AIR Glide Variometer System
Starting with the AIR Glide vario system, Air Avionics launches a whole new
range of gliding products. The AIR Glide vario combines basic navigation,
Air Avionics display functionality as well as many other features with a
new technology variometer, based on current research projects and latest
sensor technology. It communicates with moving-map solutions and can be
easily integrated into existing cockpit layouts.

A new generation variometer
With a combination of 14 sensors, the relative airmass movement around
the aircraft is measured in real time. This means big progress compared
to normal variometers, that only use pressure sensors to sense
aircraft/air-mass movement. Independent 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 pointers.
More than just a vario
The AIR Glide vario system combines:
- Vario/Speed Command
- Basic navigation with waypoint
database (no tasks)
- Final-glide calculation
- Digital compass
- Accurate wind speed and direction
calculation - while cruising
- Butterfly FLARM®-Radar display
- FLARM®-voice output
- Artificial horizon with true
airspeed and true altitude
- Fully certified IGC-flight-recorder
- Many other features that simplify
Vario and sensors
Display- and sensor-unit are two separate devices. Both are connected
through a standardized interface-system used in professional airborne
systems called CANaerospace. Other display-units or larger screen
devices can be easily connected in the future. The AIR Glide Vario system forms the
foundation for a whole new product family of gliding instruments from
Sensor Unit (ISU)
Our Integrated Sensor Unit contains all sensors. 14 single
sensors detect changes in static-pressure, total-pressure, TE-pressure,
Temperature, 3D acceleration, 3D turnrate and direction through a
3D-compass-sensor. Additionally a built in state-of-the-art 60-channel
high-accuracy GPS receiver delivers accurate position data. This makes
the ISU a full-scale inertial measurement unit. All gathered datasets are processed in a
high-performance computer and deliver very accurate results.
The sensor system has been developed in
conjunction with university research activity that has been performed on
our hardware. The exact 3D-position of the aircraft is computed in
real-time, many times per second.
All used algorithms are field-upgradeable. Throughout the coming flying
seasons we will gather lots of user-data and experience and are going to
be able to further improve our software in order to provide even more

Real-time Wind and Airmass Info.
For the first time it is possible to measure and display wind as well as
airmass data in real-time.
- Many times per second the current
airmass-movement (netto vario) is detected and displayed on the
variometer scale as a blue circle.
- Our new "live-wind" delivers
accurate wind information that is updated many times a second. The

Design and Installation
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.
| Display Size Comparison
All compatible devices, e.g. one
sensor-unit and two display-units for 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. The AIR Glide Vario system forms the foundation for a whole new product
family of gliding instruments from Air Avionics. There is no need for
Features in Detail
Vario and speed-command
Vario, netto-vario and wind are accurately computed in real-time with
data from high tech sensors.
Items on the Vario page:
- A big black arrow-indicator shows
the current vario value.
- Vertical airmass movement is shown
as a blue circle
- Average climb is displayed as a
smaller green arrow.
- Four freely configurable Info-Boxes
show desired values.
- The wind-arrow depicts the accurate
- 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 high

all needles are always visible, also e.g. the navigation-page.
horizon and airspeed indicator
The AIR Glide Vario system 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 certified solutions.
The AIR Glide Vario system 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 (if
necessary for a soaring contest, etc.).
Important Note for U.S. Contest
Current U.S. soaring contest rules prohibit the use of any device which
allows flight without reference to the ground. So you would need
to remove this device or disable the artificial horizon while flying in
a U.S. soaring contest. I don't agree with this rule, but I do
recommend abiding by the rules. Their official policy is posted
http://www.ssa.org/files/member/Restricted Equipment Policy.pdf
In May of 2013 the U.S. Contest Committee OK'd the Butterfly variometer for use in U.S. contests as long as the artificial horizon feature has been disabled for the duration of the contest. Details are below:
The waiver and requirements (below) will be on the SSA website.
1. The presence of the instrument must be made known to the CD or Scorer prior to the first contest grid.
2. Prior to the first contest grid, the prohibited functionality must be disabled using the vendor's lockout mechanism for the entire period of the contest.
3. Prior to the first contest grid, the instrument version information and disablement must be shown to and verified by the CD, Scorer or their designee. Failure to comply with these requirements may be subject to a contest penalty.
John Godfrey (QT) > USA Rules Committee Chair
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 total-energy.
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.
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
If a dangerous traffic situation is
imminent, The AIR Glide Vario system warns in clear natural voice: "Warning.
Glider, 12 O'Clock, High".
Voice output also gives you tactical hints, e.g. when a team partner
behind you starts circling: "Eight Yankee starts circling".
Through integrated sensors the AIR Glide Vario system detects battery voltage,
gear-state, flap-state etc.
The AIR Glide Vario system 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
Logger and USB
The AIR Glide Vario system features a full-scale IGC-Logger (not yet IGC approved)
which is to be certified at the highest possible level.
It is possible to read-out IGC-files, declare tasks, update system
software or change settings via USB-stick.
