Abstract: A device for electrical distribution in an ignition system of an engine of an aircraft provided with a primary electrical supply and a secondary electrical supply, a primary igniter, and a secondary igniter, is provided with an electrical supply system adapted to supply at least one of the igniters alternately via one or the other of the electrical supplies. The electrical supply system is provided with a switch adapted to supply one of the igniters to which it is connected via one or the other of the electrical supplies. A detecting means detects if the igniter that is connected to the switch is also connected to the other electrical supply. The switch may have a relay supplied via one of the electrical supplies so that, in the event of defect of this supply, the igniter to which the switch is connected will be connected to the other electrical supply.

Abstract: A method for detecting and localizing a fuel leakage in the engine of a multi-engine aircraft consisting in determining a fuel consumption for each aircraft engine, in comparing the consumption of each engine with the other aircraft engines, in determining the engine exhibiting the greater fuel consumption ratio, in determining the excess consumption ratio of the aforementioned engine with respect to the other engines, in checking whether the excessive consumption is caused by a leakage and in triggering an alarm if the step is checked. A system for detecting and localizing a fuel leakage in the engine of a multi-engine aircraft including an airborne computer for carrying out the aforementioned method is also disclosed.

Abstract: The device for electrical distribution in an ignition system of an engine (100) of an aircraft provided with a primary electrical supply (105) and a secondary electrical supply (115), a primary igniter (110) and a secondary igniter (120) is provided with an electrical supply system (205, 225) adapted to supply at least one of the said igniters alternately via one or the other of the said electrical supplies. The electrical supply system is provided with a switch (205) adapted to supply the igniter to which it is connected via one or the other of the electrical supplies, and to simulate a defect of the electrical supply of these supplies. A detecting means makes it possible to detect if the igniter that is connected on the one hand to the switch is connected on the other hand to the other electrical supply.
