FIELD: transport. ^ SUBSTANCE: invention relates to method of testing aircraft oxygen feed system control device 30. Proposed device comprises one or several sensor signal inputs to receive signals corresponding to one or more states of oxygen feed gas system and may generate one or more control signals to exercise control over one or more oxygen feed system state indicators proceeding from said one or more signals. Proposed method comprises the following stages: test device (40, 42, 44, 46) including test signal switch module 40 with one or more test signal feed outputs 62. Note here that said module comprises switches (54, 56, 58) to switch ON/OFF test signals, connects module test signal outputs to control device sensor signal inputs 30; feeds test signal from at least one module test signal output 62 to at least one signal input of the sensor. Switches (54, 56, 58) of module 40 are actuated to change the state one test signals between "ON" and "OFF" stages to control the readings of at least one indicator 36 of oxygen feed system state. ^ EFFECT: higher efficiency of testing. ^ 10 cl, 3 dwg |
