19 Claims

1. A method for detecting a hardware configuration of an on-board device in an aircraft, capable of receiving as input a setpoint current (Ic), and of producing as output a response current (I), the method comprising the following steps:

a) Send, to the input of the on-board device, a setpoint current (Ic) at a given initial time (t₀);

b) Measure one or more response current values (I) at the output of the on-board device in a measurement-time interval defined between two instants (t₁, t₂) after the initial instant (t₀);

c) Infer the hardware configuration of the on-board device, doing so from the one or more measured response current values (I) and electrical current-response characteristics of the on-board device.
