Relative navigation of an aircraft (fixed wing or helicopter) close to ships at sea is a unique navigation problem. Shipboard helicopter operations provide a difficult operational environment. Wind over deck and wake turbulence shed by ship super structure offer challenging and unpredictable conditions during takeoff and landing. This is especially true in the operational environment that inclu...

This paper handles a trajectory optimization of fixed wing aircraft perch landing assisted by thruster. The paper develops aircraft model and deals with six-degree-of-freedom motion for further understanding of dynamic phenomena of proposed landing method. The landing maneuver is described as an optimal control problem minimizing the fuel consumption with specified terminal landing conditions. ...

To ensure the operation safety of landing signal officer (LSO) to pilot during carrierbased aircraft landing, the paper proposed a “LSO-pilot-aircraft” instruction associated with operation system. LSO guide mission, and design instruction associated with operation element is been analysed. The relationship and matching of “LSO-pilotaircraft” system are exhibited by instruction associated with ...

Considering the precise landing demand for carrier-based aircraft flight control, this paper proposes an adaptive fuzzy control method strong time-varying, parameter uncertainty and various complex coupling in actual state model. This is applied to flap channel achieve direct lift system utilized approximate six-degree-of-freedom nonlinear model of a carrier that difficult accurately describe, ...

Human factors certification criteria are being developed for large civil aircraft to replace the interim policies currently in place for this purpose. The objective of these initiatives is to reduce the incidence of design induced error. Many formal error identification and prediction techniques currently exist, however none of these have been validated for their use in an aviation context due ...

A STATISTICAL SEPARATION STANDARD AND RISK-THROUGHPUT MODELING OF THE AIRCRAFT LANDING PROCESS Babak Ghalebsaz Jeddi, Ph.D. George Mason University, 2008 Dissertation Director: Dr. John F. Shortle In the context of a high demand for runways as important scarce resources of the national air transportation system, this dissertation is concerned with the problem of determining the best separation ...

We study robust hovering control of vertical/short takeoff and landing (V/STOL) aircraft. For hovering control, we can model a V/STOL aircraft as a planar vertical takeoff and landing (PVTOL) aircraft. We use a recently developed optimal control approach to design a robust hovering control. The resulting control is a nonlinear state feedback whose robustness is demonstrated by numerical simulat...

Due to the large increase in the density of aircraft arrivals at airports in recent years, it has become important to optimize the scheduling of aircraft landings in order to reduce wait time, improve airport efficiency, and minimize fuel consumption while maintaining safety. As the density of aircraft arrivals increases, however, so too does the complexity of trajectory planning and generation...

Page 5Pay attention to the “normal” landing path of an aircraft. In the case of a microburst, an aircraft will typically encounter a headwind that serves to slow and lift the nose of the aircraft above the normal landing path. A pilot may compensate for this condition by lowering the nose of the aircraft as it approaches the center of the downdraft core. Question: What problems may the pilot en...
