A method of generating a maintenance schedule for an aircraft 1 with gas turbines 10 powered by fuel F comprises determining one or more fuel characteristics and generating a maintenance schedule according to the one or more characteristics. A system 160 for performing the method comprises a fuel characteristic determination module 117 and a maintenance schedule generation module 162. The characteristic determination may comprise measuring a change in the properties of a sensor component exposed to the fuel, which may indicate a threshold level of fuel coking or surface deposit formation has occurred. The sensor component may comprise a piezoelectric crystal and the determination may be done by measuring a vibration parameter of the crystal. The sensor may comprise a seal material, and the characteristics may indicate whether a threshold level of swell of the seal material exposed to the fuel has occurred.
