Air Glide VT-01

VT-01 – The flexible 57mm Transponder

The VT-01 series of transponders are modern Mode-S/ADS-B transponders for panel installation in the form factor of a standard 57mm (2,25″) instrument. Two output power classes and two housing variants are available. The VT-01 is our most versatile transponder and a cost effective solution for any type of aircraft.


Simple Installation

VT-01 is available in a compact and lightweight version, the VT-01 ULTRACOMPACT or as a two-block system with two separate units, a control- and a main unit called VT-01. Installation is easy even in the most space constrained cockpits. The integrated altitude encoder (alticoder) can be set up to 100ft or 25ft resolution, external alticoders are not required.


Low power consumption

Due to its low power consumption, the VT-01 draws only 0,25 to 0,45A of current at 12V, the VT-01 is a good choice for aircraft with limited energy supplies like gliders, microlights or balloons.

Use ADS-B today

VT-01 is capable of sending out ADS-B data without modifications. ADS-B data can already be utilized by many collision warning systems. The only thing required is the connection of a normal NMEA RS232 GPS-source which is available in nearly any aircraft.

Flexible Installation

The VT-01 can be installed in a single block or in two blocks with separate main- and control-unit. With up to 10m cable lenght it is possible to for example install the main unit near the antenna in the rear part of the aircraft and the control unit inside the cockpit. VT-01 can be used together with AIR COM radio transceivers eliminating the need for a second control-unit in the panel.

VT-01The main-unit is installed in a special mounting kit and can easily be removed/exchanged without modification of aircraft wiring. This solution is ideal for clubs who want to share one main unit in different aircraft or operators with demand for high availability and easy maintenance.
