Benefits of technology

The patent is about a method and system for generating an aircraft display to show the estimated flight paths of two aircraft and the distance between them. This allows for the creation of a navigation alert region based on the expected separation violation condition, which is the area where the first aircraft may collide with the second aircraft if they fly into it. The display also includes a map and two graphical features representing the first and second aircraft, as well as the dimensions of the navigation alert region. The technical effect of this patent is to improve safety and prevent collisions between aircraft by providing a visual representation of the expected separation violation conditions.

Problems solved by technology

DAA systems can be used in conventional manned aircraft and for unmanned, remotely piloted aircraft, since in both situations the pilot can have limited access to the relevant airspace information.
Additionally, the SC228 Ph 1 MOPS document does not describe how to gather and analyze airspace data to generate a display including pilot-relevant information, and does not provide guidance on arranging such displays to reduce pilot workload.
Switching between go advice and no-go advice can lead to pilot confusion and increase pilot workload since the pilot has to evaluate each piece of information presented in the display in a timely manner to decide whether the information is go advice or no-go advice.
Some pilots may not find the dots 326 useful, or may find them distraction, in which case such pilots can adjust the settings 158 such that the dots 326 are not displayed.

Embodiment Construction

[0016]Implementations disclosed herein provide human machine interfaces that improve pilot situational awareness and reduce pilot workload by organizing data presented to the pilot in a manner that prioritizes the data and simplifies understanding of the data. Particular implementations are described herein with reference to the drawings. In the description, common features are designated by common reference numbers throughout the drawings. In some drawings, multiple instances of a particular type of feature are used. Although these features are physically and / or logically distinct, the same reference number is used for each, and the different instances are distinguished by addition of a letter to the reference number. When the features as a group or a type are referred to herein (e.g., when no particular one of the features is being referenced), the reference number is used without a distinguishing letter. However, when one particular feature of multiple features of the same type i...

Abstract

A method of generating an aircraft display includes determining an estimated first flight path of a first aircraft and determining an estimated second flight path of a second aircraft. The method also includes determining an estimated proximity of the first aircraft and the second aircraft based on the estimated flight paths. The method further includes, based on the estimated proximity indicating a projected separation violation condition, determining a navigation alert region. The method also includes generating a display that includes a map, a first graphical feature overlaying the map and representing of the first aircraft, a second graphical feature overlaying the map and representing of the second aircraft, and a third graphical feature overlaying the map and indicating dimensions of the navigation alert region.

Description

FIELD OF THE DISCLOSURE[0001]The present disclosure is generally related to an aircraft flight information system.BACKGROUND[0002]For automatically piloted aircraft, Detect and Avoid (DAA) systems use information descriptive of an airspace to make automated maneuvering decisions. For manned aircraft, DAA systems can greatly improve pilot situational awareness by providing the pilot with relevant data about the airspace. DAA systems can be used in conventional manned aircraft and for unmanned, remotely piloted aircraft, since in both situations the pilot can have limited access to the relevant airspace information.[0003]To improve DAA system operation and design, the Radio Technical Commission for Aeronautics (RTCA) has published a document entitled “SC228 Ph 1 Minimum Operational Performance Standard (MOPS),” which suggests minimum features of a DAA system, including some features of displays (or other human machine interfaces) used by DAA systems. Generally, the SC228 Ph 1 MOPS doc...
