Measurements of air humidity, temperature, carbon dioxide (CO2), respirable particles, ozone, nitrogen dioxide (NO2), formaldehyde, and volatile organic compounds of possible microbial origin (MVOC) were performed during 26 flights with Boeing 767-300. The mean temperature in cabin was 22.2 °C (range 17.4-26.8 °C), and mean relative air humidity was 6% (range 1-27%). The CO2 during cruises was ...

UNLABELLED Passengers in an aircraft cabin can have different risks of infection from airborne infectious diseases such as influenza, severe acute respiratory syndrome (SARS), and tuberculosis (TB) because of the non-uniform airflow in an aircraft cabin. The current investigation presents a comprehensive approach to assessing the spatial and temporal distributions of airborne infection risk in ...

The International Commission on Radiological Protection (ICRP) had in 1990 recommended that civilian aircrew be classified as being occupationally exposed to low-dose ionizing radiation, in view of their increased exposure to cosmic rays at altitude. In 2000, the European Union had gone ahead with legislation which requires all European airlines to monitor cosmic radiation levels during flight ...

We consider the control problem of a Variable Configuration CO2 Removal system, which exhibits a hybrid dynamical character due to various operating modes of the system. The objective of the control problem is to track a desired concentration profile of CO2 and O2 in a crew cabin while keeping their concentrations within permissible bounds. We present a novel adaptation of the model predictive ...

The Human Powered Centrifuge (HPC) is a facility that is planned to be installed on board the International Space Station (ISS) to enable crew exercises under the artificial gravity conditions. The HPC equipment includes a “bicycle” for long-term exercises of a crewmember that provides power for rotation of HPC at a speed of 30 rpm. The crewmember exercising vigorously on the centrifuge generat...

The current study aims to explore the intrinsic and extrinsic motivators for cabin crew members’ ambidexterity investigate influence of on prosocial service behavior. authors employed PLS-SEM examine model, using 428 valid samples from members, their pursers, managers working airlines in South Korea. found that challenge, empowerment, learning goal orientation, among four dimensions motivators,...
