What is a Mode C transponder used for?

• A. To record flight data
• B. To broadcast altitude and identification code
• C. For navigation assistance
• D. To enhance communication with ground control

Answer: (B)

A Mode C transponder is primarily used to broadcast an aircraft's altitude and its identification code. The transponder sends out a signal containing this information, which is received by air traffic control radar systems and other aircraft equipped to receive transponder signals. This allows for better tracking and separation of aircraft in controlled airspace, enhancing overall safety. The transponder's ability to provide altitude information, along with the aircraft's unique identification code, helps air traffic controllers maintain situational awareness and ensures effective management of traffic in busy airspace. This capability is crucial for avoiding mid-air collisions and for the efficient flow of air traffic. While recording flight data, providing navigation assistance, and enhancing communication with ground control are essential functions within aviation, these functions are not the primary role of a Mode C transponder. Instead, the focus of a Mode C transponder is specifically on altitude reporting and identification, which support the safe operation of aircraft in controlled environments.
