Analysis of the facial measurements of Korean Air Force pilots for oxygen mask design

Abstract

This study measured the facial dimensions of Korean Air Force(KAF) pilots, to design a pilot oxygen mask, and compared them with those of Korean civilians and US Air Force (USAF) personnel. Twenty-two facial dimensions were measured for 278 KAF male pilots (KMP) and 58 KAF female pilots and cadets (KFP) using an anthropometer and a three-dimensional scanner. The KMP face measurements were found to be significantly larger (mean difference, (d) over bar = 0.7-26.5 mm) and less varied (ratio of SDs = 0.29-0.82) than those of Korean male civilians. The average face length, lip width and nasal root breadth of the KMP were significantly longer ((d) over bar = 4.7 mm), narrower ((d) over bar = -22.4 mm), and wider ((d) over bar = 5.2 mm), respectively, than those of USAF male personnel. Lastly, the KMP face measurements were significantly larger ((d) over bar = 1.8-26.1 mm) than those of the KFP.
