Abstract
Embodiments are directed to obtaining data associated with at least one aircraft flight parameter when an aircraft is being operated in flight; processing the data to determine that the at least one aircraft flight parameter indicates a change in value in an amount greater than a threshold; and decoupling a load from the aircraft based on determining that the at least one aircraft flight parameter indicates the change in value in the amount greater than the threshold.
Claims19
A method comprising:
- obtaining data associated with at least one aircraft flight parameter when an aircraft is being operated in flight;
- processing the data to determine that the at least one aircraft flight parameter indicates a change in value in an amount greater than a threshold;
- and
- decoupling a load from the aircraft based on determining that the at least one aircraft flight parameter indicates the change in value in the amount greater than the threshold.
1 more element
An apparatus comprising:
- at least one processor;
- and
- memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to:
- obtain data associated with at least one aircraft flight parameter when an aircraft is being operated in flight;
- process the data to determine that the at least one aircraft flight parameter indicates a change in value in an amount greater than a threshold;
- and
- cause a load to be decoupled from the aircraft based on determining that the at least one aircraft flight parameter indicates the change in value in the amount greater than the threshold.
4 more elements
An aircraft comprising:
- a plurality of sensors configured to provide data pertaining to collective input, engine power, and shaft torque;
- and
- a control computer configured to:
- process the data to determine that at a weighted combination of the collective input, engine power, and shaft torque indicates a step change in value in an amount greater than a threshold magnitude as a function of time during flight;
- and
- cause a load to be decoupled from the aircraft based at least in part on determining that the weighted combination of the collective input, engine power, and shaft torque indicates the step change in value.
