Abstract:Airport signs at certain critical locations at O'Hare International Airport and other major U.S. airports are being sheared off their mounting legs at the frangible coupling from aircraft jet engine blast and/or wake turbulence forces. his damage to the sign increases the chance of foreign object damage (FOD) as well as the loss of visual guidance for other aircraft. here is a need to better understand and more precisely determine the forces on the signs at these locations. The results of this testing indicated that the current frangibility design criteria is not adequate for airport signs installed on airports that service large transport aircraft. modification to the frangibility requirements or a maximum setback distance would appear to be a satisfactory solution to mitigate sign breakage. he former is recommended since it would appear to have no impact on the operational characteristics of the aircraft movement area.
