A human-in-the-loop (HITL) simulation experiment was conducted by the National Aeronautics and Space Administration (NASA) to assess airline transport pilots’ performance and reported acceptance of the use of procedures relying on airborne separation assistance and trajectory management tools. This study was part of a larger effort involving two NASA centers that includes multiple HITL experime...

Prospective memory is the ability to remember to perform acts in the future. Prospective memory is essential in the aviation domain because it supports a range of tasks including remembering to complete critical radio communications. A wide variety of literature reports that in the laboratory younger adults outperform older adults on many prospective memory tasks. In naturalistic settings howev...

This paper describes an experimental study investigating pilots' manual flying skills. In today's line oriented flight training, basic flying skills are neglected frequently. So, the study examines the manual flying skills of commercial airline pilots under the influence of several performance shaping factors like training, practice or fatigue in a landing scenario. The landing phase shows a di...

INTRODUCTION Previously, we have shown that naïve subjects produce exaggerated isometric forces when exposed to increased acceleration (+Gz) for the first time. The present study investigates whether +G,-experienced PA-200 Tornado pilots show similar deficits. METHODS Experiments were conducted in the stationary (+1 Gz) or rotating (+3 Gz) gondola of a human-rated centrifuge. With their domin...

Ten experienced licensed private pilots were trained for 8 hours on a flight simulator landing task. They each smoked a cigarette containing 19 mg of delta 9-tetrahydrocannabinol (THC), and 24 hours later their mean performance on the flight task showed trends toward impairment on all variables, with significant impairment in number and size of aileron changes, size of elevator changes, distanc...

This paper investigates the interaction effects of motion filter order and break frequency on pilots’ manual control behavior performance using two simulators. Eighteen pilots performed...

This study addresses the problem of pilots receiving ineffective training partly because there is no strategy for incorporating a proper mix of context elements into simulator design. The analysis includes a situated cognition theoretical framework to address the question of determining the influence of motion and visual fidelity on pilot performance in flight simulators. Secondary data on the ...

Background: Expert knowledge may compensate for age-related declines in basic cognitive and sensory-motor abilities in some skill domains. We investigated the influence of age and aviation expertise (indexed by Federal Aviation Administration pilot ratings) on longitudinal flight simulator performance. Methods: Over a 3-year period, 118 general aviation pilots aged 40 to 69 years were tested an...

 ABSTRACT In this paper Artificial Neural Network (ANN) is used for channel estimation in MIMO OFDM systems over AWGN fading channels. Neural Network is trained on the basis of pilots over the different layers using back propagation algorithm. In OFDM system, pilots are used here in order to estimate the channel. Pattern of pilots must be able to match the channel behavior both in time and fre...
