Airspace class is a category used to divide the sky into different zones, defined by both geographical boundaries and altitude levels. The International Civil Aviation Organization (ICAO) provides standardized airspace classifications that most countries follow. The classification dictates the level of control and services provided to aircraft operating within that airspace. However, nations may choose to implement only certain classes and modify the associated regulations and requirements to suit their needs. Additionally, countries can establish special use airspace (SUA) zones with supplementary regulations to address national security concerns or safety considerations.
