What do pilots say to ATC before taking off?

Pilot-ATC Communication Before Takeoff: A Critical Dialogue for Safe Skies

Before any aircraft ascends into the vast expanse of the sky, a crucial conversation takes place between the pilot and air traffic control (ATC). This pre-flight communication is an essential component of aviation safety, ensuring a smooth and coordinated departure process.

Confirmation of Readiness

As the pilot prepares for takeoff, they initiate contact with ATC, typically through a VHF radio. The pilot’s initial transmission confirms their readiness to depart and includes the following information:

• Aircraft call sign (e.g., “Delta 123”)
• Request for takeoff clearance (e.g., “Delta 123, request takeoff”)
• Runway number (e.g., “Runway 27”)

Clearance for Departure

Once the pilot’s request is received, ATC will respond with a clearance for departure if the airspace is clear. This clearance may include instructions for the takeoff procedure, such as:

• Runway alignment (e.g., “Align runway 27”)
• Specific departure route (e.g., “After takeoff, turn left to heading 120”)
• Altitude restrictions (e.g., “Maintain 3,000 feet until further advised”)

Expression of Gratitude

Upon receiving clearance, the pilot acknowledges and expresses gratitude for ATC’s assistance. This simple but important gesture reinforces the collaborative nature of aviation and fosters a positive working relationship between pilots and air traffic controllers.

• “Delta 123, thank you”
• “Roger, Delta 123”

Conciseness and Professionalism

Throughout the pre-flight communication, pilots and air traffic controllers maintain a concise and professional tone. Clarity and accuracy in their transmissions are paramount to ensure proper coordination and avoid any misunderstandings.

• Pilots use standard phraseology to convey their intentions (e.g., “request takeoff,” “roger”)
• ATC provides clear and concise instructions, using specific terminology and avoiding ambiguity

Safety First

The pre-flight communication between pilots and ATC is not merely a formality; it is a vital safety measure. It ensures that aircraft depart in an orderly and safe manner, minimizing the risk of collisions or incidents.

By confirming readiness, receiving clearance for departure, and expressing gratitude, pilots and air traffic controllers work together to establish a safe and efficient transition from the ground to the skies. Their dialogue is a testament to the importance of collaboration and communication in the complex world of aviation.
