Solution Overview

Problem

Current methods for wake turbulence avoidance in aviation rely heavily on pilot estimation and visual awareness, which can lead to human error and increased risk due to the complexity of estimating wake vortex position and longevity, especially in busy airspace.

Innovation Solution

A system that transmits flight information from a lead aircraft to a trailing aircraft, allowing the creation of a positional history to determine relative positioning and display differential flight parameters, enhancing situational awareness and aiding in wake turbulence avoidance.

1Reliability

If pilots rely on visual awareness and estimation to avoid wake turbulence, then wake turbulence avoidance can be achieved without additional equipment, but human error increases and safety decreases

Engineering Contradiction:

Solution Approach 1:

The patent introduces an intermediary system consisting of a transceiver and processor that automatically receives flight information from lead aircraft, creates positional history, determines differential flight parameters, and presents wake situational awareness information to the pilot. This intermediary handles the complex calculations and data processing, reducing pilot task complexity while improving safety through automated, accurate wake turbulence avoidance guidance.

Inventive Principle:

2Reliability

If pilots increase spacing between aircraft to avoid wake turbulence, then wake turbulence encounters are reduced, but airspace throughput and traffic management efficacy decrease

Engineering Contradiction:

Solution Approach 1:

The patent implements a feedback system where the transceiver continuously receives flight information from lead aircraft, the processor analyzes positional history and determines differential flight parameters in real-time, and the system presents updated wake situational awareness information to the pilot. This continuous feedback loop enables dynamic, precise spacing adjustments based on actual wake turbulence risk, allowing closer aircraft spacing when safe and maintaining high airspace throughput while ensuring wake turbulence avoidance.

Solution Approach 1:

The patent replaces the manual mechanical estimation process with an automated electronic system. The transceiver automatically receives precise flight information data from lead aircraft, the processor computationally determines differential flight parameters including wake vortex position and longevity, and the system presents accurate wake situational awareness information to the pilot. This substitution of manual estimation with automated electronic calculation dramatically improves measurement precision while managing system complexity through integrated hardware-software architecture.

AI summary

There are provided systems and methods for enhancing wake turbulence situational awareness in the cockpit of an aircraft. In one aspect, transmissions from a lead aircraft are received and stored by a trailing aircraft to allow the trailing aircraft to create a history of the lead aircraft's position for the purposes of, among other things, determining the relative positioning of the lead and the trailing aircraft (or trailing aircraft's) flight paths and relative altitudes. From this determination, better situational information can be displayed to the flight crew to aid in wake turbulence avoidance.
