Abstract
A system, device, and method for generating and presenting an aircraft attitude indicator are disclosed. The attitude indicator presenting system may include a presentation system comprised of one or more display units receiving image data from an image generator (IG). The IG may be configured to acquire navigation data and generate the image data as a function of the navigation data. The navigation data could include data representative of aircraft roll and/or pitch attitude, and the image data could be representative of at least of an image of the attitude indicator comprised of a sky area and a ground area. The ground area may be visually presented by either a first texture or a second texture depending on whether a trigger attitude has been met or exceeded.
Claims20
A system for presenting an aircraft attitude indicator, comprising:
- at least one display unit configured to:
- receive image data representative of an image of an aircraft attitude indicator provided by
- an image generator including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code and configured to:
- acquire navigation data representative of a roll attitude and a pitch attitude from a source of navigation data;
- and
- generate the image data as a function of the roll attitude and the pitch attitude, where
- the aircraft attitude indicator is comprised of at least a sky area and a ground area presenting one of a plurality of visual presentations, where
- a first visual presentation of the ground area includes a presentation that does not change when
- the roll attitude is less than or equal to a roll trigger attitude defining an unusual roll attitude, and
- the pitch attitude is less than or equal to a pitch trigger attitude defining an unusual pitch attitude, and
- a second visual presentation of the ground area includes a rough-textured presentation that moves within the ground area when the roll attitude or the pitch attitude is greater than or equal to the roll trigger attitude or the pitch trigger attitude, respectively;
- and
- present the image represented in the image data, whereby
- an optical flow of the rough-textured presentation, without a change to a presentation of the sky area, is provided when the unusual roll attitude or the unusual pitch attitude is being encountered.

- an image generator including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code and configured to:
- acquire navigation data representative of a roll attitude and a pitch attitude from a source of navigation data;
- and
- generate the image data as a function of the roll attitude and the pitch attitude, where

- a first visual presentation of the ground area includes a presentation that does not change when
- the roll attitude is less than or equal to a roll trigger attitude defining an unusual roll attitude, and
- the pitch attitude is less than or equal to a pitch trigger attitude defining an unusual pitch attitude, and
- a second visual presentation of the ground area includes a rough-textured presentation that moves within the ground area when the roll attitude or the pitch attitude is greater than or equal to the roll trigger attitude or the pitch trigger attitude, respectively, such that
- the image is presentable by at least one display unit to provide an optical flow of the rough-textured presentation, without a change to a presentation of the sky area, when the unusual roll attitude or the unusual pitch attitude is being encountered.

A method for generating an aircraft attitude indicator, comprising:
- acquiring, by at least one processor executing processor-executable code, navigation data representative of a roll attitude and a pitch attitude from a source of navigation data;
- and
- generating image data as a function of the roll attitude and the pitch attitude, where
- the image data is representative of an image of at least an aircraft attitude indicator comprised of at least at least a sky area and a ground area presenting one of a plurality of visual presentations, where
- a first visual presentation of the ground area includes a presentation that does not change when
- the roll attitude is less than or equal to a roll trigger attitude defining an unusual roll attitude, and
- the pitch attitude is less than or equal to a pitch trigger attitude defining an unusual pitch attitude, and
- a second visual presentation of the ground area includes a rough-textured presentation that moves within the ground area when the roll attitude or the pitch attitude is greater than or equal to the roll trigger attitude or the pitch trigger attitude, respectively, such that
- the image is presentable by at least one display unit to provide an optical flow of the rough-textured presentation, without a change to a presentation of the sky area, when the unusual roll attitude or the unusual pitch attitude is being encountered.
