Mobile Device OOOI Logging via Motion Vectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for capturing and transmitting OOOI (Gate Out, Wheels Off, Wheels On, Gate In) data from aircraft are either manual and labor-intensive or rely on sensors that can be inaccurate and inconsistent across different aircraft types.
Innovation Solution
A mobile device onboard the aircraft uses motion sensors and a clock to automatically log OOOI times by identifying acceleration and deceleration vectors, eliminating the need for manual recording and improving accuracy through optional location sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual recording of OOOI times is used, then crew workload is high, but the system is simple and requires no additional equipment
Solution Approach 1:
The mobile device automatically detects and records OOOI events using its own motion sensors and processing capabilities, without requiring manual input from flight crews. The device serves itself by autonomously identifying acceleration patterns corresponding to gate out, wheels off, wheels on, and gate in events, and storing the associated timestamps.
Solution Approach 2:
The patent replaces the manual mechanical recording process with an automated electronic system using the mobile device's motion sensors, clock, and data processing capabilities. The system detects physical acceleration events and converts them into digital timestamps, eliminating the need for manual note-taking and verbal reporting.
2Extent of automation
If ACARS with aircraft sensors is used, then OOOI data collection is automated, but measurement precision is reduced due to sensor inaccuracies and inconsistencies
Solution Approach 1:
The patent uses a mobile device as a portable copy of the aircraft's motion sensing capabilities. Instead of relying on the aircraft's fixed sensors, the mobile device creates an independent measurement system that can be positioned optimally and processed independently, producing a duplicate but more accurate record of OOOI events.
Solution Approach 2:
The patent changes the measurement parameters by using the mobile device's high-precision accelerometers and clock instead of the aircraft's existing sensors. The system detects specific acceleration thresholds and patterns that correspond to OOOI events, using refined parameter detection to improve measurement precision over traditional aircraft sensor systems.
3Productivity
If manual recording and verbal relay of OOOI times is used, then equipment requirements are minimal, but productivity is reduced due to multiple manual steps
Solution Approach 1:
The patent merges the functions of detection, timing, recording, and data storage into a single mobile device. The motion sensor detects events, the clock timestamps them, the processor analyzes the data, and the storage medium saves the records - all in one integrated system, eliminating the need for separate manual processes and equipment.
Solution Approach 2:
The patent replaces the manual mechanical process of recording and relaying information with an automated electronic system. The mobile device automatically captures, processes, and stores OOOI data, eliminating the multiple manual steps of writing down times, verbally relaying them, and manually entering them into systems.

AI summary
Devices and methods for providing a retrievable record of the times of the actual aircraft movements such as the Gate Out time when the aircraft leaves the gate or parking position, the Wheels Off time when the aircraft takes off, the Wheels On time when the aircraft touches down during landing, and the Gate In time when the aircraft arrives at the gate or parking position (OOOI times). A mobile device for logging data onboard an aircraft comprises: a motion sensor; a clock; a non-transitory tangible computer-readable storage medium for storing motion data from the motion sensor and associated time data from the clock; and a data processing system configured to identify stored motion data representing respective acceleration/deceleration vectors of the mobile device motions that correspond to aircraft gate departure and arrival and aircraft takeoff and landing. The OOOI times are automatically logged in the non-transitory tangible computer-readable storage medium.
