The Redundant Independent Mechanical Starting System (RIMSS) is associated with which engine model?

• A. Allison Model 250C-KS4
• B. Pratt & Whitney JT9D
• C. General Electric LM2500
• D. Rolls-Royce RB211

Answer: (A)

RIMSS stands for Redundant Independent Mechanical Starting System, and it provides a completely mechanical way to start the engine, independent of the aircraft’s primary electrical or pneumatic start systems. This backup start method is integrated with the Allison Model 250C-KS4, making that engine the one associated with RIMSS. The other engines listed use different starting arrangements (air or electric starts managed by other systems) and do not feature RIMSS, so they’re not the correct association.
