Development of new and innovative applications for high precision differential global positioning systems (DGPS) has exploded in the last two years. Real-time three-dimensional accuracy’s of under three centimeters and processed position update rates in excess of four hertz, along with position update latencies of under eighty milliseconds are now commercially available. Immediate position info...

BACKGROUND Increases in stored iron and dietary intake of iron during space flight have raised concern about the risk of excess iron and oxidative damage, particularly in bone. OBJECTIVES The objectives of this study were to perform a comprehensive assessment of iron status in men and women before, during, and after long-duration space flight and to quantify the association of iron status wit...

During a flight, changes occur in the human body, whose possible reactions can influence well-being and quality of health medicine users, subject scarce studies. The aim this paper is to analyze impacts effects medication use during air transport. Through literature review documentary research methodology, relevant facts about precautions that should be taken regarding flights were considered. ...

In this paper we present a novel approach addressing airline delays and recovery. Airline schedule recovery involves making decisions during operations to minimize additional operating costs while getting back on schedule as quickly as possible. The mechanisms used include aircraft swaps, flight cancelations, crew swaps, reserve crews and passenger rebookings. In this context, we introduce anot...

The 4 payload crew members of the Spacelab Life Sciences 9-day space flight in 1991 were subjected to limited vestibular testing in flight as well as pre and post flight. Major differences in individual "perceptual style" appeared in their reaction to the visual-vestibular stimuli in the rotating dome experiment, and especially in the extent to which nondirectional tactile cues served to anchor...

INTRODUCTION This study examined pilots' visual scan patterns during a simulated high-speed, low-level flight and how their scan rates related to flight performance. As helicopters become faster and more agile, pilots are expected to navigate at low altitudes while traveling at high speeds. A pilot's ability to interpret information from a combination of visual sources determines not only missi...

A comprehensive study of general and special subjects administrative offenses in air transport has been conducted. The range on established. types responsibility for aviation have determined related to violation flights, norms normative legal acts regulating activity investigated.
 It proved that only individuals can be liability, both entities liability the form economic, financial, penal...

In the 20th century air transport has developed into a safe, reliable and economic means of transportation for passengers, cargo and mail. In the next two decades, the air transport is forecasted to double. To enable this expansion to occur within the limited airspace, with the limited number of airports and runways and with the increasing requirements with respect to safety, noise and emission...
