Section 3042 CLIMB A. AT 500 FEET (CONT'D) 5. Oil temperatures should be maintained at 165oF. by use of manually controlled oil cooler shutters. In the event of single engine emergency operation, the maximum permissible oil temperature for continuous operation is 220oF. During operation in extremely cold weather, the oil in the cooler core may congeal. This is generally preceded by a drop in oil temperature and followed by a rise in oil temperature. The tendency on the part of crew members is to open the cooler shutter when the rise occurs, but this action allows additional cooling air to pass through the core consequently slowing down the decongealing process.During operation in extremely cold weather, (below 0oF.)if no change in outside air temperature is observed, but the oil temperature starts to rise above normal (140 oF. - 170oF. normal oil temperature range) oil cooler shutters should be closed slightly from their original position. In a short period of time, the oil temperature should return to normal and cooler shutters should be adjusted to maintain correct temperatures. As there is no control for the oil coolers on R-1830-92 engines the only action that can be taken to reduce all temperatures is to increase the airspeed slightly. Normally oil temperatures are maintained within satisfactory limits by an automatic oil temperature control incorporated in the cooler. B. AT 1000 FEET 1. When Captains altimeter indicates 1000 feet above the terrain, it should be reset to correct barometric pressure for cruising. 2. Change can be made to cruising fuel tanks when 1000 feet of altitude has been reached, but fuel should be drawn from main tanks for at least 20 minutes after take-off to provide room for flow back from carburetor. 3 "No Smoking" sign may be turned off at 1000 feet for three minutes after take-off. "Fasten Seat Belt" sign may be turned off at this time or as soon as practicable. 1/15/46 DC-3 FLIGHT OPERATION
