Which of the following is NOT a required sensor for ECDIS operation?

• A. Speed
• B. Heading
• C. Radar
• D. Position

Answer: (C)

In the context of ECDIS operation, required sensors primarily include those that provide essential data about the vessel's movement and location. The primary sensors include the speed sensor, which measures the ship's velocity through the water, the heading sensor, which provides the vessel's direction of travel, and the positioning sensor, such as GPS, which determines the vessel's exact location. Radar, while a valuable tool for navigation and situational awareness, is not a fundamental requirement for ECDIS operation. ECDIS can function and display critical navigational information using just the necessary position, speed, and heading data, without relying on radar input. Therefore, radar is not considered a required sensor for the basic operational capabilities of ECDIS, making it the correct choice in this scenario.
