IP52-03 / IP-52-03

Function of the IP52-03 indicator

The main function of IP52-03 is to show the crew the current state of a controlled mechanism on the aircraft instrument panel. The indicator receives discrete signals from limit switches or related position-sensing circuits and displays the corresponding condition through built-in light indication. This allows the crew to verify whether the controlled element is extended, retracted, locked, in transit or in an abnormal position, depending on system logic. The indicator is used where direct visual confirmation of the mechanism is not possible from the cockpit.

Displayed aircraft systems and controlled elements

In the supplied context, IP52-03 / IP52-03A is associated with Su-family combat aircraft, including Su-27 and Su-30 variants. Indicators of the IP52 series may display the position of landing gear, wing mechanization, airbrakes and automatic intake panels, depending on the aircraft and panel layout. Specific displayed states and legends depend on the version of the instrument and the aircraft wiring. Therefore, the exact function of a particular IP52-03 unit should be confirmed by the aircraft equipment list and cockpit panel documentation.

Indication logic and input signals

The indicator operates with discrete position signals from end switches or similar sensor circuits. According to the supplied context, input signals may come from switches such as VK2-200R or AM800K, depending on the controlled system. Green indication typically means that the controlled element is fixed in its required working position, while red indication may show an intermediate, unlocked or fault condition. Absence of illumination may indicate the element is retracted and locked, depending on aircraft circuit logic and the relevant technical manual.

Construction and cockpit installation

IP52-03 is described as a cockpit-mounted aircraft instrument in a compact metal housing. It is installed on the instrument panel and connected to the aircraft electrical system through a rear plug connector / socket. Mounting may be performed by flange screws or a retaining clamp, depending on the version and panel design. The instrument is intended for operation in cockpit conditions and must withstand aviation vibration and temperature loads typical of combat aircraft. Connector pinout and mounting dimensions should be confirmed by the official drawing.

Identification and ordering of IP52-03

Before ordering IP52-03 / IP-52-03, the buyer should confirm the exact designation, drawing / TU reference, aircraft type, required modification and documentation requirements. Related versions include IP52-03A, IP52-04, IP52-05 and IP52-16A, but they may differ by indication layout, input logic or application. The product may be required for cockpit indication repair, replacement of a defective position indicator, aircraft restoration or spare parts stock. Passport, acceptance marks, serial number and bench-test records should be checked before shipment.
