Starting propulsion turbine in automatic mode uses which system?

• A. Cams
• B. Nams
• C. Pams
• D. Eams

Answer: (A)

The key idea is that starting a propulsion turbine in automatic mode relies on an integrated automation system that handles the entire start sequence. This system coordinates the starter engagement, fuel flow, ignition, and protective interlocks, while watching turbine speed and other sensors. When the conditions are correct, it initiates the starter, brings in fuel, and then ramps the turbine up to operating speed on its own, handing control back to normal operation once stable. That centralized automation is what CAMS provides, so it’s the system used for automatic starts of the propulsion turbine.

The other acronyms don’t fit this function because they don’t represent the automated start sequencing and interlock control for the turbine. They may be associated with different monitoring or subsystems, but not the automatic start process itself.
