What is the primary task of the flight crew immediately after touchdown?

The primary task of the flight crew immediately after touchdown is to slow the aircraft down. This involves using various systems, such as the thrust reversers and brakes, to bring the aircraft safely to a complete stop on the runway. Effective deceleration is crucial for ensuring passenger safety and for managing the aircraft's energy upon landing.

Once the aircraft has touched down, the crew must carefully monitor speed, maintain control, and prepare for taxiing to the gate or designated area. This process includes managing the aircraft's speed in relation to runway conditions and any potential obstacles.

While engaging the autopilot is typically a procedure during flight, it is not relevant immediately after landing. Pre-takeoff checks are conducted before departure, not after landing. Finally, preparing for cargo unloading comes after the aircraft has slowed and safely reached the gate; it is not an immediate task following touchdown.
