This paper describes a class of strategies for reducing persistent contrail formation with the capability of trading off between contrails and aircraft induced emissions. The concept of contrail frequency index is defined and used to quantify the contrail activities. The contrail reduction strategies reduce the contrail frequency index by altering aircraft's cruising altitude with consideration to extra emissions. The strategies use a user-defined factor to trade off between contrail reductiondoi:10.2514/1.c031680 fatcat:6lp35mlq3jc27lon7s5az2aiyu
