A method of suppressing contrails emitted by a propulsion system of an aircraft. A first fuel composition is fed into the propulsion system for a predetermined period. The expiry of the predetermined period is detected with a timer. Upon expiry of the predetermined period, a second fuel composition is fed into the propulsion system. The second fuel composition is more prone to cause contrails than the first fuel composition. Contrails generated by the propulsion system are detected as the second fuel composition is fed into the propulsion system. If a contrail is detected, the steps of the method are repeated.
