Definitions
- This invention relates to the field of aircraft displays and more specifically to the representation of wires detected by a wire detection system as seen by an aircraft flight crew.
- Electronic displays are replacing mechanical flight instruments in aircraft (glass cockpit) at an ever-increasing rate. These electronic displays typically display pictorial representations (display formats) of existing instruments, but can also display other formats such as checklists or diagnostics.
- a horizontal situation indicator (HSI) shows a god's eye view of the aircraft with respect to the earth; digital maps also use this god's eye view representation.
- an attitude indicator (ADI) also l ⁇ iown as a vertical situation display, shows a pilot's eye view looking out of the aircraft cockpit; ADI symbology includes simulated sky (blue), earth (brown), and an artificial horizon.
- FIG. 1 a prior art attitude director indicator (ADI) display format is shown herein FIG. 1.
- ADI attitude director indicator
- FIG. 1 An aircraft is symbolically represented, made up of a left wing 1, a right wing 2, and a nose 3.
- a sky region 11, colored blue, an earth region 12, colored brown, and a horizon line 13, colored white symbolically represent the environment scene outside the aircraft.
- Aircraft attitude is represented by a moving pitch ladder 14 and a roll pointer 15 in conjunction with a roll scale 16.
- Basic operation of aircraft attitude indicators is well l ⁇ iown in the art and will not be discussed further herein.
- My invention consists of an improved vertical situation display apparatus with associated display formats for quickly conveying to an aircraft pilot the output from a wire detection system.
- a vertical situation display apparatus in accordance with my invention is especially suitable for helicopters that are conducting low-level operations near populated areas.
- this invention can be combined with an active laser wire detection system.
- my invention can be implemented on non-glass cockpit aircraft by installation of a bezel ring on one or more of the existing attitude director indicators (ADI).
- ADI attitude director indicators
- FIG. 1 illustrates a prior art attitude indicator display format suitable for display on an electronic flight instrument system (EFIS).
- EFIS electronic flight instrument system
- FIG. 2 illustrates a wire detection display format suitable for display on an aircraft multifunction display (MFD), in accordance with one illustrative embodiment of my invention.
- MFD aircraft multifunction display
- FIG. 3 illustrates an attitude indicator display format with additional wire detection symbology, suitable for display on either an electronic flight instrument system (EFIS) or a multifunction display (MFD), in accordance with an embodiment of my invention.
- EFIS electronic flight instrument system
- MFD multifunction display
- FIG. 4 illustrates wire detection symbology, suitable for use on an attitude indicator display format in accordance with the embodiment of my invention depicted in FIG. 3.
- FIG. 5 illustrates a bezel ring, suitable for installation on a mechanical attitude director indicator (ADI) in accordance with an embodiment of my invention.
- ADI mechanical attitude director indicator
- FIG. 2 which shows one embodiment of my invention
- a display format including a grid 20 with x-coordinate of relative bearing 21 and y-coordinate of relative pitch elevation angle 22 is shown. Additionally, a colored range legend 23 and a number of colored wire-detected bars (30A-30F, 31A and 31B) are shown.
- this display format comprising colored horizontal lines is presented to the aircraft pilot on a 5-inch by 7-inch color active matrix liquid crystal display (AMLCD).
- AMLCD active matrix liquid crystal display
- the colors associated with each of the horizontal lines represent the distance from the aircraft to the detected wires as shown in the range legend 23.
- the detected wires that are located at a maximum detection range for example 750 meters, are represented by a first color (green).
- the detected wires that are located at a range that represents a non-immediate threat to the aircraft, for example between 300 to 500 meters, are represented by a second color (yellow).
- the detected wires that are located at a range that represents an immediate threat to the aircraft are represented by a third color (red).
- this color scheme gives the aircraft pilot both a sense of urgency regarding the potential threat and also cueing regarding the wire distance.
- a set of colored wire detected bars (40A, 40B, 41A, 41B, 42A, and 42B) are represented on a modified ADI pitch ladder 45, in conjunction with a modified aircraft symbol 46.
- each LED is capable of displaying three colors, red yellow, and green.
- each LED incorporates a night vision goggle (NVG) filter.
- NVG night vision goggle
- an aircraft equipped with a wire detection system is operated in the vicinity of wires.
- the existing wire detection system in the aircraft provides range, elevation and azimuth data for each of the detected wires.
- a computer in the aircraft converts the range data provided by the wire detection system into an urgency level such as an advisory, a caution, or a warning, as is l ⁇ iown.
- the aircraft computer converts the azimuth and elevation data into relative bearing and relative pitch elevation angle.
- the urgency level, relative bearing and relative pitch elevation angle of each detected wire are presented to the pilot in the form of wire-detected bars by either an attitude display format or the bezel of a mechanical ADI, in accordance with my invention and as described previously.
