How should engine power settings for different flight phases be determined in the DA20-C1 without relying on exact numbers?

• A. Follow fixed power settings from an external source not in POH
• B. Apply engine power based on temperature only
• C. Set power by trial and error in flight
• D. Use the POH guidance for phase-specific power settings, aim for smooth transitions, and maintain recommended airspeed and attitude for each phase

Answer: (D)

In the DA20-C1, the appropriate engine power for each phase of flight comes from the pilot’s operating handbook. The POH provides phase-specific guidance that matches the airplane’s performance needs, engine limits, and aerodynamic behavior for takeoff, climb, cruise, descent, and approach. Following these recommendations helps you reach and maintain the target airspeed and the correct attitude for every phase, which promotes predictable handling, efficient operation, and a safe stall margin. Transitions between phases should be smooth, with small, coordinated adjustments rather than abrupt changes, so the airplane remains stable and comfortable to fly. Using anything other than the POH guidance—like fixed numbers from an external source not in the POH, or relying on temperature alone—can misrepresent how the aircraft actually performs in your weight, density altitude, and configuration. Trial-and-error in flight is unsafe and wastes time, because it risks exceeding limits or compromising control.
