Cold Protection and Manual Performance Assessment of Aircrew Gloves

INTRODUCTION: Military aircrew of rotary-wing aircraft often report cold and dysfunctional hands during cold-weather flying. Therefore, the cold protection and manual performance of in-service gloves was quantified in a laboratory study to support cold-weather advice to aircrew and glove procurement activities. METHODS: There were 8 civilian men who undertook a 60-min thermal test simulating the metabolic cost of rear crew physical tasks and wearing representative clothing on 15 occasions, where 3 main glove types (Cape leather, C; Cape + silk liner, C + S; Gunner, G) and 5 air temperatures (TA; +20, +10, 0, -10, -20°C) were assessed. Physiological (including mean finger skin temperature, TFSK), subjective thermal, and manual performance (including bare-hand and gloved finger/hand dexterity) measures were obtained. RESULTS: At a TA of 0°C, mean TSKF was 15.2 (C), 17.9 (C + S), and 22.4°C (G). Finger cold discomfort occurred at a TA of 0°C in C, and at -10°C in C + S and G. Gloved finger/hand dexterity was impaired relative to bare hands by 46/4 (C), 56/14 (C + S), and 73/44% (G). There was no relationship between TSKF and dexterity performance. DISCUSSION: The performance of aircrew gloves has been baselined for male aircrew. Cape leather gloves are limited to a TA of +10°C. Adding silk liners and wearing the Gunner glove extended exposure down to a TA of 0°C but imposed considerable impairment on dexterity performance. Solutions are required to enhance cold protection at a lower cost to manual performance, which must demonstrate applicability to both male and female aircrew. Weller AS, Boyd JWR.
