When landing at a tower-controlled airport, what is a critical action to take?

When landing at a tower-controlled airport, a critical action is to clear the runway and then contact ground control. This procedure ensures that air traffic control is aware of the aircraft's position and can manage traffic effectively. After landing, it is essential to vacate the runway promptly to avoid potential conflicts with following aircraft and to maintain the safety and efficiency of airport operations.

Once the aircraft is clear of the runway, contacting ground control allows pilots to receive instructions for taxiing to the desired destination, whether it be to parking or another area on the airport. This communication is vital for maintaining situational awareness and ensuring that all movements are coordinated with the control tower's directives.

Engaging with ground control after clearing the runway exemplifies good airmanship and adherence to standard operating procedures, critical for ensuring safety in busy airspace.
