In-flight transmission of foodborne disease: How can airlines improve?

Recent progress on quality improvement and detection technologies of special foods used for activities in space and aviation: a review

This paper focuses on the development and evolution, quality improvement and research progress in the rapidly emerging area of new detection technologies of special foods for use in space and to some extent aviation. The quality improvement aspects covered in this review ranged from the special food processing technology, sterilization treatment and product packaging to new detection technologies for quality assurance based on DNA microarray technology, sensor, imaging technology, carbon nanotubes and novel probe technology.

Cabin crew health and fitness-to-fly: Opportunities for re-evaluation amid COVID-19

Aircrew fitness-to-fly is among the elements that make aviation the safest form of long-distance transport. The health of cabin crew is a crucial determinant in carrying out safety-related duties. 'Fitness-to-fly' is associated with defined workplace conditions, for which airlines have a legal duty to ensure fitness for employment. We explored the literature on fitness-to-fly to obtain a pragmatic assessment of the challenges for aeromedical examinations. Regulations promulgated by aviation regulatory authorities and airline-internal policies have similar status and meaning, yet there is no harmonised approach internationally, and an inability to conform periodic medical assessments to actual operational fitness. The COVID-19 pandemic has highlighted the need to better understand fitness-to-fly criteria. Fitness-to-fly measures are mainly based on self-reported data and there is a need for a 'safety' factor for self-reports. Aeromedical evaluations should evolve from meeting medical standards to include pandemics as an element of the overall risk of aircraft operations. Re-evaluating criteria for fitness-to-fly assessment will further the goal of linking research to the actual needs of public health decisionmakers. If airlines are to resume operations at pre-pandemic levels, they must demonstrate to the public and public health agencies that fitness-to-fly assessment is appropriate and effective.

Ultra Long-Haul: An emerging business model accelerated by COVID-19

The COVID-19 outbreak has sent shockwaves throughout the aviation industry, sending a myriad of liquidity-strapped airlines into administration or part government ownership. In turn, this paper argues that the novel phenomenon of Ultra Long Haul (ULH) operations already maintains the necessary characteristics to generate a competitive advantage that will not only succeed, but outperform other business models, in a post COVID-19 era. Our modelling and scenario analysis results suggest that point-to-point ULH services, with access to a strong domestic feeder system, will not only require minimal adjustments to cope with COVID-19, but will simultaneously produce higher seat-load factors and yields, heightened network flexibility, and unique health benefits tied to its ability to bypass densely populated hub airports.
