Features

• Airliner-style bar display or retro-style pointer display
• TE variometer with optimized Kalman filter, adjustable range and damping
• Barometric altimeter with QNH setting or QNH autosetup (airfield altitude as default)
• Speed display (IAS or TAS) with speed command (S2F)
• Adjustable wing loading and MacCready value
• Built-in speaker with volume control, power 3 watts
• Sound individually configurable (height, chopping, dual tone, deadband
• Flaps display with optimal position according to ballast, airspeed and the load factor
• Extensive polar library with over 100 common polars
• Polar can be modified later
• Digital compass with external magnetic sensor (21 series)
• Wind calculation in circular flight and with compass also straight flight (TAWK method, in development)
• MacCready, ballast and bugs setting option
• stall warning
• Outside temperature display with external sensor
• Battery charge status display, voltages configurable
• Wireless Bluetooth V4.2 (classic BT) or standard WLAN access point for external devices
• 2x RS232 TTL interfaces, S1 with standard cable in IGC standard, S2 socket in IGC standard
• High accuracy barometric altimeter
• Sunlight readable, bright and high-contrast 2.4 inch IPS display with 57 mm diagonal
• Switch input for vario/set speed changeover (switch or button adjustable)
• Simple setup menu using rotary switch with push and turn function
• Light and small device avail for standard 57 mm instrument cut-outs, housing depth only 35 mm
• Elegant and robust CNC milled mat black anodized aluminum housing (shielding, low EMI)
• Software update via WiFi ‘Over The Air’ (OTA) when installed for new feature
• Analog input for flap display
• As an alternative to the flap display, landing gear warning via the same input
• Full FLARM Bridge for task declaration in IGC Flarm, flight download and FLARM setup

From the 2021 series, the following 3 new hardware features have been added:

• Audio power now 2 watts, better sound at high volumes
• Second serial RS232 TTL interface S2, IGC standard assignment and DTE and DCE support (RX/TX pins exchangeable via software)
• Input e.g. for a flap sensor or an undercarriage warning
• Optional feature: Attitude and Heading Reference System (AHRS): 6-axis direction and attitude sensor with 3-axis gyroscope and 3-axis accelerometer

From series 2022:

• In addition, a CAN bus interface on S2 for connecting a second two seater device, a CAN magnet sensor (from October 2022), as well as future extensions.

From series 2023:

• Temperature control for the AHRS chip for improved long-term stability
