
installations may be easily extended. Older units can be
exchanged against newer versions, for example if new
sensors become available, without the need for changing
the whole installation - reducing costs and securing
Our largest Display ("size L") has a 5.7" screen and
features variometer and speed-to-fly indication, moving
map navigation, comprehensive task planning, and
optimization as well as traffic awareness. It is
controlled via buttons or touchscreen and very easy to
The medium sized display ("size M") has a 3.7" screen
and features variometer and speed-to-fly indication,
moving map navigation, comprehensive task planning, and
optimization as well as traffic awareness. It can be
installed into existing 3.125" panel cutouts, requiring
only a 2.25" cutout itself.

Our smallest display is the perfect primary vario
indicator. It features variometer indication,
speed-to-fly indication, backup navigation, traffic
awareness, voice alerts, and artificial horizon. The
display can be installed into existing 2.25" panel
A new generation variometer
With a combination of 14 sensors, the relative
air-mass movement arround the aircraft is measured in
real time. This means big progress compared to normal
variometers, that only use pressure sensors to sense
aircraft/airmass movement. Independant of flight
direction the pilot sees real time air-mass and wind
data updated repeatedly every second. In many
flight-tests through 2011 pre-production devices have
already shown the potential of this new technology.
Giant display, easy to install
A new design concept integrates a device with big
2.7“ display into a small 57mm standard instrument
cutout. The perfectly readable display features a
contrast ratio similar to printed paper. It is readable
in any lighting condition and supersedes mechanical

digital compass, Butterfly FLARM®-Radar with
FLARM®-voice output, a robust artificial horizon with
true airspeed and true altitude, a fully certified IGC-flight-recorder
with many other features that simplify flying.
The heart of every AIR Glide installation. The sensor unit contains all
sensors and an IGC certified flight recorder. Computes vario, airspeed,
instantaneous wind, air mass movement, GPS-Position, magnetic heading and
The new design concept integrates a big 2.7" display into a
standard 2,25" panel cutout. The device is mounted from the front of the
panel. It is only marginally bigger than a standard 2.25" device and can be
easily mounted into any existing cockpit.
The very bright display depicts
all necessary information clearly arranged and bigger than common
variometers do. The display utilizes special anti-reflection technology
making it perfectly readable in *any* lighting condition.Its readability is
comparable to printed paper, making mechanical pointers obsolete.
Without mechanical pointers the displayed content can be made bigger and
it is possible to suit specific display requirements more flexibly.

All compatible devices, e.g. one sensor-unit and two display-units fpr
two-seaters, are connected through a standardized interface-system used in
professional airborne systems (e.g. Airbus A380 or Boeing 787) with robust
wiring called CANaerospace. Other display-units or larger screen devices can
be easily connected in the future. Butterfly Vario forms the foundation for
a whole new product family of gliding instruments from Butterfly. There is
no need for complex wiring.
Vario and speed-command
Vario, netto-vario and wind are accurately computed in realtime with data
from high tech sensors. A big black arrow-indicator shows the current vario
value. Vertical airmass movement is shown as a blue circle, average climb as
a smaller green arrow. Four freely configurable Info-Boxes show desired
The wind-arrow depicts the accurate live-wind. The built-in
three-dimensional compass always aligns the wind angle perfectly to the
roll-axis of the aircraft. This makes the wind arrow turn smoothly, even at
Indepandant of the chosen function-page, all needles are always visible,
also e.g. the navigation-page.
Artificial horizon and airspeed indicator
Butterfly Vario contains an artificial horizon. The horizon can be of
help in dangerous situations that may occur for example when there is
unpredicted cloud development during wave-flights. The horizon is a state of
the art, solid state precise instrument and can be compared to expensive
Butterfly Vario also features an accurate airspeed indicator with
TAS-indication as well as an accurate altimeter.
Horizon functionality can be deactivated in a tamper-proof manner.
The navigation function gives you directions to airports or turnpoints
from the integrated database. A very accurate final glide computer
calculates your glidepath based on wind, aircraft-polar, bugs, and current
The built in compass-sensor delivers exact true heading information. The
3D-compass is fully compensated and requires no set-up or calibration and is
not prone to compass errors. The navigation page is simple to use and
perfect as a backup or for basic navigation.
With our interface modules all generated datasets can be sent to other
devices like PNA/PDAs or wirelessly to iGlide.
FLARM®-Display and voice output
Our new vario communicates with FLARM® compatible devices. Traffic
information as well as tactical data is shown on a special radar screen.
A voice engine gives relevant information and warning messages in natural
voice. Voice messages are only given in dangerous or relevant situations.
They seamlessly enhance the pilot's workflow and do not distract.
If a dangerous traffic situation is imminent, Butterfly Vario warns in
clear natural voice: Warning. Glider, 12 O'Clock, High.
Voice output also gives you tactical hints, e.g. when a teampartner
behind you starts circling: Eight Yankee starts circling.
Through integrated sensors Butterfly Vario detects battery voltage,
gear-state, flap-state etc.
Butterfly Vario mixes other audio-signals (Vario, COM) with generated
voice messages or vario-tones. To ensure good transmission quality, all
vario-tones are reduced in volume during sending/receiving COM.
Up to two speakers can be attached to the vario, this is ideal for two
seaters and makes future implementations of directional voice-warnings

