Expert system applications must be carefully selected, designed and integrated into the cockpit based on a full understanding of the pilot's tasks, requirements, and capabilities. In this paper, expert systems development issues in the following areas are identified and addressed utilizing processes, methodologies and knowledge from the human factors field: the selection of systems to automate, the elicitation of expert knowledge from pilots, role allocation between the pilot and the system, system design issues, and system evaluation. Considerations of pilot workload, situational awareness, performance and pilot acceptance are considered key to the successful design and implementation of expert systems which will truly enhance the pilot in the performance of his tasks.

Vertical Lift

The United States Army is developing and procuring their next generation of rotorcraft, called the Future Vertical Lift (FVL) program. FVL rotorcraft will fly faster and incorporate new work requirements such as command of unmanned systems and optionally piloted variants. Successful design and implementation of human automation teaming will be paramount to the mission success and safety of FVL systems, presenting both challenges and opportunities for human factors personnel supporting FVL development. The purpose of this panel is to highlight the range of human factors challenges within the FVL program. Panelists are drawn from both government and industry, and represent a diverse set of perspectives including user, researcher, and practitioner. The session will include time for panelists to introduce their work and challenges that they are addressing within the FVL program as well as interact with audience members.

Human Factors Analysis

On December 14, 1799, 3 prominent physicians—Craik, Brown, and Dick—gathered to examine America’s first president, George Washington. He was complaining of severe throat symptoms and was being treated with bloodletting, blistering, and enemas. Dick advised performing an immediate tracheotomy to secure the airway. Both Craik and Brown were not keen on trying tracheotomy and overruled that proposal. Washington was not involved in making that decision. He most likely had acute epiglottitis that proved to be fatal at the end. If Dick had prevailed, a tracheotomy could have saved Washington’s life. Human factors analysis of these events shows that his physicians were totally fixated on repeating futile treatments and could not comprehend the need for a radical alternative, like tracheotomy. That was aggravated by an impaired situational awareness and significant resistance to change. Leadership model was also based on hierarchy instead of competency, which might have also contributed to Washington’s death.

Controlled crop growth parameters, such as average air velocity, air temperature, and relative humidity (RH), inside the greenhouse are necessary prerequisites for commercial greenhouse operation. Frequent overshoots of such parameters are noticed in the Middle East. Traditional heating ventilation and air-conditioning (HVAC) systems in such greenhouses use axial fans and evaporative cooling pads to control the temperature. Such systems fail to respond to the extreme heat load variations during the day. In this study, we present the design and implementation of a single span, commercial greenhouse using box type evaporative coolers (BTEC) as the backbone of the HVAC system. The HVAC system is run by a fully-automated real time feedback-based climate management system (CMS). A full-scale, steady state computational fluid dynamics (CFD) simulation of the greenhouse is carried out assuming peak summer outdoor conditions. A pilot study is conducted to experimentally monitor the environmental parameters in the greenhouse over a 20-h period. The recorded data confirm that the crop growth parameters lie within their required ranges, indicating a successful design and implementation phase of the commercial greenhouse on a pilot scale.

Abstract Introduction In the already high-risk, high-stress environment of the operating theatre, operating during Covid-19 has brought its own unique challenges. Communication, teamwork and anxiety related new operating practices secondary to Covid-19 are hypothesised to have a negative impact on patient care. Method We conducted a single-centre online survey of operating theatre staff from 22nd June–6th July 2020. Respondents completed 18 human factors questions related to COVID-19 precautions including communication, teamwork, situational awareness, decision making, stress, fatigue, work environment and organisational culture. Questions consisted of yes/no responses, multiple choice and Likert items. Kruskall-Wallis tests, Chi-Squared, Mann Whitney U tests, Spearman’s correlation coefficient, lambda and Cramer’s V tests were used. Free-text responses were also reviewed. Results 116 theatre staff responded. Visual (90.5%), hearing/ understanding (96.6%) difficulties, feeling faint/lightheaded (66.4%) and stress (47.8%) were reported. Decreased situational awareness was reported by 71.5% and correlated with visors (r = 0.27 and p = 0.03) and FFP2/3 mask usage (r = 0.29 and p = 0.01). Reduced efficiency of theatre teams was reported by 75% of respondents and 21.5% felt patient safety was at greater risk due to Covid-19 precautions in theatre. Conclusions Organisational adjustments are required, and research focused on development of fit-for-purpose personal protective equipment (PPE).

Abstract Introduction During Covid-19 many staff members were redeployed to the Intensive Care Unit (ICU) with little opportunity to train in the new skills they would require. One such skill was the transfer of a critically ill, and contagious, patient from ICU; a risky and complicated procedure which requires planning, preparation, risk assessment, situational awareness and, ideally, experience. To assist our colleagues in this skill an existing ICU transfer course has been adapted to cover the Covid-19 situation, or any similar contagious pandemic, in patient transfer. Methods An in-situ simulation method was chosen as the most realistic method of immersing our participants into the environment of ICU and to highlight real-life complexities and issues they may face. A multidisciplinary training session was devised so that novice anaesthetists, ACCPs and nurses could learn together, reflective of the usual team. Human factors such as communication, team leadership, task management and situational awareness are the focus of the post-simulation debrief, and human factors sheets have been created to guide the participants in analysing these skills. Pre- and post-simulation confidence, knowledge and attitudes will be assessed using validated appraisal tools and questionnaires to gather both quantitative and qualitative data about the experience. Discussion Multidisciplinary training is often difficult to arrange, due to the different requirements, processes, and procedures each department demands. A hidden blessing of Covid-19 is the realisation that this barrier can be broken, for the benefit of our patients and colleagues alike, and training sessions like this implemented.

Current demands on prototyping emphasize increasingly complex and dynamic applications that require sophisticated social mechanism and process enablers. However, much of the emphasis placed today in systems development under prototyping focuses on the supporting technology. The imbalance between product and process perspectives under this approach is explored. A view of prototyping effectiveness is presented in terms of non-linear problem solving, adequate technical and procedural solutions, and organizational support. Implications of this view are presented on the selection of prototyping techniques and on project management concerns. Future developments in prototyping practice are explored.
