The global aerospace industry can broadly be categorized into two sectors, commercial and defence. Both use components in safety critical applications, making inspections of these parts are vital.
The commercial aerospace sector consists of companies that produce large commercial aircraft, regional aircraft, light aircraft (such as helicopters and business jets), aircraft engines, parts and auxiliary equipment, and commercial satellites. Dominated by Boeing in the United States and Airbus in Europe, the primary end customer is the global airline industry.
The defence aerospace sector is comprised of companies that produce aircraft, engines, parts, equipment, weapons systems, and military satellites.
Major companies in the sector include Lockheed Martin, Rolls Royce, Airbus, Martin Baker, Northrop Grumman, Raytheon, Boeing, General Dynamics, and BAE Systems. Demand is driven by defence spending.
Subcontractors manufacture a huge range of components that are supplied to these aerospace companies that range from sensors, connectors to turbine blades and electronic systems.
