5 Dec 72 AC 20-82 CHAPTER 9. FH-227 AIRCRAFT WINDSHIELD FRAME 29% MAGNETIZATION CHARACTERISTICS. The windshield frame on the FH-227 is made of ferrous metal; thus the windshield frame becomes magnetized if the aircraft has an electrical discharge during an electrical storm. This, in turn, causes erroneous readings on the standby magnetic compass. The windshield, particularly the center post, should be checked periodically for being magnetized.
The windshield can be degaussed.
