Repair or replacement of a transparency mounted in body of a vehicle, e.g. an aircraft when one or more properties of the transparency is (are) operating outside of an acceptable limit(s) is arranged by monitoring operating performance of a property of the transparency, e.g. by mounted a sensor, e.g. a sensor for detecting moisture; a sensor for detecting impacts and vibrations; a sensor for detecting fractures; a sensor for detecting electric arcing, and a sensor for measuring temperature of an electrically conductive coating, on the transparency. Scheduling repair or replacement of the transparency at a geographical area when the operating performance of the property is outside an acceptable operating performance limit, and forwarding the schedule to the vehicle and to a maintenance location to prepare for the repair or replacement of the transparency at the geographical work area.
