The actual specific freeze point of the fuel load will then be placed in the aircraft logbook prior to departure. The crew will take the specific fuel freeze value, round it up to the next whole number, and add 3 to that number and place that number in the FMC PERF INIT page at LSK 3R. For example, - 46.7C freeze temperature from the logbook, rounded up to -46 C + 3C = -43 C in the FMC. This will establish a new minimum operating temperature for the fuel loaded on the aircraft. The fuel freeze test will be accomplished at Departure airfield for all polar flights and segments especially during winters. The routing for the return segment (non-polar), and the fact that the aircraft will be loaded with Jet A-1 (minimum freeze value of -47 C), negate the need for the fuel freeze testing. In the event that the aircraft is fueled using Issue I 28.08.2007 Rev. 0 PAGE 6-2 FLIGHT DECK PREPARATION CHAPTER 6 TS-1 (which is found in Russia and is an approved fuel), no freeze testing will be done, given its minimum freeze point of -50 C. 6.3 FMC Preflight |
