As specified by the Geneva Conventions, aircraft of the ICRC are marked with the Red Cross insignia on a white background. This marking is displayed on the rear fuselage sides and often also on the fuselage belly, wing centre section or outer wing. In addition, the aircraft are normally painted white overall, although this is not compulsory under the conventions. The operator titles ICRC are displayed on the forward fuselage, often with the circular COMITE INTERNATIONAL GENEVE marking. Alternatively, the latter is displayed on the tail fin.
