The ASV-1 is a 2¼”” (57mm) sunlight readable encoding altimeter, airspeed and wide range vertical speed indicator.
The altimeter contains an internal high accuracy 24 bit digital altitude sensor which calculates altitude from -1500 ft up to a maximum of +35000 ft. The ASV-1 outputs various formatted RS232 serial data protocols compatible with serial input transponders such as that from Garmin, Magellan, Northstar, Trimble, Microair etc. The altimeter can display altitude in feet or meters and local pressure can be set in millibars or inches of mercury.
The VSI indicator can be displayed in either feet/minute (ft/min) or meters/second (m/s). The VSI can be calibrated by the user once the instrument has been installed in the aircraft.
Airspeed is based on the pressure generated by a pitot tube system and a static port is provided as well for use by high speed aircraft. The ASV-1 can measure airspeed from 20mph to 350mph* and is well suited to slower aircraft due to very good sensitivity and linearity at low air speeds. Airspeed can be indicated in statute miles per hour (mph), kilometers per hour (km/h) or nautical miles per hour (kts). The ASV-1 also provides a programmable Vs and Vne airspeed alarm output. ASI sensitivity can be calibrated by the user to cater for errors caused by pitot tube placement.
In addition, the ASV-1 provides an encoder test function, flight timer since takeoff and records the maximum airspeed reached. The ASV-1 provides a parallel Gillham code interface when used in conjunction with the MGL Avionics CNV-ALT.
