Remote Aircraft Preflight Verification via Wireless Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional preflight inspections are time-consuming and intrusive, often delaying flight departures, especially for smaller aircraft with limited crew availability.
Innovation Solution
A wireless system and method for remote aircraft preflight verification, utilizing sensors onboard the aircraft to transmit data to a remote interface for processing and presentation, allowing crew members to determine preflight readiness without physically inspecting the aircraft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a crew member physically inspects the aircraft by walking around and opening doors and panels, then comprehensive visual inspection of gauges and indicators is achieved, but the process becomes time-consuming and delays flight departures
Solution Approach 1:
The patent replaces the mechanical system of physical inspection (crew member walking, opening panels, visually checking gauges) with an electronic/data-based system. Sensors automatically collect data from aircraft components and transmit it wirelessly to a remote interface, eliminating the need for manual physical inspection while maintaining comprehensive monitoring of aircraft systems.
Solution Approach 2:
The aircraft system performs self-inspection through onboard sensors that automatically monitor components and transmit their status data. The sensors act as self-monitoring devices that continuously assess their own operational state without requiring external human intervention, thereby enabling autonomous preflight verification.
2Loss of information
If a crew member physically inspects the aircraft, then direct observation of component status is achieved, but the process becomes intrusive and delays departure
Solution Approach 1:
The patent replaces manual visual observation with automated sensor-based data collection. Instead of a crew member physically examining components, sensors mounted on or near the components automatically detect and transmit their status, providing complete information without any physical intrusion into the aircraft systems.
3Productivity
If remote sensor data transmission is implemented, then preflight inspection time is reduced, but system complexity increases with sensors, transmitters, and remote interface
Solution Approach 1:
The patent employs multi-functional components that perform multiple roles. For example, the wireless transmitters serve both as communication devices and as part of the data acquisition system. The remote interface consolidates multiple functions including data reception, processing, and presentation in a single system, thereby reducing overall complexity despite the addition of remote capabilities.
Data Source
AI summary
A remote aircraft preflight verification method includes sending a request via a remote interface for data from a sensor onboard an aircraft, transmitting the data from the sensor to the remote interface, processing the data via the remote interface to enable a determination that one or more preflight requirements are met, and presenting the data via the remote interface for enabling verification that the one or more preflight requirements are met. The method steps are repeated for multiple sensors. A remote aircraft preflight verification system includes sensors located onboard an aircraft and a remote interface communicatively coupled to the sensors. The remote interface includes a display for presenting data and an interface enabling verification of preflight readiness. The system may optionally include a wireless access point for coordinating the transmitting and receiving of instructions and data between the sensors and the remote interface.
