1. A fuel characteristic determination system for determining one or more fuel characteristics of an aviation fuel for powering a gas turbine engine of an aircraft, the system comprising:
a sensor component formed from a nitrile seal material, a surface of the sensor component adapted to be exposed to the fuel;
a sensor arranged to measure a swell parameter of the seal material; and
a fuel characteristics determination module arranged to determine one or more fuel characteristics of the fuel based on the swell parameter.
