Method and system for triggering an emergency measure
First Claim
1. A method for triggering a plurality of emergency measures associated with an aircraft emergency, the method comprising determining a risk level for an aircraft emergency by evaluating a plurality of flight parameters or aircraft parameters using a predefined logic,wherein for each emergency measure of the plurality of emergency measures a threshold is defined and each emergency measure of the plurality of emergency measures is only triggered if the determined risk level exceeds the threshold defined for the emergency measure,wherein at least one emergency measure of the plurality of emergency measures is only triggered if the risk level exceeds a threshold defined for the at least one emergency measure and a calculated time-until-impact is less than a predetermined time-until-impact, orwherein at least one emergency measure is not triggered though the risk level exceeds the threshold defined for the at least one emergency measure if the calculated time-until-impact is less than a predetermined time-until-impact.

Abstract
A method for triggering a plurality of emergency measures associated with an aircraft emergency is disclosed. The method includes determining a risk level for an aircraft emergency by evaluating a plurality of flight parameters and/or aircraft parameters using a predefined logic. For each emergency measure of the plurality of emergency measures a threshold is defined and each emergency measure of the plurality of emergency measures is only triggered if the determined risk level exceeds the threshold defined for the emergency measure. Further, a system for use onboard an aircraft for triggering a plurality of emergency measures associated with an aircraft emergency and an aircraft comprising such a system are disclosed.

1. A method for triggering a plurality of emergency measures associated with an aircraft emergency, the method comprising determining a risk level for an aircraft emergency by evaluating a plurality of flight parameters or aircraft parameters using a predefined logic,
wherein for each emergency measure of the plurality of emergency measures a threshold is defined and each emergency measure of the plurality of emergency measures is only triggered if the determined risk level exceeds the threshold defined for the emergency measure, wherein at least one emergency measure of the plurality of emergency measures is only triggered if the risk level exceeds a threshold defined for the at least one emergency measure and a calculated time-until-impact is less than a predetermined time-until-impact, or wherein at least one emergency measure is not triggered though the risk level exceeds the threshold defined for the at least one emergency measure if the calculated time-until-impact is less than a predetermined time-until-impact.

8. A system for use onboard an aircraft for triggering a plurality of emergency measures associated with an aircraft emergency, wherein the system comprises a control unit,
wherein the control unit is adapted to receive a plurality of flight parameters or aircraft parameters from a control system of the aircraft and to determine a risk level for an aircraft emergency by evaluating the plurality of flight parameters or aircraft parameters received from the control system using a predefined logic, wherein the control unit is adapted to define for each emergency measure of the plurality of emergency measures a threshold and to trigger each emergency measure of the plurality of emergency measures only if the determined risk level exceeds the threshold defined for the emergency measure, wherein the control unit is further adapted to trigger at least one emergency measure of the plurality of emergency measures only if the risk level exceeds a threshold defined for the at least one emergency measure and a calculated time-until-impact is less than a predetermined time-until-impact.

15. A method for triggering a plurality of emergency measures associated with an aircraft emergency, wherein the method comprises determining a risk level for an aircraft emergency by evaluating a plurality of flight parameters or aircraft parameters using a predefined logic,
wherein for each emergency measure of the plurality of emergency measures a threshold is defined and each emergency measure of the plurality of emergency measures is only triggered if the determined risk level exceeds the threshold defined for the emergency measure, wherein for at least one phase of flight at least one flight parameter or aircraft parameter of the flight or aircraft parameters evaluated for determining the risk level is classified as irrelevant, that if the risk level exceeds the threshold defined for at least one emergency measure, the predefined logic provides the specific flight parameters or aircraft parameters that have caused the risk level to exceed the respective threshold, and that if a present phase of flight is the at least one phase of flight for which at least one flight or aircraft parameter has been classified as irrelevant and if the flight parameters or aircraft parameters having caused the risk level to exceed the respective threshold are among the at least one flight or aircraft parameter that have been classified as irrelevant, the emergency measure is not triggered.
