The dynamics of parabolic flight: Flight characteristics and passenger percepts [PDF]
Acta Astronautica, 2008 Flying a parabolic trajectory in an aircraft is one of the few ways to create freefall on Earth, which is important for astronaut training and scientific research. Here we review the physics underlying parabolic flight, explain the resulting flight dynamics, and describe several counterintuitive findings, which we corroborate using experimental data ...

Perception of Egocentric Distance during Gravitational Changes in Parabolic Flight. [PDF]
PLoS ONE, 2016 We explored the effect of gravity on the perceived representation of the absolute distance of objects to the observers within the range from 1.5-6 m. Experiments were performed on board the CNES Airbus Zero-G during parabolic flights eliciting repeated ...

Perception of Affordance during Short-Term Exposure to Weightlessness in Parabolic Flight. [PDF]
PLoS ONE, 2016 We investigated the role of the visual eye-height (VEH) in the perception of affordance during short-term exposure to weightlessness. Sixteen participants were tested during parabolic flight (0g) and on the ground (1g).
