System, module, and method for varying the intensity of a visual aid depicted on an aircraft display unit
First Claim
1. A system for varying the display of at least one visual aid depicted on an aircraft display unit, said system comprising:
- a data source for providing navigation data;
a data source for providing navigation reference data;
an image generating processor, wherein such processorreceives navigation data representative of aircraft position,receives navigation reference data representative of at least one visible feature which corresponds to the aircraft position,generates visual aid data representative of at least one variable-intensity visual aid, whereeach visual aid is representative of a visible feature located in the scene outside of the aircraft, andthe intensity of each visual aid varies, where such variation is based upon at least one quality parameter of the navigation data, navigation reference data, or both, andprovides the visual aid data to an aircraft display system; and
the aircraft display system, whereby the varying intensity of each visual aid depicts a fading-in effect of the visual aid in the direction of the horizon on at least one display unit.

Abstract
A present novel and non-trivial system, module, and method for varying the intensity of a visual aid depicted on an aircraft display unit. Visual aids could represent visible features such as markings on a runway surface. Data representative of visual aids may be provided by a navigation reference data source with errors inherent in the data which may be measured by one or more quality parameters. Also, errors associated with quality parameters are inherent in navigation data which provided positional information. Because of these errors, the depiction of visual aids on an egocentric display unit may appear misaligned with the corresponding visible feature. To compensate for the misalignment, an image generating processor generates visual aid data representative of at least one variable-intensity visual aid, wherein the intensity of each visual aid varies and such variation is based upon at least one quality parameter of the data.
