A commercial aircraft battery management system is a critical component in aviation that is responsible for managing and monitoring the health and performance of the batteries used in aircraft. These batteries serve various essential functions in commercial aircraft, such as providing backup power, emergency power for critical systems, and powering auxiliary equipment on the ground.

Tires are an integral part of an aircraft and are produced using various components such as synthetic rubber or natural rubber, with addition to carbon black and nylon tire cord fabric. The durability of aircraft tires depends on the aircraft models (endurance varies between 30-200 landings). However, by introduction of new-generation radial tires, the events of tire wear out are expected to decline.

Trolleys are used in industrial, airports, hospitality, and other applications to move goods from one place to another. Vendors manufacture different types of trolleys depending on the needs of the target industry.

The train collision avoidance system (TCAS) offers a warning or situational awareness that is specifically designed to prevent train collisions. Such systems are also extensively used in the mining and automotive sectors, apart from the railways sector, to avoid accidents caused by collisions. These are not specific to train mounting and can be deployed on railway tracks, crossings, and track-changing junctions.
