Which communication technique should be avoided for effective air traffic control?

When considering effective air traffic control communication techniques, speaking too slowly is crucial to avoid. In the context of air traffic control, information must be relayed efficiently and under potentially high-stress conditions. A slow pace can lead to delays in understanding critical instructions or information, which can compromise both safety and operational efficiency. Timely communication is essential for maintaining the flow of air traffic and ensuring that pilots comprehend instructions without unnecessary pauses or confusion.

Conversely, talking into the microphone properly, speaking with confidence, and maintaining a normal conversation tone are conducive to clear and effective communication. Using a confident tone instills certainty and authority, while a normal conversation tone helps to establish rapport and aids in comprehension. Thus, avoiding a slow speaking pace is vital for success in air traffic control communications.
