(3) If the airplane is parked more than two hours after it is refueled, drain the fuel tank sumps (AMM 12-11-03/301) before departure.
(a) If it is necessary, apply heat (hot air that is resistant to explosion) to the bottom of the wing in the area of the tank sumps.
S 653-151
(4) When you refuel the airplane, use these requirements:
(a) Make sure the fuel temperature is at least 6°F (3°C) above the fuel freeze point or -45.4°F (-43°C), whichever is higher. Use the ASTM method to determine the freeze point.
NOTE: The Fuel Quantity Indicator on the wing fuel station can
____ indicate slowly or not show numbers in extreme cold conditions. Use an external fuel flow meter to show the amount of fuel added to the airplane.
(b)
Use fuels that meet specification ASTM D1655; or
(c)
Use fuels that meet specification GOST 10227:
1) RT (PT, Russian spelling)
2) TS-1 (TC-1, Russian spelling)
(d)
Approved fuel additives are:
NOTE: Adding an anti-icing fuel additive may help in the
____
sumping of the fuel tanks.
1) Fuel Additive, specification GOST 8313, Fluid I (also known as Fluid E) a) Fluid I may be used at a mixture of no more than 0.15
percent by volume.
2) Fuel Additive, specification TU-6-10-1458, Fluid I-M (also known as Fluid E- Methanol). a) Fluid I-M may be used at a mixture of no more than 0.15
percent each, by volume.

(5) Do the Park the Airplane (Normal Parking) procedure (AMM 10-11-01/201).
S 423-071
(6) Install the engine inlet and exhaust covers as soon as possible after landing.
NOTE:____ Keep the engine covers in a warm location before you install them on the airplane. Covers that are cold or frozen may be difficult to install, and may freeze to the engine inlet and exhaust.
NOTE:____ At very low ambient air temperatures, the time for the engine oil to cool to -40°F (-40°C) can be greatly increased by the use of engine inlet and exhaust covers.
S 883-070
(7) Do one of the steps that follow to maintain the cabin temperature at or above 32°F (0°C): (a) Use the APU or a ground air source to run both ECS packs: 1) Do the Supply Conditioned Air to the Airplane procedure (AMM 21-00-00/201). 2) Use a heater, MARK I COLDBUSTER to heat the airplane through the ground air service connection panel, 193DL.
S 213-072
(8) Use the EICAS engine oil temperature indicator to monitor the engine oil temperature. (a) To view the oil temperature when the engines are not running, turn on the EEC ground test power.
