The Altitude Indicator A-034-4-16 is a pointer-type height indicator used as part of the A-037 radio altimeter system to display the true altitude of an aircraft above ground or water.

A member of the unified A-034-4 family, the A-034-4-16 is structurally identical to other indicators in the series, differing only in display range and scale graduation.
This version provides altitude indication from 0 to 750 meters, making it suitable for low- and mid-altitude flight operations.

The scale is divided into three measurement zones for improved precision near the ground and simplified reading at higher altitudes:
— 0–20 m — 2 m increments
— 20–100 m — 5 m increments
— 100–750 m — 50 m increments

The instrument includes a danger altitude adjustment sector, an integrated warning lamp and a drop-out blinker flagthat appears when the altimeter becomes inoperative or loses ground reflection.

A front-panel TEST button allows cockpit verification: a serviceable system moves the pointer to the reference value; in the absence of response, the blinker is shown.

The A-034-4-16 mounts on the aircraft instrument panel and operates together with A-037 series transceivers and antennas.
