Managing operations of the aircraft approach process and analyzing runway landing capacity, utilization and related risks require detailed insight into the stochastic characteristics of the process. These characteristics can be represented by probability distributions. The focus of this study is analyzing landings on a runway operating independent of other runways making it as a single runway. ...

The primary aim of this study was to examine the role of cue utilization in the initial acquisition of psycho-motor skills. Two experiments were undertaken, the first of which examined the relationship between cue utilization typologies and levels of accuracy following four simulated, power-off landing trials in a light aircraft simulator. The results indicated that higher levels of cue utiliza...

Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...

BACKGROUND & OBJECTIVES Anopheles minimus and An. fluviatilis were incriminated as the major malaria vectors in Keonjhar district of Odisha State recently. This study was carried out to elucidate the potential role of these two vector species in transmission of malaria during different seasons, and vectorial capacity of these species was also estimated. METHODS Three hilly and forested villag...

We describe our work on multirotor UAVs and focus on our method for autonomous landing. The paper describes the design of our landing pad and its advantages. We explain how the landing pad detection algorithm works and how the 3D-position of the UAV relative to the landing pad is calculated. Practical experiments prove the quality of these estimations.

A three-dimensional phenomenological model was developed to describe the collective landing of bird flocks. The employed individual based model included the landscape (as an external field) and a continuous internal variable G, to characterize the landing intent of the birds. The birds' interaction with the landscape was coupled adaptively to their landing intent. During the flight, a sharp cro...

Hazard Avoidance is a key technology for a safe landing of future planetary missions. During Hazard Avoidance, sensors and computers onboard the lander are used to detect hazards in the landing zone, autonomously select the most suitable region for landing, and generate the trajectory that retargets the lander to the safer landing site. In this paper, visionbased hazard avoidance algorithms are...

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 ...
