Flight Performance Aspects During Military Helicopter Flights
Aerospace Medicine and Human Performance, 2019 INTRODUCTION: A flight is composed of many flight performance aspects. However, not all of these aspects are equally important for the success and safety of a flight. When investigating the influence of a stressor on flight performance, it is important to understand not only which flight performance aspects are important for the success and the safety

Extraordinary flight performance of the smallest beetles. [PDF]
Proc Natl Acad Sci U S A, 2020 Size is a key to locomotion. In insects, miniaturization leads to fundamental changes in wing structure and kinematics, making the study of flight in the smallest species important for basic biology and physics, and, potentially, for applied disciplines.

Enhanced flight performance in hoverfly migrants. [PDF]
iScienceMany animals undergo seasonal migrations in which they travel long distances aided by variations in morphology, physiology, and behavior. Here, we compare the flight characteristics, measured in a tethered flight mill, of autumn migratory and summer non-migratory morphs of the marmalade hoverfly Episyrphus balteatus (Diptera: Syrphidae), an ...

Flight muscle breakdown in the green-veined white butterfly, Pieris napi (Lepidoptera: Pieridae)
European Journal of Entomology, 2008 Flight is important for insects but also incurs costs in terms of reduced reproductive reserves. Recent studies on butterflies have shown that thorax mass and nitrogen content decrease over the adult lifespan, suggesting that flight muscle breakdown may ...

Insects, 2022 Here we aimed to assess whether variation in (1) developmental temperature and (2) transport conditions influenced the low-temperature performance and flight ability of false codling moth (FCM) adults in an SIT programme. To achieve the first aim, larvae

New methods for estimating the total wing area of birds
Ecology and Evolution, 2023 Dispersal is a fundamental process in evolution and ecology. Due to the predominant role of flight in bird movement, their dispersal capabilities can be estimated from their flight morphology.

European Journal of Entomology, 2019 Movements are involved in several routine processes and may scale up to important ecological processes such as dispersal. However, movement is affected by a wealth of factors including flight capacity and behavioural traits. Both frequently differ in the
