Abstract
The invention relates to a method (E) for detecting the ignition of a turbine engine combustion chamber, the method (E) comprising the steps of: receiving (E) a first measurement of the exhaust gas temperature downstream from the combustion chamber, before an attempt to ignite said combustion chamber; receiving (E) a temperature threshold; receiving (E) a secondary detection criterion; updating (E) the received temperature threshold as a function of the secondary detection criterion received; receiving (E) a second measurement of the exhaust gas temperature, after the attempt to ignite the combustion chamber; comparing (E) the updated temperature threshold with the difference between the first and second exhaust gas temperature measurements; and determining (E) the state of ignition of the combustion chamber.
