Abstract

A system and method for automation of flight functions across an aircraft cockpit provides an open systems architecture to meet next generation mission capabilities for increased aircrew effectiveness. A mission reasoner (MR) receives inputs from a vehicle health system, mission phase analysis, and external assets (wingmen) to build a decision network based on a knowledge database providing a decision aid to automate flight functions across the cockpit. The MR reduces crew workload by providing an automated decision aid and increased situational awareness of own ship aircraft and cooperating nearby vehicle health status relating to a phase of mission success. The MR provides predictive decisions and alternative actions to complete one or more desired mission objectives and determines predictive maintenance and future failures to optimize condition-based maintenance and reduce cost.

a plurality of modules, the plurality of modules comprising:
a mission planning module configured for planning a mission;
a mission execution module comprising an execution command of the mission and a phase of mission analysis, wherein the phase is indicative of at least one of a pre-mission phase, an enroute phase, or a target area phase;
a mission assessment module configured to measure a mission performance against a benchmark indicative of successful performance; and
a vehicle health system configured for monitoring at least one subsystem onboard the aircraft, the vehicle health system comprising a multi-vehicle health interface configured for monitoring a vehicle status of a plurality of vehicles offboard the aircraft;

receive the execution command of the mission and a mission execution status from the mission execution module;
receive a phase of mission from the mission assessment module;
receive, from the vehicle health system, 1) a subsystem status of the at least one subsystem onboard the aircraft and 2) the vehicle status of at least one vehicle of the plurality of vehicles offboard the aircraft;
determine 1) a subsystem degraded status of the at least one subsystem onboard the aircraft based on the received subsystem status and 2) a vehicle degraded status of at least one vehicle of the plurality of vehicles offboard the aircraft based on the received vehicle status;
correlate each of the subsystem degraded status and the vehicle degraded status with the phase of mission;
determine a probability of mission success based on the correlation;
determine at least one predictive decision aid based on 1) the subsystem degraded status, 2) the vehicle degraded status, and 3) the phase of mission, and 4) the probability of mission success the at least one predictive decision aid one of: a subsystem procedure onboard the aircraft, a mission go of the mission, at least one mission retask of the mission, and a mission no go of the mission;
execute the at least one predictive decision aid;
communicate the at least one predictive decision aid to each of the plurality of modules; and
present the at least one predictive decision aid via the HMI to one of:

an operator and a supervisor of the aircraft,

8. The system for automation across an aircraft cockpit of claim 1 , wherein the conditional probability of failure is based at least in part on a categorical scale of a remaining useful life (RUL) of the at least one relevant component, the categorical scale one of: a failed state, a degraded state, or a working state.

9. The system for automation across an aircraft cockpit of claim 1 , wherein the at least one mission retask further comprises at least one secondary task of one of the aircraft and the at least one vehicle based on an output of the mission planning module.
