ABSTRACT

Objective

This study investigates the relationship of pilot inceptor workload (PIW) with the workload buildup flight test technique (WBFTT) with various conditions of pilot workload, for objective aircraft handling qualities (HQ) evaluation.

Background

HQ evaluation of a piloted aircraft remains an elusive area of flight testing, due to the existing subjective evaluation technique for the pilot workload. The pilot control inceptor being an important interface for a pilot with the aircraft, it is the best tool to estimate pilot workload.

Method

The statistical model of this research involved 3 independent variables, namely aircraft flying qualities, secondary task, and boundary effect of WBFTT, each differently affecting the pilot workload. Two studies were undertaken on a fixed-base, variable-stability HQ research flight simulator with military test pilots. In-flight study of pilot inceptor movement was undertaken in an advanced jet trainer aircraft during high pilot-gain air-to-ground target tracking tasks.

Results

The results of simulator studies validated the relationships of PIW and WBFTT with statistical significance from a wide set of data, with variations in pilot workload in terms of flying qualities and secondary task. The in-flight studies validated the effects of high pilot gain and proximity to ground (boundary), on the pilot inceptor movements, in training combat maneuvers.

Conclusion

Studies manifested PIW as a simple and direct measure to estimate pilot workload and WBFTT as an effective technique for HQ stress testing with high pilot gain.

通过模拟器和飞行研究研究飞行员接收器工作量和工作量积累技术

摘要

客观的

本研究调查了飞行员接收器工作量 (PIW) 与工作量累积飞行测试技术 (WBFTT) 与飞行员工作量的各种条件之间的关系，用于客观的飞机操纵质量 (HQ) 评估。

背景

由于现有的飞行员工作量主观评估技术，驾驶飞机的总部评估仍然是飞行测试中难以捉摸的领域。飞行员控制接收器是飞行员与飞机的重要接口，是估计飞行员工作量的最佳工具。

方法

本研究的统计模型涉及 3 个自变量，即飞机飞行质量、次要任务和 WBFTT 的边界效应，每个变量对飞行员的工作量都有不同的影响。两项研究是在一个固定基地、可变稳定性 HQ 研究飞行模拟器上与军事试飞员一起进行的。在高飞行员增益空对地目标跟踪任务期间，在先进的喷气教练机上进行了飞行员接收器运动的飞行研究。

结果

模拟器研究的结果验证了 PIW 和 WBFTT 的关系，从广泛的数据集具有统计意义，在飞行质量和次要任务方面飞行员工作量的变化。飞行中的研究验证了高飞行员增益和接近地面（边界）对飞行员接收器运动和训练战斗演习的影响。

结论

研究表明，PIW 是一种简单直接的方法来估计飞行员的工作量，而 WBFTT 是一种有效的 HQ 压力测试技术，具有高飞行员增益。
