Problems solved by technology

The proportional size of the horizontal status indicator thus compresses other indicators, such as aircraft attitude, altitude, vertical speed, and horizontal airspeed indicators, thereby reducing the visual resolution of them by the flight crew and possibly negatively affecting Situation Awareness of Flight Crew

Embodiment Construction

[0015] The exemplary methods and systems described herein overcome at least some of the disadvantages of known primary flight display systems by providing a horizontal status indicator (HSI) that utilizes less horizon of the primary flight display. The displayed HSIs described herein are angled so that the pointer appears as a three-dimensional (3D) object on a two-dimensional (2D) display. As a result of the angled perspective of the displayed HSI, only the portion of the displayed HSI that is immediately available to the flight crew is displayed. Furthermore, as a result of the displayed HSI's angled perspective, when the aircraft changes its heading, the heading indicating portion of the HSI appears to rotate, thereby preserving the useful portion of the HSI on the primary flight display. Therefore, keeping only the useful portion of the HSI on the primary flight display and not displaying the unused portion facilitates the expansion of the residual indicator to use a great...

Abstract

The invention discloses a system and method for improving viewability of a primary flight display. An aircraft management system is used in displaying a primary flight display screen (100). The primary flight display screen has a predetermined height (H) and includes a horizontal situation indicator (HSI) (102). The aircraft management system includes a processor and a memory device operatively coupled to the processor. The memory device includes programmed computer instructions that instruct the processor to display the HSI for an aircraft. The HSI includes a receding perspective to simulate a three-dimensional (3D) object.

Description

technical field [0001] The field of the invention relates generally to display devices, and more specifically, to a method and system for increasing the visual resolution of a primary flight display screen. Background technique [0002] At least some known aircraft include a primary flight display system that includes continuous flight status input to the flight crew, eg, the pilot, co-pilot, and / or aircraft navigator. Such information usually includes the aircraft's attitude, altitude, vertical speed, horizontal airspeed, and horizontal state, for example, the heading of the aircraft. Additionally, this information helps improve situational awareness. Situational awareness is defined as the continuous and conscious awareness of the flight crew, eg, pilot and co-pilot, of the complex and dynamic relevant elements of the current flight environment. These elements may include other aircraft, weather conditions, and known physical states of the aircraft. This situational awa...
