The Altitude Indicator A-034-4-11 is a pointer-type height indicator used as part of the A-037 radio altimeter system.
It provides continuous indication of the true altitude of an aircraft above terrain or water and is designed for operations at low, medium and extended low-altitude ranges.

A-034-4-11 belongs to the unified A-034-4-xx indicator family and is structurally identical to other models in the series, differing only in its measurement range.
This version displays altitude from 0 to 1000 meters, making it suitable for aircraft requiring altitude awareness beyond standard low-altitude envelopes.

The scale features three graduated segments with progressively reduced resolution at higher altitudes:
— 0–20 m – 5 m divisions
— 20–100 m – 10 m divisions
— 100–1000 m – 100 m divisions

The indicator includes a Danger Altitude setting sector, warning lamp, and a drop-out blinker flag, which appears when the radio altimeter detects a fault or loses reflection from ground surfaces.

A front-panel TEST push-button enables real-time system verification: a functioning A-037 system forces the pointer to the control value; absence of movement triggers the blinker.

The A-034-4-11 is installed in the cockpit instrument panel and operates together with A-037-1 series transceivers and associated antennas.
