What does DFC stand for?

• A. Direct, fluent, concise
• B. Decisive, firm, clear
• C. Dynamic, fast, controlled
• D. Decisive, friendly, courteous

Answer: (B)

DFC is about how to communicate, especially in demanding or high-workload moments: it stands for being decisive, firm, and clear. Being decisive means giving a concrete instruction or making a clear decision without hesitation, so others know exactly what is expected. Being firm reinforces authority and ensures crew and others follow the instruction without delay. Being clear ensures the message is unambiguous—using precise language, specifying what needs to be done, who should do it, and by when. This combination helps prevent misinterpretation and speeds safe, coordinated actions in the cockpit or with air traffic control. The other options don’t capture all three essential elements together: friendliness or fluency without authority isn’t enough, and terms like direct, fast, or dynamic miss the explicit emphasis on firmness and unambiguity.
