| 1. A method of measuring a gas turbine engine operating parameter, said method comprising:
providing at least one engine component and a plurality of sensors;
positioning each of the plurality of sensors relative to an index location;
defining a periodic operating parameter distribution profile to extend across an engine component or between engine components;
receiving an operating parameter value from each of the plurality of sensors;
comparing each operating parameter value against the periodic gas flow operating parameter distribution;
determining if one or more of the plurality of sensors has failed; and
determining an operating parameter value for the failed sensor using the operating parameter distribution profile and the
received operating parameter values.
