In order to design the RNAV (area navigation) precision approach (PA) or nonprecision approach (NPA) there is a need to collect vital information on runway, aerodrome obstacles, and other important factors that support approach and landing procedure. Therefore, the development of RNAV flight procedures requires the acquisition of relevant field data on objects that affect flight safety during its decisive stages. Designing of flight procedures, updating aerodrome maps and aerodrome obstacle maps, creating obstacle...
