However, there are still minimum weather conditions that must be present in order for the aircraft to take off and land ; these will vary according to the kind of operation, the type of navigation aids available, the location and height of terrain and obstructions in the vicinity of the airport, equipment on the aircraft, and the qualifications of the crew.
