It is presented here the time domain model of the termimal approach, which describes the procedure how two independent random flows of air-traffic are led to the final approach and landing. The model can cover, basically, any actual ATC (air traffic control) procedure, e.g. multipath, radar vector and velocity control. Taken various traffic parameters into consideration, simulations are preformed for modified models, which are classified into 9 classes according to the number and composition of ATC instructions. Results are evaluated from viewpoints of the average delay and the alarm rate (the frequency that the conflict occurs). Obtained data can be used to clarify the relations between the evaluation parameters, mentioned above, and the flight accuracy, for any actual ATC procedure.
