OAS Surface Optimization of Shuangliu Airport based on Collision Probability Calculation

Airport clearance safety management is an important part of airport operation indicators. Controlling obstacle height is one of the most important tasks in airport clearance management. The current program design and evaluation in China currently uses the obstacle restriction surface (ILS) and Obsta...

description Airport clearance safety management is an important part of airport operation indicators. Controlling obstacle height is one of the most important tasks in airport clearance management. The current program design and evaluation in China currently uses the obstacle restriction surface (ILS) and Obstacle Evaluation Surface (OAS). The current program design in our country rarely uses the collision risk mode (CRM), but the obstacles around the airport are gradually increasing. At this stage, the OAS surface is more conservative. A simplified model with a collision probability of approximately 1×10-7 is constructed and compared with the OAS surface to improve it. The results show that the slope of the original OAS surface is larger than that of the simplified model. The improved OAS surface meets the target safety level and solves the problem of being too conservative.
