the air traffic control system (ATC) is a safety, monitory and environmental critical system in a sense that its malfunctioning may cause the loss of human life, serious injuries and financial disasters. To ensure the safety of such systems it requires advance methodologies and step by step design process. In this paper, we have used formal methods in term of VDM++ to specify the safety properties of ATC system. the VDM++ is an object oriented modular based mathematical technique used to specify and verify the software systems. the method ensures the correctness by identifying errors at early stages of systems designing. the ATC system can be divided into three parts, i.e., departure, flight and arrival procedures. In this paper, we restrict ourselves to the air craft arrival procedure which consists of two stages of the control system. At the aircraft landing, it is controlled by the local controller then it is transferred to the ground controller. Initially, the related safety properties are specified then it is checked the syntax, type and flow by using the VDM++ toolbox.
