What is the RPM used for Cruise/Descent (max cruise)?

During cruise you select an RPM that keeps the engine within its prescribed operating envelope while giving good efficiency. The published max cruise setting for this airplane is 1700 RPM, which balances adequate airspeed with keeping cylinder head temperatures, torque, and other limits in check. Using a lower setting like 1600 or 1650 would still be safe but reduces efficiency and speed. A higher setting, such as 1800, would push beyond the intended max cruise limit and could approach the upper limit of the propeller/engine envelope. So 1700 RPM is the best choice for max cruise.
