Abstract
A system for weight measurement for an aircraft having a weight on wheels threshold between a flight mode and a ground mode includes a weight on wheels sensor arrangeable on a landing gear assembly of the aircraft, and a computing device receiving first detected data from the sensor related to strain on the landing gear assembly. The computing device calculates a rate of change of the strain over time to determine when the landing gear assembly reaches the weight on wheels threshold. The system also measures aircraft gross weight in a static condition.

A system for weight measurement for an aircraft, the aircraft having a weight on wheels threshold between a flight mode and a ground mode, the aircraft system comprising:
- a weight on wheels sensor arrangeable on a landing gear assembly of the aircraft;
- and,
- a computing device receiving first detected data from the sensor related to strain on the landing gear assembly, the computing device calculating a rate of change of the strain over time to determine when the landing gear assembly reaches the weight on wheels threshold.
A system for weight measurement of an aircraft having a weight on wheels threshold between a flight mode and a ground mode, the system comprising:
- a landing gear assembly;
- and,
- at least one of a weight on wheels sensor and a gross weight sensor arranged on the landing gear assembly to detect weight-related strain, wherein the weight on wheels sensor is tuned to a weight range having an upper weight limit approximately equal to the weight on wheels threshold, and the gross weight sensor is tuned to a weight range having a lower weight limit of approximately empty gross weight of the aircraft.
An aircraft having a weight on wheels threshold between a flight mode and a ground mode, the aircraft comprising:
- a landing gear assembly;
- and,
- a system for weight measurement including:
- a weight on wheels sensor arrangeable on the landing gear assembly;
- and,
- a computing device receiving first detected data from the sensor related to strain on the landing gear assembly, the computing device calculating a rate of change of the strain over time to determine when the landing gear assembly reaches the weight on wheels threshold.
