NOTAM (Notice to Airman) is a notice distributed by means of telecommunication which concerned with the establishment, condition or change in aeronautical facility, service, procedure or hazard. The timely knowledge of NOTAM was essential to persons who concerned with flight operation. In order to improve the transmission efficiency of NOTAM, ensure the timeliness and effectiveness of NOTAM distribution service, this paper applied the publish/subscribe model to the NOTAM distribution service, and modeling it based on petri net, analyzing the properties with boundary and conservation of the model using the P-invariant analysis method. Which verifies that the NOTAM distribution service model is correct and effective.
