This study describes a novel, vision-based method for automatically obtaining the 3-DOF attitude of an aircraft. A very wide-angle view of the environment is captured and the input images are classified into fuzzy sky and ground regions using the spectral and intensity properties of the pixels. A novel approach to obtaining the 2-DOF attitude of the aircraft from the classified images is descri...

We design a feedback control architecture for longitudinal flight of an aircraft. The multi-level architecture includes the flight control loop to govern the short term dynamics of the aircraft, and the autopilot to control the long term modes. Using H∞ performance and robustness criteria, the problem is cast as a non-convex and non-smooth optimization program. We present a non-convex bundle me...

For solve the problem of flight simulation system accurately modeling, speediness and high efficiency implement. It brings forward flight simulation system of aerocraft speediness and integrative modeling method based on Aerosim/RTW. Compare with traditional development method for flight simulation system, the method that based on Aerosim/RTW could implement speediness prototype and integrative...

The problem of learning decision rules for sequential tasks is addressed, focusing on the problem of learning tactical plans from a simple flight simulator where a plane must avoid a missile. The learning method relies on the notion of competition and employs genetic algorithms to search the space of decision policies. In the research presented here, the use of available heuristic domain knowle...

Aviation display system designers and evaluators need to know how discriminable displayed symbols will be over a wide range of conditions to assess the adequacy and effectiveness of flight display systems. If flight display symbols are to be safely recognized by pilots, it is necessary that they can be easily discriminated from each other. Sometimes psychophysical measurements can answer this q...

We have developed a design for packaging Charged Coupled Devices (CCDs) for use as optical imaging devices for space applications, although the design is also useful for any large ground-based mosaic. We have constructed and assembled prototype packages using this design. Testing of these prototypes has demonstrated that these packaged CCDs are flight worthy. The design, construction, and testi...

To collect the information on devastated districts, it is effective to use helicopters. However, the operation using manned helicopters costs a lot. It is expected that the use of unmanned helicopters could reduce the cost of these tasks. It is known to be more difficult to operate unmanned helicopters remotely than to operate manned helicopters. The reason is that an operator cannot know the a...

This paper describes a modelling approach to the dynamics of the airplane flight aimed at designing and realizing a simple but realistic ‘‘flight simulator,’’ able to mimic the longitudinal behaviour of a real airplane. The model is implemented by using the Interactive Physics simulation environment. The simulator is used to reproduce all the phases of a complete flight of a light commercial ai...

A new Bayesian Network algorithm is proposed in this paper. When seeking more accurate results, this new algorithm, Negotiating Method with Competition and Redundancy (NMCR), has bigger scale in structure than other network models we proposed. Time needed for network training and speed in testing show that NMCR works well in estimating of arrival flight delay, especially in flight chains mainly...

In developing an aircraft simulation, a number of aircraft dynamic models are available with a range of fidelity. However, many applications of simulation also require a model of the flight control or of the pilot to realize their goals. These models can be difficult to implement using classical control methods and, in the case of flight control systems, may not be publicly available. This pape...
