Solution Overview

Problem

Current pilot reporting systems, such as PIREPs, are limited by manual generation, lack of timeliness, and infrequent reporting, as they often require pilot intervention and are not automated effectively, leading to insufficient real-time and localized weather data for pilots to anticipate and react to meteorological events during flights.

Innovation Solution

A sensor-enhanced real-time automatic pilot report (PIREP) generating system that uses aircraft-based sensors to collect and analyze atmospheric data, allowing for automatic generation and transmission of reports to ground control facilities, with pilot input options for acceptance, amendment, or rejection, and a countdown timer for automatic reporting if no action is taken.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual PIREP generation is used, then pilot involvement and control are maintained, but timeliness and frequency of weather reporting are reduced

Engineering Contradiction:
Improvepilot control over reportingVSAvoidtime delay in weather reporting
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service by allowing the aircraft's sensor suite and control processors to automatically detect, analyze, and generate PIREPs without requiring pilot intervention. The system monitors atmospheric conditions continuously and autonomously determines when reporting is necessary, eliminating the time loss associated with manual generation while maintaining operational control through pilot override capabilities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by continuously monitoring atmospheric conditions and pre-generating PIREPs before pilots would manually create them. The control processors analyze sensor data in real-time and prepare reports ahead of time, ensuring immediate transmission capability when conditions warrant reporting, thus eliminating delays inherent in manual generation.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If automated PIREP generation is implemented, then timeliness and frequency of reporting are improved, but system complexity and automation extent increase

Engineering Contradiction:
Improvereporting time delayVSAvoidautomation system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system achieves universality by utilizing the aircraft's existing multi-functional sensor suite (weather radar, GPS, altimeter, temperature sensors) for PIREP generation rather than requiring dedicated automated reporting equipment. The control processors leverage already-present flight data and communication systems, thereby improving timeliness without proportionally increasing system complexity.

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

Solution Approach 2:

The control processors serve as an intermediary between the sensor suite and the reporting system, consolidating data from multiple sensors and translating it into standardized PIREP formats. This intermediary function simplifies the overall architecture by centralizing the processing logic rather than requiring direct complex interconnections between all system components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If frequent automated reporting is enabled, then weather data frequency and localization are improved, but friction in the reporting process increases

Engineering Contradiction:
Improveweather reporting frequencyVSAvoidreporting friction
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system eliminates reporting friction by implementing self-service automation where the aircraft autonomously monitors conditions and generates reports without pilot intervention. The control processors continuously assess whether reporting conditions exist and automatically transmit PIREPs, achieving frequent reporting while maintaining ease of operation through complete automation rather than requiring repeated pilot actions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system achieves continuity of useful action by maintaining continuous monitoring of atmospheric conditions through the sensor suite and continuously evaluating whether reporting thresholds are met. This continuous operation enables frequent reporting without interruption or friction, as the system operates autonomously throughout the flight without requiring pilot engagement for each report.

Inventive Principle:
Principle #20Continuity of useful action

4Measurement precision

If pilot intervention is required for PIREP generation, then accuracy and relevance of reports are maintained, but timeliness and localization are reduced

Engineering Contradiction:
Improveweather data accuracyVSAvoidreporting delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system implements feedback mechanisms where the control processors continuously receive feedback from sensor data, analyze it against predefined criteria, and automatically generate reports when conditions warrant. This closed-loop feedback system maintains accuracy by using real-time sensor inputs while eliminating the time delays associated with manual pilot intervention and ATC coordination.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary analysis of atmospheric conditions continuously, preparing accurate and relevant PIREPs before they are needed. By pre-analyzing sensor data and pre-generating reports based on current conditions, the system ensures both accuracy and timeliness, eliminating the trade-off between manual review and rapid reporting.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system and method for sensor-enhanced real-time automatic pilot report (PIREP) generation is disclosed. In embodiments, the PIREP generation system includes control processors in communication with a variety of aircraft-based sensors. Diverse sensors collect atmospheric data of meteorological conditions in the vicinity of the aircraft and/or its flight path. The PIREP generating system analyzes the collected datasets and determines whether the collected datasets meet criteria for reportable weather conditions. Reportable data are displayed to the pilot via an interactive display device whereby the pilot may accept, abort (e.g., opt out), or augment the data with additional information provided by the pilot. If the pilot aborts the PIREP, no further action is taken. Otherwise (e.g., if the pilot accepts, augments, or takes no action), a PIREP is automatically generated based on the displayed (or amended) reportable data. The generated PIREP is automatically transmitted to ground control.
