A probe (118) is provided for use in determining at least one characteristic of contents within a fuel tank. The probe (118) includes a plurality of analysis elements (302). Each analysis element (302) has an input (308) for inputting light to a sampling region (316) to be analysed and an output (310) for outputting light that has passed through the sampling region (316) from the input (308). A system including a probe (118) and a spectrometer (406) is also provided. The probe (118) may be mounted to a interior wall of an aircraft fuel tank, or to a rib (112,116) within an aircraft wing (104,106). |
