UA27A-13 Inertial Sensor Overview

The UA27A-13 inertial sensor is a compact aviation device designed to detect inertial loads and generate an electrical signal when a predefined overload threshold is reached. The sensor is used in aircraft systems where monitoring of acceleration and overload conditions is required. It operates as part of onboard control, safety, and flight parameter monitoring systems installed on various types of aircraft and helicopters.

UA27A-13 Sensor Function

The UA27A-13 inertial sensor performs automatic detection of critical acceleration levels during aircraft operation. When the specified overload value is reached, the sensor triggers an electrical contact signal that is transmitted to connected onboard systems. This signal can be used for activation of protective systems, automatic control logic, or recording of flight parameters in monitoring equipment.

UA27A-13 Aviation Application

The sensor is widely used in aviation equipment installed on transport aircraft and helicopters. It is known to be applied in onboard systems of aircraft such as the L-410 Turbolet and the An-26, where it forms part of systems responsible for flight data monitoring, safety logic, and automatic control of certain subsystems.

UA27A-13 Operational Context

Within aircraft systems, the sensor is installed on a rigid structural element of the airframe and oriented according to the required acceleration measurement axis. The device operates reliably under typical aviation environmental conditions, including vibration, humidity, and pressure variations. The product is also known under alternative designations UA-27A-13, УА-27А-13, which refer to the same product type.
