An aircraft is said to be operated in a trim condition when the body axis accelerations are zero. In other words, no resultant forces or torque act on the aircraft. The purpose of the longitudinal controller of an aircraft is to help pilots to move the aircraft from one trim condition to another, or to stabilize the aircraft in an operating trim condition while the aircraft is subjected to dist...

It is of great significance to identify and clarify the circumstances and causes of any aircraft accident which will help avoid similar accidents in the future. Besides attribution of various aircraft accidents to avionic causes, bad weather is another prime cause for accidents of many aircraft and helicopters in India. But hardly any study is available in this regard in India using their longp...

In military operations, logistics distribution involves the transportation of equipment, people and sustainment (resources) to various physical locations, known as distribution nodes. The quantity of items being transported is often very large and the resources need to be moved as quickly as possible using the available transportation assets. A complicating factor is that the airports at the di...

CONTEXT Installation of automated external defibrillators (AEDs) on passenger aircraft has been shown to improve survival of cardiac arrest in that setting, but the cost-effectiveness of such measures has not been proven. OBJECTIVE To examine the costs and effectiveness of several different options for AED deployment in the US commercial air transportation system. DESIGN, SETTING, AND SUBJE...

FAA’s NextGen program aims to increase the capacity of the national airspace, while ensuring the safety of aircraft. This paper provides a distributed merging and spacing algorithm that maximizes the throughput at the terminal phase of flight, using information communicated between neighboring aircraft through the ADS-B framework. Aircraft belonging to a mixed fleet negotiate with each other an...

This paper presents a short contribution in air transportation, specifically in scheduling aircraft (plane) landings at Léopol Sédar Senghor (LSS) airport of Dakar. The safety of air navigation of LSS is managed by ASECNA: Agency for Air Navigation Safety in Africa and Madagascar. Scheduling aircraft landing is the problem of deciding a landing time on an appropriate runway for each aircraft in...

This paper presents hybrid integration between aerodynamic, airline procedures and other BADA-based (Base of Aircraft Data) coefficients with a classical aircraft dynamic model. This paper also describes a three-dimensional guidance algorithm implemented in order to produce commands for the aircraft to follow a flight plan. The software chosen for this work is MATLAB. Key words— UAS, aircraft, ...

We study a dynamic repair shop scheduling problem in the context of military aircraft fleet management. A number of flights, each with a requirement for a specific number and type of aircraft, are already scheduled over a long horizon. The overall scheduling horizon is considered to be composed of multiple time periods. The goal is to maintain a full complement of aircraft. We need to assign ai...

Aerodynamicists and biologists have long recognized the benefits of formation flight. When birds or aircraft fly in the upwash region of the vortex generated by leaders in a formation, induced drag is reduced for the trail bird or aircraft, and efficiency improves. The major consequence of this is that fuel consumption can be greatly reduced. When two aircraft are separated by a large enough lo...

This paper has maintained review and conclusion work upon the research and state of development of Man-Machine-Environment System Engineering (MMESE) technology applied in the aircraft design domain of China. The research development discussed involves: Preliminary design of MMESE of aircraft, environment control and Life-support system design of aircraft, and, the environment simulate of aircr...
