Abstract
A programme of work is being undertaken with the aim of defining features to help the pilot respect the helicopter's numerous flight limitations, reducing the workload and enhancing mission performance.
Carefree handling features that have been studied include visual, audible and tactile cues and direct intervention methods. These features have been evaluated in a series of piloted simulation trials at DRA Bedford. Most of the work to date has been based around helicopters with active control technology (ACT) flight control systems, but conventionally controlled helicopters have also been considered.
Results from the programme suggest some benefits for head-up visual displays, tactile and audible cues, with more significant benefits for the direct intervention methods. A combination of these features allows the pilot to use the full performance of the vehicle without exceeding limits and at low pilot workload.
