The project “Human Performance Envelope” builds on a concept previously proposed in the ATM domain. It aims at defining and applying the Human Performance Envelope for cockpit operations and at identifying methods to measure the crew’s performance and to recover it to the centre of the envelope through improved Human Machine Interface design and operational procedures.
The Human Performance Envelope is to some extent a new paradigm in Human Factors. Rather than focusing on one or two individual factors (e.g. fatigue, situation awareness, etc.), it considers a range of common factors in accidents and maps how they work alone or in combination to lead to a performance decrement that could affect safety. The safe region of the envelope is bordered by markers which can be measured and signalled allowing the pilots to detect and recover, or enabling external agencies to prompt recovery, or allowing automation to kick in and take over. The Human Performance Envelope will deal with the most crucial people in the accident chain, giving them back-up when they most need it, assuring performance when things get difficult. It will increase safety by focusing on the sharp end of accidents.
The impact of the “Human Performance Envelope” Project will primarily be through the improved design and operational practices in the cockpit. The ultimate objective is to augment the Human Performance Envelope through Human Machine Interface (HMI) principles, innovative HMI design, automation concepts and flight crew monitoring solutions (with impact on procedures or training). Simulator experiments with pilots will be conducted to measure the different factors of the Human Performance Envelope, to identify performance decrements, and subsequently to establish the boundaries of the Envelope. On this basis new HMIs will be developed that help the pilots to recover when one or several factors are degraded and thereby to remain inside the boundaries of the Human Performance Envelope. The new HMIs will be validated in further flight simulator experiments with pilots.
