Pilot-aircraft haptic feedback tests

Abstract

Purpose The purpose of this study is to lead to an improvement in pilot-aircraft interaction. The goal of the performed tests is an assessment of haptic feedback, which mediates flight parameters to the pilot. Pedals indicate side-slip angle by vibrations, whereas a sliding element inside the control stick is able to continuously indicate both angles of attack and side-slip. Design/methodology/approach Haptic feedback applied on rudder pedals and control stick were tested on a flight simulator and flight tests in a couple of tasks. Pilot workload, readability of feedback and side-slip were then evaluated when the flight was turning. Findings As a useful instrument for aircraft control, haptic feedback was assessed. The feedback settings were then individually perceived, and haptic feedback slightly improved side-slip while turning in a flight test; however, the results are not statistically significant. Practical implications The tests provided promising results for human pilot performance. The training phase and personal settings of haptic feedback is an approach for improving the performance of human pilots. Originality/value The designed and tested device is a unique tool for improving pilot-aircraft interaction. This study brings valuable experiences from its flight simulator and in-flight tests.

Parameters design for feel system of aircraft active inceptor controller

“…This exceeded the maximum control force that pilots could provide. The development and application of the fly-by-wire technology provided a solution to this issue [4][5][6] . Subsequently, the control stick and the control surface were no longer directly connected by mechanical structures [7] .…”

Flying by Feeling: Communicating Flight Envelope Protection through Haptic Feedback

“…Another example uses the active control device to show a set of predicted controllability limits, which was shown to be used by pilots in an experiment (Stepanyan et al, 2017). The relative distance of the aircraft state to the limits can also be presented using vibrations on the pedals and a sliding element on the stick and the evaluation showed promising, positive results (Zikmund et al, 2020).…”
