| 摘要 |
The invention relates to a method for detecting and localising a fuel leakage in the engine of a multi-engine aircraft consisting in (a) determining a fuel consumption (L240, L244) for each aircraft engine, (b) in comparing the consumption of each engine with the other aircraft engines (38), (c) in determining the engine exhibiting the greater fuel consumption ratio (35, 45), in determining the excess consumption ratio (Q240, Q244) of said engine with respect to the other engines (38, 48), (e) in checking whether the excessive consumption is caused by a leakage (51 - 56) and (f) in triggering an alarm (59) if the step (e) is checked. A system for detecting and localising a fuel leakage in the engine of a multi-engine aircraft comprising an airborne computer for carrying out said method is also disclosed. |
