A-034-4-13

The Altitude Indicator A-034-4-13 is a pointer-type cockpit instrument used as part of the A-037 Variant 11 radio altimeter system.
It provides real-time display of true height above ground or water and is optimized for low-altitude flight operations where precise vertical awareness is critical.

The instrument features a high-resolution scale from 0 to 750 meters, allowing the crew to monitor altitude visually throughout the full operating range of the radio altimeter.
A built-in TEST function enables verification of system operability: when the TEST switch is activated and the radio altimeter is serviceable, the pointer moves to a specified test reference value. If no movement occurs or if a fault is detected, a drop-out blinker flag appears on the indicator scale.

A combined rotary control mechanism allows pilots to set a danger altitude threshold. When the aircraft descends to or below the selected height, a dedicated warning light activates to alert the crew of hazardous flight conditions.

The indicator is integrated into the A-037 Variant 11 system, which includes a A-037-1A transceiver, two AR5-1 or A-037-2 antennas, wiring harnesses and mounting components. The altimeter system operates within the designated frequency band and delivers continuous altitude information in standard flight environments.
