What does CDTC stand for?

Controlled Descent Through Clouds refers to a specific maneuver that involves an aircraft safely descending while navigating through cloud cover. This process is particularly important for maintaining visual and instrument flight rules and ensuring that pilots have adequate control and situational awareness during such conditions.

When flying in cloud, maintaining control and ensuring a safe descent is critical because visibility is often severely reduced, and pilots rely heavily on instruments to navigate and avoid obstructions. Controlled Descent Through Clouds indicates a training and procedural protocol to manage aircraft descent effectively in these challenging environments.

The other options may suggest methods of data transmission or taxi procedures, but they do not pertain directly to the safe operational practices associated with descending through clouds. Thus, the focus on controlled descent ensures the safety and efficacy of flight operations, making this the correct answer.
