The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. The lancing mechanism includes a lancet carriage, a lancet holder slidably connected to the lancet carriage, and a lancet attached to the lancet holder. The position of the upper and lower surfaces of the base at each of the sample locations is determined by a confocal polychromatic displacement sensor. The control unit may perform a switch between a first fuel injection strategy and at least one further fuel injection strategy in response to a change in load demand on the engine. The method also includes accessing flight information stored on a remote server, and correlating the flight information to the passengers.
