Compact tractors, generally known as compact utility tractors, are primarily useful for small farms. The compact tractors are designed for small-scale farming requirements. Based on capacity, the compact tractors are categorized into below 30 HP (Horsepower), 30 HP–40 HP, and 40 HP–60 HP. In terms of drive type, the compact tractors market is segmented into two-wheel drive and four-wheel drive. The agricultural sector is the major application area of compact tractors, followed by utility-scale applications.

The maintenance, repair, and overhaul (MRO) services are an essential and unavoidable aspect of every business. A proper MRO of an aircraft or its component can help businesses avoid significant risks to their survival. Thus, aviation industry players majorly focus on creating appropriate business processes and infrastructure to support industry growth. The rising demand for air travel worldwide is encouraging aircraft manufacturers such as Airbus and Boeing to increase their production volumes and offer maintenance services for these aircraft as well. With the constant growth in air traffic, carriers are more liable to maintain the optimum condition of the aircraft so as to extend their life span; otherwise, they would have to procure new aircraft. The cost of procurement of a new aircraft is much higher than the cost of the maintenance of the existing aircraft.

The airborne pods are an external pod structure primarily fabricated to offer enhanced aerial recognition, identification, communication, targeting, data linking, and self-defensive potentials to an aircraft. High-end airborne pods with a wide range of advanced sensors and laser technologies can operate in extreme weather conditions, which is also one of the prime factors boosting the application of airborne pods in advanced fighter jets, aircraft, unmanned aerial vehicles, and helicopters. The changing modern warfare scenario has forced governments of various countries across the globe to allocate substantial funds and financial aid toward respective defense and military forces. The growing defense expenditure budget indicates the government's emphasis and importance on modernizing the defense sector to meet the mounting need for security, which is one of the major market drivers.
