The purpose of the current research was to investigate whether performance in nonradar training would predict performance in radar training.
There is a discussion in the Federal Aviation Administration about the necessity of keeping nonradar training as part of the required selection criteria for radar controllers. In nonradar training, controllers separate traffic by relying on the estimated time over navigational fixes printed on flight progress strips, rather than monitoring the perceptually available positional information on a radar screen. The two ways of controlling traffic-nonradar and radar-are different along a number of dimensions.
Sixteen participants were taught to control simulated air traffic using nonradar and radar procedures. Performance on final radar scenarios was predicted from cognitive variables; performance on earlier, simpler radar scenarios; and performance on nonradar scenarios.
Performance during nonradar trials predicted final radar performance (i.e., collisions and landed aircraft count) independent of the predictive power of cognitive variables and above and beyond earlier radar training.
Performance in nonradar training enhanced users' ability to predict radar performance, even in addition to the predictive power of simpler, earlier radar performance variables. Good nonradar performers had higher situation awareness in the radar environment.
Performance in a nonradar environment may serve as an important selection tool in assessing the performance of student controllers in radar environments. The results indicate the need for future research with field controllers.
当前研究的目的是调查非雷达训练中的表现是否能预测雷达训练中的表现。
美国联邦航空管理局正在讨论将非雷达训练作为雷达管制员所需选拔标准一部分的必要性。在非雷达训练中,管制员依靠印在飞行进程单上的预计飞越导航定位点的时间来分隔交通,而不是在雷达屏幕上监测可感知的位置信息。非雷达和雷达这两种控制交通的方式在多个方面存在差异。
16名参与者学习使用非雷达和雷达程序控制模拟空中交通。根据认知变量、早期较简单雷达场景的表现以及非雷达场景的表现来预测最终雷达场景的表现。
非雷达试验期间的表现独立于认知变量的预测能力以及早期雷达训练,预测了最终雷达表现(即碰撞和着陆飞机数量)。
非雷达训练中的表现增强了用户预测雷达表现的能力,即使除了更简单、更早的雷达表现变量的预测能力之外。非雷达表现出色的人员在雷达环境中具有更高的态势感知能力。
非雷达环境中的表现可能作为评估学员管制员在雷达环境中表现的重要选拔工具。结果表明未来需要对现场管制员进行研究。
