Solution Overview

Problem

Pilots face challenges in accurately determining and verifying critical airspeeds (V-speeds) for aircraft, as existing systems lack effective methods for displaying and verifying these essential flight parameters, which can lead to potential errors during takeoff and landing.

Innovation Solution

A system and method that store aircraft data, calculate user-defined and calculated airspeeds, and display position difference indicators to help pilots visualize the difference between user-defined and calculated static positions, ensuring accurate airspeed determination and reducing errors by providing a graphical representation of these positions on a display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pilots manually determine and verify V-speeds, then flexibility and control are maintained, but accuracy and reliability are compromised due to human error

Engineering Contradiction:
Improveairspeed determination accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically calculates V-speeds using aircraft data from sensors and databases, eliminating the need for manual pilot calculation. The computer system serves itself by gathering data, performing computations, and presenting results without human intervention in the calculation process, thereby improving reliability while maintaining simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical calculation methods with an automated computer-based system. Instead of pilots manually computing V-speeds using formulas and reference materials, the system uses electronic data processing to automatically determine accurate airspeed values, substituting human cognitive effort with automated computational processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If computer systems automatically calculate V-speeds, then accuracy is improved, but pilot verification capability is reduced

Engineering Contradiction:
Improveairspeed calculation precisionVSAvoidpilot verification ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system provides calculated V-speeds to the pilot through the display interface, enabling the pilot to review and verify the automated calculations. This feedback mechanism allows the pilot to compare the computer-calculated values with expected ranges or manual calculations, maintaining verification capability while benefiting from automated precision.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The display system serves multiple functions: it presents calculated V-speeds to the pilot, allows for verification of these values, and can display additional flight information. This multi-functionality ensures that while automation improves precision, the pilot retains full verification capability through the same interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of information

If traditional dial gauges are replaced with digital displays, then information density is increased, but visual clarity and quick recognition are reduced

Engineering Contradiction:
Improveinformation delivery completenessVSAvoidvisual detection difficulty
Core Design Contradiction:
Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The system uses color-coded indicators and graphical representations on the display to enhance visual recognition of V-speed information. By employing distinct colors and visual patterns, the system maintains quick detection capability while delivering comprehensive digital information, overcoming the limitations of traditional monochrome dial gauges.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent transitions from two-dimensional analog dial displays to a multi-dimensional digital display interface that can present information in various formats including numerical values, graphical indicators, and color-coded warnings. This dimensional expansion allows complete information delivery while maintaining visual clarity through multiple representation modes.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A method and a system are provided for displaying flight information of an aircraft. The system receives at least one user defined airspeed related to flight of the aircraft from a user. A processor calculates the at least one calculated airspeed based on data stored in a memory device. A static position is determined by the processor for the user defined and calculated airspeeds. The difference between the positions developed from the user defined and calculated position is also calculated. A difference indicator is displayed to the user for the difference between each user defined and calculated position.