AIR Traffic Display - Enhance your traffic
AIR Traffic Display is our newly designed premium
display solution for traffic data. It features robust hardware, a sunlight
readable display and advanced functionality reducing flightcrew workload and
increasing traffic awareness. Air Traffic Display works well with many
collision avoidance devices like TRX, FLARM®, or systems with GARMIN® TIS
Works well with popular collision warning systems
There are many different collision warning systems on the market. AIR
Traffic Display is compatible to many systems, even if they are older. It
works with all FLARM® compatible systems, ADS-B-IN devices, and with systems
that use the GARMIN® TIS protocol. Its standard design fits into 57mm
(2.25") panel cutouts. AIR Traffic Display comes with a standard cable and
easily integrates into existing installations.
We have added a list of new and unique functions to increase safety. A
new radar symbology helps differentiating gliders from powered aircraft. The
new alert view helps to avoid misinterpretations in conflicting traffic
situations. Traffic is also monitored after signal loss with a tracking of
its probable position.
Traffic is indicated in a "radar-style" screen. The range can be adjustet
using a rotary knob from 500m to 32km radius. The own aircraft (magenta) and
other received traffic are shown with aircraft symbols.
Different types of traffic (powered aircraft, gliders, circling aircraft)
are shown with different symbols. Very high or very low targets are smaller
than targets in the same altitude as the own aircraft. Differential altitude
is directly indicated on the symbol (little plus or minus sign) - helping to
easily interpret the traffic situation.
New Alert View
The new alert screen has been designed as a result of current research.
It helps reducing potential for misconceptions, especially in situations
with high bank angles of the own aircraft. The screen is easy to interpret,
even for crews who are unfamiliar to flying with traffic warning systems.
Head-On Alert View
Conflicting head-on traffic is displayed using a unique "horizon-style"
indication that allows for quick and easy situation conception. The new
indication has been developed in cooperation with research facilities, with
the help of expert interviews and the help of surveys of several hundreds of
pilots. It can help to reduce reaction time in confliciting situations.
Targets on the radar-view can be selected using a rotary knob. Pilots can
actively select a target to review detailed target information such as
vertical separation or distance. The integrated database delivers in-detail
infos on targets such as registration or aircraft type. Targets of special
interest can be marked in different colors for easier recognition.
After losing the signal of a selected target, the target's last known
position is continuously monitored and displayed with increasing vagueness.
This helps keeping an eye on out-of-range-targets and estimating their
White on Black mode
The user interface can be switched to a dark mode. Especially when flying
at night, the dark user interface helps avoiding distractions. Some users
also prefer the dark user interface in daytime. Especially if other black
displays are used in the same panel, AIR Traffic Display shows a familiar
Sometimes airspace is really crowded, so is the display. Finding special
targets can take very long. AIR Traffic Display uses softkeys for fast and
convenient selection of up to four special targets like teammates or
