In order to enable pilots to better maintain energyawareness and energy management in manual flight, a new concept has beenproposed, which transfers the demand control principle of fly-by-wire controllaws also to the control of thrust. It includes a total-energy-related augmentedthrust controller combined with a modified cockpit instrumentation enriched byspecific energy displays. In order to empirically evaluate the human performanceconsequences of this new approach, an experimental study was conducted in aflight simulator investigating its effects on pilots’ performance,workload, and situation awareness. A total of 24 commercial aircraft pilotsperformed a landing and approach on a complex flight trajectory with and withoutthe new system elements. The results confirm the expected beneficial effects ofthe new system on flight precision and lowered effort involved in thrust controlas compared with conventional raw data flying. No negative side effects, forexample, impaired situation awareness, were found.
