ABSTRACT

Virtual reality (VR) simulation training for helicopter search and rescues (SAR) hoist operators is very uncommon in comparison to the availability of pilot simulation training. SAR hoist operators control winch systems for hoisting objects or people during helicopter flight. Using a rear crew helicopter VR training simulator we sought to quantify hoist operator performance and validate this system by showing that experienced SAR hoist operators and novices hoist differently. We recruited 12 military SARs and 11 persons without hoisting experience and examined their performance in moderate wind conditions over two landscapes, ocean and land. Experienced operators were not affected by environment, completed missions faster than novices, made fewer velocity adjustments, and demonstrated better cable management. These variables can now be used as sources of feedback to train novice hoist operators. Since there were differences between performances of experienced and novice hoist operators we have established construct validity of the simulator.

摘要

与飞行员模拟培训的可用性相比，直升机搜索和救援 (SAR) 起重机操作员的虚拟现实 (VR) 模拟培训非常少见。SAR 提升机操作员控制绞盘系统，用于在直升机飞行期间提升物体或人员。使用后方机组直升机 VR 培训模拟器，我们试图量化提升机操作员的表现，并通过展示经验丰富的 SAR 提升机操作员和新手不同的提升来验证该系统。我们招募了 12 名军事 SAR 人员和 11 名没有吊装经验的人员，并在海洋和陆地两个景观中检查了他们在中等风条件下的表现。经验丰富的操作员不受环境影响，比新手更快地完成任务，进行的速度调整更少，并展示了更好的电缆管理。这些变量现在可以用作培训新手起重机操作员的反馈来源。由于经验丰富的起重机操作员和新手起重机操作员的表现之间存在差异，我们已经建立了模拟器的构造有效性。
