Paper 174 -- ANALYSIS OF MULTIPLE OPEN TRANSACTIONS AND CONTROLLER-PILOT MISCOMMUNICATIONS

This study addresses an important and common problem to both voice-based and data link systems: the problem of multiple open transactions and the occurrence of delayed responses in controller-pilot communications. The analyzed database includes forty-two 30-minute controller-pilot voice recording samples, derived from thirty-three sectors, positioned in five Air Route Traffic Control Centers (ARTCCs), and is used in modeling four Logit and Probit regression models. The study findings indicate that an increased number of multiple open transactions impacts the occurrence of miscommunications, and in particular the delayed responses by controllers. Since the message transaction time in a data link environment appears to be longer than in the voice-based environment, any further delays in message transactions with data link should be avoided because such transaction delays could make the data link system less efficient and productive.
