Observed impact of traffic and weather on continuous descent and continuous climb operations

• Arrival demand capacity ratio influenced both CDO and CCO execution and a 20% percent increase results in a decrease in the likelihood of ✦ CDO execution by 10% ✦ CCO execution by 8% • Weather and holding had negative impacts on both CDO and CCO execution, although impacts are higher for CDOs ✦ For each additional holding flight, likelihood of CDO decreased by 3% ✦ Presence of bad weather reduced the likelihood of CDO execution by 8% • Procedure use is high, but doesn´t influence the execution of CDOs and CCOs
