Traffic alert and collision avoidance event autoflight control system and method

An aircraft comprising:

• a memory configured to store autoflight commands of a Traffic alert and Collision Avoidance System (TCAS) event autoflight mode;
• and
• one or more processors coupled to the memory and configured to:
• receive an indication of a Traffic Advisory (TA) corresponding to a TCAS event;
• in response to the indication of the TA, automatically arm the TCAS event autoflight mode;
• receive an indication of a Resolution Advisory (RA) corresponding to the TCAS event;
• in response to the indication of the RA, automatically activate the TCAS event autoflight mode to automatically control the aircraft based on a type of the RA;
• prior to conclusion of the RA, receive an indication of a violation of an airspeed operational rule of the aircraft;
• in response to the indication of the violation, perform an RA airspeed protection operation, wherein the RA airspeed protection operation is identified based on the indication of the RA, and wherein the RA airspeed protection operation differs from a non-RA airspeed protection operation;
• prior to conclusion of the RA, receive an indication of a mode switch request to a TA-only mode;
• and
• in response to the indication of the mode switch request, perform a TA mode transition response operation.
