The ASX-2 altimeter/airspeed combo is a 80 mm instrument based on a precision altimeter and a wide range, sensitive airspeed indicator. The altimeter conforms to ANSI standard atmosphere rules from –700 ft up to a maximum of 30,000 ft.
The altimeter includes an encoding serial output that, when used in combination with MGL Avionics CNV-AT, provides a parallel Gillman code interface for transponders. The altimeter can display altitude in feet or meters. Local pressure can be set in millibars or inches or mercury.
The airspeed indicator can show air speeds from 16 to 250 mph and is well suited for use in slow aircraft due to very good sensitivity and linearity at low air speeds. The airspeed indicator as well as altimeter can interface to a static port and the airspeed indicator is based on a standard aviation pitot tube. The airspeed indicator can be set to indicate speeds in statute miles per hour (mph), kilometers per hour (km/h) or nautical miles per hour (knots) with the air-distance being displayed in corresponding units. The airspeed sensitivity can be calibrated by the user to cater for errors caused by pitot tube placement. The ASX-2 also outputs airspeed information via the airtalk protocol for interfacing to the Infinity FF-1/Velocity FF-3 (fuel flow computer for single or dual fuel tanks) and the SP-X (AHRS) instruments.
In addition the ASX-2 provides a 24 entry automatic flight log that stores the duration of each of the last 24 flights, an air-distance trip counter and a current flight timer. The ASX-2 is the ideal instrument for installations were panel space is at a premium.
