Task Management (TM) refers to the function in which the human operator manages his/her available sensory and mental resources in a dynamic, complex, safety critical environment in order to accomplish the multiple tasks competing for a limited quantity of attention. There is reason to believe that the level of automation on the commercial aircraft flight deck may affect TM. Two samples of 210 A...

OBJECTIVE For more than three decades, women at imminent risk of preterm birth (PTB) in Western Australia have been transferred by small aircraft over long distances to the single tertiary level perinatal centre in Perth, with no known case of birth during the flight. We aimed to review recent experience to understand how aircraft travel may delay PTB. DESIGN AND SETTING Retrospective observa...

As air traffic congestion grows, ground-holding (or "gate-holding") of aircraft is becoming increasingly common. Ground-holding is the practice of delaying the departure of a flight due to anticipated congestion at the airport of destination, because it is both less expensive and safer, for aircraft to wait on the ground, prior to take-off, than in the air. The problem of developing strategies ...

The paired approach procedure is intended to facilitate IFR approaches to closely spaced parallel runways (closer than 2500 feet) and increase runway throughput where parallel ILS approaches cannot be conducted under instrument meteorological conditions. The paired approach procedure requires that air traffic control pair compatible and eligible aircraft and place them on the final approach cou...

This document describes a closed-loop aircraft model for testing the performance of Flight-deck Interval Management (FIM) avionics. The derivation of a point-mass aircraft model with and without winds is presented. Guidance control laws used to track a four-dimensional trajectory, described as a reference horizontal path, a vertical profile, and an indicated airspeed command, are also presented...

Abstract This paper expounds the method of determining civil aircraft brake energy scenario. Brake is an extremely important requirement for carbon disc and fusible plug design system. In order to determine kinetic capacity, following conditions should be considered: designed landing-stop condition, normal landing stop reject takeoff condition most severe condition. As related operational envir...

Manually landing an unmanned aerial vehicle presents unique challenges since unmanned vehicle pilots require extensive training to become proficient in the landing task. Operators must therefore choose between a pilot controlling the vehicle from a ground station, or procurement of an automatic landing system. Although several autoland controllers exist for small or micro unmanned vehicles and ...
