ALT-7

ALT-7 Precision altimeter and VSI indicator

The ALT-7 is a 3 1/8” sunlight readable encoding altimeter and a wide range vertical speed indicator. The altimeter contains an internal high accuracy 24 bit digital altitude sensor which calculates altitude from -1000 ft up to a maximum of 35000 ft. The ALT-6 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.

The ALT-7 also features a user-set altitude bug and an encoder test function. The ALT-7 also integrates a Gillham parallel altitude encoder output for legacy transponders
