Generation of approach and landing trajectories with operational constraints for aircraft with multiple degrees of freedom

A computer-implemented method comprising:

• receiving or determining one or more operational constraints corresponding to an aircraft having multiple degrees of freedom;
• generating a reference trajectory between a takeoff location and a landing location;
• performing an optimization method by:
• determining that the reference trajectory does not meet an operational constraint of the one or more operational constraints;
• responsive to determining that the reference trajectory does not meet the operational constraint, iteratively adjusting a temporal state parameter of the reference trajectory until a set of trajectory data corresponding to an adjusted trajectory meets the one or more operational constraints, wherein the set of trajectory data comprises:
• a set of temporal state parameters that describe a state of the aircraft along the adjusted trajectory;
• and
• a set of control input signals that are usable to control the aircraft to execute the set of temporal state parameters;
• and
• transmitting the set of trajectory data to a flight computer that is configured to control the aircraft along the adjusted trajectory based on the set of trajectory data.

A non-transitory computer-readable medium having instructions that are executable by a processing device for causing the processing device to:

• receive one or more operational constraints corresponding to an aircraft having multiple degrees of freedom;
• generate a reference trajectory between a takeoff location and a landing location;
• perform an optimization method by:
• determining that the reference trajectory does not meet an operational constraint of the one or more operational constraints;
• responsive to determining that the reference trajectory does not meet the operational constraint, iteratively adjusting a temporal state parameter of the reference trajectory until a set of trajectory data corresponding to an adjusted trajectory meets the one or more operational constraints, wherein the set of trajectory data comprises:
• a set of temporal state parameters that describe a state of the aircraft along the adjusted trajectory;
• and
• a set of control input signals that are usable to control the aircraft to execute the set of temporal state parameters;
• and
• transmit the set of trajectory data to a flight computer, the flight computer being configured to control the aircraft along the adjusted trajectory based on the set of trajectory data.
