No fire extinguishing capability is provided for which compartment?

No fire extinguishing capability is provided for which compartment?

• A. Main Gearbox Compartment
• B. Engine Compartment
• C. Cockpit
• D. Fuselage

Answer: (A)

In this question, the idea is understanding how fire protection is applied differently across helicopter compartments. Some areas have fixed fire suppression systems installed, while others rely on detection, isolation, or manual firefighting rather than an automatic extinguisher. The main gearbox compartment does not have a fixed fire extinguishing capability. This is due to practical design factors: the gearbox space is tight and filled with oil and moving parts, and introducing a suppressant there could contaminate lubrication or damage bearings. Because of these constraints, a dedicated automatic extinguishing system isn’t installed in that compartment, unlike other areas where fixed suppression is provided.
