LTRI PAST INVESTIGATIONS OF LIGHTNING HAZARDS AND PROTECTION OF MULTI-JET AIRCRAFT HAVE BEEN REVIEWED FOR APPLICATION TO THE KC-135 and similar type aircraft. Flight experiences of commercial jet operations have been utilized in determining economics as well as possible hazards. Use of protection conductors for the nose radome is recommended as economic as well as effective in reducing a slight hazard. Lightning protection systems of some type or at least a review of present systems, is recommended for all antennas leading into the fuselage. Current studies of possible streamer and lightning stroke hazards to fuel vents suggest the application of lightning diverter systems. No serious hazard is anticipated from most honeycomb construction. Consideration should be given to possible precipitation-static radio interference from lightning protection devices and in some cases they can be used to reduce this type of interference. Suggested for further study are the possibility of entry of DC lightning stroke components into the aircraft interior, lightning hazards from some types of full gage and fuel tank filler caps and electrostatic hazards from fuel tank liners.
