1. A method of operating an apparatus which has at least two alternative operational modes, and a plurality of controllable operating devices, the controllable operating devices being operable by the operator, and the apparatus further including a controller to which demand signals to operate the controllable operating devices are input by the operator from a main operating control structure, and from which command signals are issued to the controllable operating devices, to change the operating states of the devices, and the apparatus further including an advisory device, and an auxiliary control structure for the operator to input an auxiliary signal to the controller, the auxiliary control structure being operationally separate from the main operating control structure, at least one of the operating devices having an expected operating state appropriate for an operational mode, the method including determining the operational mode in which the apparatus is being operated or is about to be operated, determining the operating state of the at least one operating device, comparing the determined operating state with the expected operating state and where the determined operating state is not the expected operating state, the controller providing an indication to the operator by the advisory device, and permitting the operator to change the operating state of the at least one operating device to the expected operating state using the auxiliary control structure.
