A method of suppressing contrails 4a emitted by a propulsion system 3 of an aircraft 1. A first fuel composition is fed into the propulsion system for a predetermined period of time in a step a. The expiry of the predetermined period of time is detected with a timer 18 in a step b. Upon expiry of the predetermined period of time, a second fuel composition is fed into the propulsion system in a step c. 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 a-c are repeated.
