Airplane de-icing technicians work from either an open-basket or closed-basket.
The objective of this study is to identify the tasks that have an influence on the physical fatigue of open-basket aircraft de-icing technicians.
In a Canadian airport during the winter of 2016-2017, a field study was conducted in which the heart rate of 12 volunteer participants was collected. The data was analyzed along with the 22 tasks that make up the activity of open-basket aircraft de-icing. For each participant, the mean absolute cardiac cost per task was compared. The evolution of the cardiac signal based on the resting heart rate and steady state limit was also characterized.
According to the cumulative results fatigue occurs for periodic tasks as well as double tasks. More precisely, the most physically fatiguing tasks are spraying de-icing and anti-icing fluids, moving the basket and truck, as well as tactile control and de-icing quality control at ground level.
Similar studies would need to be conducted in other aircraft de-icing facilities to improve the generalization of the results.
飞机除冰技术员在开放式或封闭式吊篮中工作。
本研究的目的是确定对开放式吊篮飞机除冰技术员体力疲劳有影响的任务。
在 2016-2017 年冬季的加拿大机场，进行了一项现场研究，收集了 12 名志愿者参与者的心率数据。对包括开放式吊篮飞机除冰活动在内的 22 项任务进行了数据分析。对于每个参与者，比较了每个任务的平均绝对心脏成本。还根据静息心率和稳态极限来描述心脏信号的演变。
根据累积结果，周期性任务和双重任务都会导致疲劳。更准确地说，最耗费体力的任务是喷洒除冰和防冰液、移动吊篮和卡车，以及在地面进行触觉控制和除冰质量控制。
需要在其他飞机除冰设施中进行类似的研究，以提高结果的概括性。
