A RSVR 1 LOW caution indicates which reservoir condition?

• A. The pump 1 is failed
• B. The main rotor speed is low
• C. The tail rotor cable failed
• D. The fluid in reservoir 1 is low

Answer: (D)

Reservoir level monitoring is about keeping enough hydraulic fluid to power the flight controls. RSVR 1 LOW specifically means the fluid in reservoir 1 is low. This warning comes from a level sensor in that reservoir and signals you to check the hydraulic reservoir, look for leaks, and top up with the approved fluid if needed. It’s not indicating a pump failure, rotor speed issue, or tail rotor cable problem—those would produce different alerts. The key idea is that this caution tells you the hydraulic reservoir 1 is low, which could impair hydraulic power for the flight controls if not addressed.
