In the event of a TCAS RA, what is the prescribed action?

During a Traffic Collision Avoidance System (TCAS) Resolution Advisory (RA), the prescribed action is to disconnect the autopilot and follow flight director guidance. This is essential because the flight director provides real-time guidance on how to maneuver the aircraft to avoid a potential collision.

Disconnecting the autopilot allows the pilot to have full manual control over the aircraft, ensuring that immediate and precise actions can be taken to comply with the TCAS RA. The flight director uses the aircraft's parameters and current trajectory to display the recommended flight path, which is critical during a TCAS RA as it helps in making quick and correct decisions under stress.

While monitoring airspeed or engaging thrust might be important in specific flight situations, the immediate priority during a TCAS RA is to adjust altitude and heading according to the instructions provided by the flight director, ensuring a safe distance from other aircraft. This response prioritizes avoiding a collision effectively and efficiently in compliance with TCAS protocols.
