Abstract:

With the rapid development of aviation transportation,route network becomes more and more complex,the number of route crossing point is increasing,influencing the route capacity. It is more and more privotal to calculate the route crossing point capacity accurately. Based on route crossing point and route capacity models,new models are built. The influences of aircraft combination,crossing angle and longitude on capacity are analyzed. The crossing point of H139 and H142 is taken to simulate these models. Results show that when the velocity of aircraft in front is larger than the aircraft behind,the route crossing point capacity is biggest;when the route爷s longitudes are same,the route crossing point capacity is increased with the increase of crossing angle;when the crossing angles are same,the route crossing point capacity is increased with the increase of longitude;the route capacity in the situation of flight level changing is decreased by 9.1%.

Key words: route crossing point, capacity model, crossing angle, route length, aircraft combination, flight level change
