Instruments_Altimeters_MGL_MGL-AVIONICS-ALT-4-ALTIMETER

The ALT-4 is a 3 1/8” instrument that contains a precision encoding altimeter and a wide range vertical speed indicator. The altimeter conforms to ANSI standard atmosphere rules from –700 ft up to a maximum of 30 000 ft. The altimeter can display altitude in feet or meters and local pressure can be set in millibars or inches of mercury. The ALT-4 also provides a transponder compatible Serial RS232 and parallel gillham code output.  The onboard VSI indicator is altitude compensated and can be displayed in either feet/minute (ft/min) or meters/second (m/s). It also offers a digital readout with a wide range from +/-20 ft/min to as high as +/-10 000 ft/min, it also offers a logarithmic analog display with a +/-2000 ft range. The VSI can be calibrated by the user once the instrument has been installed in the aircraft.  In addition the ALT-4 provides an OAT sender which is used in determining the density altitude of the aircraft. The ALT-4 can also be used to measure relative altitude and it has a facility for the pilot to enter a reference altitude and deviation band that has to be kept. Download ALT-4 Manual PDF
