Which unit illuminates various cockpit lamps?

• A. Lamp Display Unit - Illuminates various lamps around the cockpit
• B. Data Collector Unit - Collects information for EICAS
• C. Voice Control Unit - Manages spoken alerts
• D. Crew Alert System - Displays messages on a central panel

Answer: (A)

The key idea here is understanding how cockpit indicators are lit. The Lamp Display Unit is the component specifically tasked with driving the visual indicators around the cockpit—those small lamps and annunciators that illuminate to show system status, warnings, or advisories. It takes signals from the aircraft’s systems and turns on the appropriate lamps, sometimes also handling brightness and sequencing so pilots can quickly interpret the situation. Why this fits best: while other units handle related tasks—data collection for the engine/crew alerting system, generating spoken alerts, or displaying centralized messages—the job of turning on and managing the individual cockpit lamps lies with the Lamp Display Unit. The Data Collector Unit gathers information for the EICAS, the Voice Control Unit handles spoken alerts, and the Crew Alert System shows messages on a central panel; none of these are primarily responsible for lighting all the cockpit lamps around the cabin.
