How should an aircraft identify itself when initiating a radio contact?

• A. By using its assigned call sign (usually the registration) at the start of the transmission
• B. By reporting only the aircraft's type and color
• C. By transmitting an emergency signal first
• D. By sending its position before identifying

Answer: (A)

When starting a radio contact, identify the aircraft with its assigned call sign right at the beginning. This immediate identification gives air traffic controllers a precise, unique reference, ensuring clear communication and proper routing, especially in busy airspace. The call sign is usually the aircraft’s registration, and putting it first avoids confusion about who is speaking before any other information is exchanged. Reporting only the type and color doesn’t establish a unique identity, an emergency signal is reserved for distress situations, and sending position before identifying would delay proper recognition and could lead to miscommunication.
