In the described system, when one engine on the right-hand side is running to provide power and AOG while the propeller is stopped, what mode is indicated?

In the described system, when one engine on the right-hand side is running to provide power and AOG while the propeller is stopped, what mode is indicated?

• A. Hotel Mode
• B. Standby Mode
• C. Normal Operation
• D. Safe Mode

Answer: (A)

The situation is signaling a ground/maintenance configuration where one engine is running to supply power while propulsion is not being used—the propeller is stopped. This matches Hotel Mode, which is used when the aircraft is on the ground (AOG) or undergoing maintenance and is using an engine to generate electrical/hydraulic power without engaging propulsion. Normal Operation would imply both power and propulsion are active for flight; Standby would indicate a backup or minimal-power state, and Safe Mode implies a fault or degraded safe condition. So Hotel Mode best describes a powered-on, propeller-stopped, ground-based setup.
