Airline companies use specific selection criteria for cabin crew to ensure that candidates meet their physical requirements. Some of these are the height and reach distance candidates. This criterion is designed so can effectively perform tasks such as being able master emergency equipment, have access upper storage compartments assist disabled or injured passengers. The aim this study examine ...

The authors thank the referee for the constructive and helpful comments. Our detailed replies to the referee 2’s comments (in Italic) are given below. Anonymous Referee 2 This manuscript discusses an important topic, the contribution of ion-induced nucleation on atmospheric new particle formation. It is well-written, and in its current form, discreet, compared to the original manuscript. It is ...

Over the last two decades, troubled airlines were oftenly on news delebrating financial difficulties, layouts distrupted sceduled flights. Covid-19 also impact deterioration of d...

The crew pairing problem is an airline optimization problem where a set of least costly pairings (consecutive flights to be flown by a single crew) that covers every flight in a given flight network is sought. A pairing is defined by using a very complex set of feasibility rules imposed by international and national regulatory agencies, and also by the airline itself. The cost of a pairing is a...

OBJECTIVE To examine an industry funded and controlled study of in flight air quality (IFAQ). METHODS Systematic search of internal tobacco industry documents available on the internet and at the British American Tobacco Guildford Depository. RESULTS Individuals from several tobacco industry companies, led by Philip Morris, designed, funded, conducted, and controlled the presentation of res...

This article explores the development of previous models to determine hubs in a competitive environment. In this paper, by comparing parameters of the ticket price, travel time and the service quality of hub airports, airline hubs are divided into six categories. The degree of importance of travel time and travel cost are determined by a multivariate Lagrange interpolation method, which can pla...

Turbine balancing is an important and regular maintenance operation at airline companies. Because of manufacturing inaccuracies, variations occur in the weights of the blades that can, in turn, lead to significant out-of-balance forces on the engine. The overall time required for balancing can be significantly decreased if the best placement of turbine blades is first determined mathematically....
