What action should be taken immediately after initiating a go-around in the CRJ?

The most appropriate action to take immediately after initiating a go-around in the CRJ is to engage full power and climb. This action is critical because during a go-around, the aircraft must quickly and efficiently gain altitude to ensure safety and create separation from the runway and any obstacles. Full power is necessary to achieve a positive rate of climb, which is imperative for avoiding a potential mishap if the go-around was initiated due to an unexpected scenario, such as an unstable approach or a conflict on the runway.

Engaging power fully allows the aircraft to accelerate and achieve the climb performance necessary while the pilots reconfigure for the climb phase. Properly executing this step sets up the flight for a successful transition to the next phase of flight, typically re-entering the traffic pattern or proceeding to a new approach.

In this context, the other options do not address the immediate requirement of gaining altitude effectively in a go-around scenario. While establishing a retreat to the initial approach altitude or stabilizing speed might be important in other phases of flight, they are not the first priority after a go-around is initiated. Transferring control back to the first officer could also be relevant, but the first action must be to ensure the aircraft is in a safe handling configuration with sufficient climb
