Experimental Study of Vertical Flight Path Mode Awareness

Flight Path Angle Steering with Lambert Guidance Reference

In this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. Generally the Lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. Because of uncertainties and undesired factors, the nominal position and velocity obtained by Lambert technique need to be followed in actual flight. ...

Flight Trajectory Path Planning

The paper describes an application of the A* algorithm for flight path planning for airplanes with defined motion dynamics operating in a continuous three-dimensional space constrained by existing physical obstacles. The presented A* algorithm modification provides significant acceleration (reduction of the state space) of the path planning process. The described algorithm is able to find a pat...

UAV In-Flight Awareness Concept

This work proposes an innovative concept, called InFlight Awareness (IFA), expanding the concept of Sense And Avoid and aiming situational awareness in both controlled and non-controlled airspace for unmanned aircraft. From events occurring either internally or externally to the aircraft, the proposed system checks symptoms (taking into account the capabilities of the platform), data from both ...

Situation Awareness, Automation & Free Flight

Free flight represents a major change in the way that aircraft may be handled in the U.S. National Airspace System. It has the potential of significantly increasing airspace utilization and thus improving aircraft throughput. The degree to which these objectives can be met, however, without compromising aircraft safety, depends on establishing appropriate changes in the air traffic control syst...
