Runway length is usually a critical point in an airport system so, a great interest has been created for optimal use of this runway length. The most important factors in modeling of aircraft landing problem are time and cost while, the costs imposed on the system because of moving away from target times have different performances in terms of impact. In this paper, firstly, aircraft landing pro...

This paper deals with the simulation of landing gear semi-active control for a small trainer aircraft in a multibody framework. The behavior of single passive landing gear drop test simulation models and of a complete aircraft landing simulation model, developed and implemented in the commercial multibody code ADAMS in previous works, is compared to the that of analogous models equipped with se...

Due to an anticipated increase in air traffic during the next decade, air traffic control in busy airports is one of the main challenges confronting the controllers in the near future. Since the runway is often a bottleneck in an airport system, there is a great interest in optimizing the use of the runway. The most important factors in aircraft landing modeling are time and cost. For this reas...

Autonomous contingency management systems, such as a forced landing system which reacts appropriately to an engine failure is important for the safe operation of Unmanned Aircraft Systems (UAS). This paper details a method to ascertain the reachability of any possible emergency landing site for a forced landing in steady uniform wind conditions. With knowledge of the aircraft’s state, such as s...

Title of Document: EMERGENCY FLIGHT PLANNING FOR THE GENERALIZED TRANSPORT MODEL AIRCRAFT WITH LEFT WING DAMAGE Yunshen Tang, Master of Science, 2006 Directed By: Assistant Professor, Ella M. Atkins, Department of Aerospace Engineering A nontrivial fraction of aviation accidents are caused by in-flight damage or failures that reduce performance. Researchers are working to ensure future avionics...

This paper presents an intelligent control scheme that uses a cerebellar model articulation controller (CMAC) and genetic algorithms (GA) in aircraft automatic landing control and to make automatic landing systems (ALS) more intelligent. The proposed intelligent controller can act as an experienced pilot and guide the aircraft to a safe landing in severe turbulence environment. Current flight c...

The atmospheric disturbances affect not only flying qualities of an airplane but also flight safety. According to flight records, most aircraft accidents occurred during final approach or landing. If the flight conditions are beyond the preset envelope, the automatic landing system (ALS) is disabled and the pilot takes over. An inexperienced pilot may not be able to guide the aircraft to a safe...

Landing an aircraft in a remote landing zone autonomously presents several challenges. Firstly, the exact location, orientation, and elevation of the landing zone is not always known; secondly, the accuracy of the aircrafts navigation solution is not always sufficient for this type of precision maneuver. This paper explores a method for estimating the relative position and attitude of the aircr...

This paper provides an overview of literature on visual perception for position and motion awareness in general, and focuses on the visual inputs used by human pilots for landing aircraft in particular. General introductions are given on the background of manual aircraft landing and on depth and motion perception. These fields are then brought together in a discussion of visual cues available d...
