Abstract. Compared with other team settings, flight crew in air transport present a unique situation where the leader or supervisor regularly engages in active control. When the captain is assigned cognitively demanding pilot flying duties, the subordinate and often less experienced first officer must perform equally crucial monitoring and support duties. Using a systematic review methodology, this study reviews the reported effect of crew role assignment on flight safety outcomes. Our review identified 18 relevant studies and suggests crew performance factors linked to flight safety are affected by crew role assignment. Findings suggest a greater number of inherent obstacles may exist for optimal crew performance with the captain as pilot flying, raising the need for further specific research and policy review in this area.

Manned Space Flights

Since April 1961, all manned space flights have been accompanied by medical control ensuring flight safety. Medical control in space flight has a technological and medical methodology that allows, at a distance from medical specialists, to make an adequate medical decision for the current situation. This work would be impossible if there were no measures taken to unify and standardize equipment and techniques. Telemedicine technologies developed on the basis of flight medical control. The origin of the word telemedicine comes from the expression «telemetric medical information», adopted in space technology. The issues of mutual development and mutual enrichment, standardization of methods and equipment of two areas of medicine, medical control in extreme situations and general telemedicine are considered in this article.

Hypoxia remains a flight-safety issue in terms of aviation medicine. Hypoxia-awareness training has been used to help aircrew members recognize personal hypoxia symptoms. There is still no study, as yet, to establish the association of within-subject data between inflight hypoxia events and the altitude chamber. The main purpose of our study was to use paired subjects’ data on inflight hypoxia symptoms compared with those experienced during training. A questionnaire was developed to obtain information on military aircrew members in 2018. Among 341 subjects, 46 (13.49%) suffered from inflight hypoxia. The majority of the subjects detected ongoing inflight hypoxia on the basis of their previous experience with personal hypoxia symptoms or sensations in previous chamber flights. Of the top five hypoxia symptoms, the data revealed that hot flashes, poor concentration, and impaired cognitive function appeared both during the inflight events and during the hypoxia-awareness training. The occurrence rate of hypoxia symptoms was found to not be significantly different between the in-flight events and the past chamber flights through an analysis of within-subject data. Because the individual memory had faded away over time, fresher hypoxia awareness training is still mandatory and valuable to recall personal hypoxia experience for military aircrew members.

In modern aircraft, energy supply management has become a critical matter, since many aboard electrical loads have to be supplied, especially those related to flight safety. However, at the same time, the size and weight of electrical generators must be limited because of their on-board installation. In this paper, the Mixed Integrated Linear Programming (MILP) methodology has been used to formulate the Supervisor definition of the direct current (DC) microgrid (MG) on-board system with an extension for the programmable loads. Due to the problem of dimension increase, two methods have been presented and tested to perform optimal energy management (EM) aboard an aircraft: the Branch and Bound (B&B) and the Linear Regression Approximation (LRA). Finally, numerical simulations and results have been provided to validate the proposed optimization methodologies, according to the dimensions and the complexity of the problem.

In order to ensure flight safety and efficiently sequence departure aircraft in airspace class D, a sequencing model for scheduling the sequence of departure aircraft in airspace class D was discussed. Model's objective is minimizing the loss of delays under the premise separation minima which is used to keep the safety between proceeding aircraft and following aircraft must be satisfied. Then the model is transferred to pure integer nonlinear program model so that it can be solved by some program software like Lingo. At last, a numerical example is used to illustrate the process of solving the model. The numerical example shows that the model proposed in this paper is extremely efficient and model used for the aircraft sequencing in the airspace class D is feasible.
