1. A sensing device for monitoring an aircraft brake assembly, the sensing device comprising:
a housing configured to be rigidly connected to the chassis of the aircraft brake assembly, the housing comprising a displacement sensor; and
a pin extending through the housing and comprising a first end configured to move with a pressure plate of the aircraft brake assembly such that, in use, the pin is configured to move relative to the housing in a longitudinal direction of the pin;
wherein the pin comprises a detectable element portion positioned within the housing and comprising a first end and a second end and wherein the displacement sensor is configured to monitor the position of the detectable element portion within the housing,
wherein the pin comprises a temperature sensing portion located between the first end of the detectable element portion and the pressure plate and configured to monitor a temperature of the pressure plate, and
wherein the pin comprises a visual wear detection portion located proximate the second end of the detectable element portion and extending from the housing in a direction away from the pressure plate and configured to indicate wear of brake discs in the aircraft brake assembly.
