Passenger aircraft structural design is based on a safety factor of 1.5, and this safety factor alone is equivalent to a probability of failure of between 10 and 10. Yet airliners are much safer, with crashes due to structural failure being extremely rare based on accident records. The probability of structural failure of transport aircraft is of the order of 10 per flight segment. This paper l...

This paper discusses the use of an artificial intelligent paradigm consisting of three intelligent autonomous agents whose purpose is to monitor the flight crew and the aircraft. Two of these agents will monitor the path of the aircraft, one armed with prior knowledge of how planes tend to land at a particular airport, the other with the ability to extrapolate forward from the plane’s current p...

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

Blood samples from aircraft accident victims are analyzed for carboxyhemoglobin (COHb) and cyanide ion (CN(-)). Such victims often suffer open wounds near the autopsy blood collection sites. Many aircraft crashes result in fires that fill the victim's atmosphere with smoke that is rich in carbon monoxide (CO) and hydrogen cyanide (HCN). It is important to determine whether pooled blood in those...

INTRODUCTION This paper aims to provide insights into human perception, navigation performance, and confidence in helicopter overland navigation. Helicopter overland navigation is a challenging mission area because it is a complex cognitive task, and failing to recognize when the aircraft is off-course can lead to operational failures and mishaps. METHODS A human-in-the-loop experiment to inv...

BACKGROUND In the late 1980's, an Army Apache helicopter crashed during a training mission, resulting in fatal injuries to the rear seat pilot and survivable injuries to the front seat copilot. U.S. Army investigators assessed the aircraft damage and aircrew injuries, and examined the helmets, restraint systems, and crashworthy seats. HYPOTHESIS Computer simulations that approximate an actual...

Conflict detection is the process by which potential collisions between aircraft are identified. Developing efficient detection methods is an engineering priority since the prevention of a mid-air collision is a major safety constraint for all airspace design. Proximity between two aircraft each flying with instantaneous uniform straight motion is re-examined. The Apollonius theorem for constru...

A health management (HM) system is responsible for information gathering about a system’s health and corresponding decision-making. HM systems are typically used to identify any degradation in performance that may affect safety or successful operations of a system. Effective long term development of successful health management solutions requires an improved understanding of the relationship be...

To the best of the author’s knowledge, this is one of the first times that a large quantity of flight data has been studied in order to improve safety. A two phase novelty detection approach to locating abnormalities in the descent phase of aircraft flight data is presented. It has the ability to model normal time series data by analysing snapshots at chosen heights in the descent, weight indiv...
