Douglas DC-4  Pilot's Handling Notes 
************************************

SUMMARY.

This DC-4 has four 1200hp Pratt & Whitney R-2000-11M2 Twin Wasp engines which are carburetted and highly supercharged to give rated power up to 5200 feet. 1450hp is available for take off (at sea level). The high speed blower provides 1100hp up to 15,000 feet. The constant speed propellers can be feathered. Automixture control is provided, but may be overidden.

WARNING - These engines suffer from harmonic vibration. Avoid use in the rpm ranges 1550 to 1800 and 2310 to 2510.

This aicraft is not pressurised. With passengers aboard operation above 12,000 feet should be restricted to 30 minutes per flight. For long haul military cargo flights with crew on oxygen normal C-54G cruise was at FL140.
