The information needed depends strongly upon the current task. For example, in terrain following flight pilots need cues about the structure of the terrain contour. Beckett, Peter (). Effective cueing during approach and touchdown -Comparison with flight.

The chapters in this book describe a general sequence of tasks that are required to perform to create terrain databases for a realtime simulation, and some of the things you need to consider when doing each step.

The tasks include the following: • Planning - Set some goals for what your simulation. shown a non-classified demo of the mission trainer. It was a flight simulation application that was running on a high end Unix workstation. I estimate the workstation cost at perhaps $, The application allowed a pilot to “fly” over extremely realistic terrain created by overlaying satellite imagery on top of a topographic elevation mesh.

window visual cues to estimate and detect changes in altitude ([2] and references therein). As this can be a high-risk task it would be beneficial to be able to do some training in a low-risk environment such as a simulator.

In order for the training to be effective the important visual cues need to be present in the visual. emphasis on low-level flight. Research will be reviewed that addresses: (1) the visual cues used under normal, optimal visual flight con-ditions; (2) the visual cues available and their usage under such degraded conditions as night flight, weather, or sensor usage; and, finally, (3) the enhancement of visual cues through advanced technology.

TERF = terrain flight TFH = total flight hours VFR = visual flight rules I. Introduction elicopter overland navigation is a necessary but challenging mission area that is also a complex cognitive task.

Low-level navigation, or “terrain flight” (TERF), is defined as overland flight below feet above ground level (AGL) 1. This environment.

A study was conducted to determine if primary flight displays (PFDs) depicting terrain could be used with a level of safety equivalent to electronic attitude-direction indicators (EADIs) without terrain.

Five groups of 8 pilots each flew scenarios in a flight simulator using one of three PFDs (EADI, full-color terrain, uniformly. Degraded visual conditions present a great challenge to rotary-wing aircraft.

These conditions can obscure cues used to interpret speed, location and approach. With such cues obscured, pilots must rely on in-cockpit instrumentation, increasing workload, whilst reducing situation awareness. When operating within degraded visual conditions, pilots require easy access to flight critical.

Large scale terrain tessellation in flight simulator visual system Abstract: In order to solve the problem of high CPU usage and long rendering time in large scale terrain rendering in the flight simulator visual system, a GPU-based terrain tessellation algorithm is presented.

We introduce an adaptive tessellation factor model combines screen. Terrain visual databases are accurate and interactive representations of real geographic areas. Each visual database is designed and built to perfectly fit the type of application it is used in. Terrain size, resolution, and detail level are perfectly balanced with performance in order to provide a realistic and immersive experience for trainees and system operators.

Toward this end, we have begun by examining flight control strategies in a minimally complex simulation of a visual hover task (see Fig. Unfortunately, this book can't be printed from the OpenBook.

Each of four flying tasks (approach and landing, formation flying, aerial refueling, and low level flight) was subjected to task analysis/cue requirements determination in order to determine what tasks required depth judgments.

Using custom designed flight display images and a novel Flicker Paradigm, an experiment was designed to measure pilot response time to visual cues on both SVS and conventional electronic displays and also for different levels of pilot experience.

Results indicated that change detection was impaired with the SVS display across the pilot ranks. Part of the Lecture Notes in Computer Science book series (LNCS, volume ) Abstract.
