Claim:
1. A test apparatus, independent of an aircraft, for testing aircraft message trigger logic for the aircraft, comprising: a DFDAU (Digital Flight Data Acquisition Unit), which is configured to receive message trigger logic to be tested, wherein the message trigger logic is loaded onto the DFDAU: an input interface, which is configured to receive data of aircraft condition; and a simulation signal generator, which is connected to the input interface and configured to generate a simulation signal according to the data of aircraft condition, wherein a type and property of the simulation signal is identical to those of aircraft signals collected by aircraft sensors and data transmitted from other assemblies of aircraft condition: wherein, the DFDAU is further configured to receive the simulation signal and generate a message according to the message trigger logic to be tested based on the simulation signal; wherein the simulation signal generator comprises at least one of a discrete signal generation unit, a voltage signal generation unit, an analog signal generation unit or a bus signal generation unit; wherein the input interface is connected to at least one of the discrete signal generation unit, the voltage signal generation unit, the analog signal generation unit or the bus signal generation unit via a bus system; and a wiring extension device comprising a wiring board.
