The Airport Land Use Assessment system streamlines the reporting of, assessment of and management of potential temporary and permanent obstructions which may affect the controlled airspace of an aerodrome. It is important to get an assessment report before engaging in any activity that could be a potential obstruction.

Why land use assessment is important :
Obstructions in the vicinity of an airport's aispace have the potential to create air safety hazards and to seriously limit the scope of aviation operations into and out of the airport. The operational airspace of airports is the airspace above a set of imaginary surfaces, the design of which is determined by criteria established by the International Civil Aviation Organisation (ICAO). These surfaces are established with the aim of protecting aircraft from obstacles or activities that could be a threat to safety.
The operational efficiency of safe operations at airports is affected by geographical features such as surrounding hills and artificial structures. These structures could affect the ability of aircraft to operate in the prescribed airspace in accordance with Visual Flight Rules (VFR). Tall structures and other activities that intrude into operational airspace have the potential to lower safety levels of aviation operations at airports. If these activities are not regulated, the aviation safety regulator may have to mitigate risk by placing restrictions on operations at affected airports.
