航空機の運航における定時性の一解析

Punctuality gives an indication of delay from schedule on aircraft operation. Improvement of punctuality is one of the important topics for future ATM (Air Traffic Management) plans. To improve punctuality, it is indispensable to comprehend current state of delay. In this paper, delay analysis results from actual data of Japanese aircraft operation are presented. Firstly, punctuality on Japanese principal airports is studied. In addition, the punctuality is studied seasonally and weather impact on punctuality is briefly discussed. Moreover, aircraft operation is divided into the four phases to study delay in detail. Defining standard times, delay is computed for each phase. To spot the operation phases that incurred longer delay, the computed delays are compared.
