What are the procedures for flight checking a glideslope and localizer? What are the FAA and ICAO requirements and procedures for flight checks and calibration of glideslope and localizer transmitters? I'm interested in both the engineering and piloting aspects.
It's all laid out in Order 8200.1D United States Standard Flight Inspection Manual.    

That and other documentation, including the inspection reports can be found from the FAA website under Flight Inspection Information.
