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 Butterfly Vario 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 flying

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. Butterfly Vario forms the foundation for a whole new product family of gliding instruments from Butterfly.

Integrated 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 accurate results.

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 pilot does not have to circle or change direction to get the latest wind information.

Design and Installation
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 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. Butterfly Vario forms the foundation for a whole new product family of gliding instruments from Butterfly. There is no need for complex wiring.

Features in Detail

Vario and speed-command
Vario, netto-vario and wind are accurately computed in real-time with data from high tech sensors.

Display 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 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 high turn-rates.

Independent 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 certified solutions.

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 (if necessary for a soaring contest, etc.).

Important Note for U.S. Contest Pilots:
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 here:

Navigation
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.

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 team partner behind you starts circling: "Eight Yankee starts circling".

Through integrated sensors Butterfly Vario detects battery voltage, gear-state, flap-state etc.

Audio
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 possible.

IGC Logger and USB
Butterfly Vario 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.

Note: You will want to remotely mount the PowerFLARM's FLARM and ADS-B/Transponder antennas using an extension cable.  I will have them in stock soon in several lengths.  Since the GPS antenna is built-into the PowerFLARM, and it may not get good reception if mounted under other instruments in your panel, you may need to buy a remote GPS antenna.  I will stock those soon.  If the PowerFLARM is mounted at the top of the panel - you shouldn't need a remote GPS antenna and may not need to remote mount the FLARM and ADS-B/Transponder antennas - if you make a holes for them to stick up through the top of the instrument panel cover.
