Test device and method for aircraft combustible liquid discharge test

A test device for performing an aircraft combustible liquid discharge test, comprising: a liquid reservoir comprising a storage space for storing a test liquid and comprising a reservoir outlet for the test liquid to exit; a liquid pump in fluid communication with the storage space to urge the test liquid out of the liquid reservoir via the reservoir outlet; a discharge line in fluid communication with the reservoir outlet for the discharged test liquid to flow therethrough; and a nozzle assembly connected to the other end of the discharge line opposite to the end close to the reservoir outlet so that the discharged test liquid is discharged therefrom, and a discharge line liquid level sensing device disposed along the discharge line and configured to indicate whether the test liquid in the discharge line reaches a predetermined amount. The invention also relates to a method for carrying out the airplane combustible liquid discharge test by using the device. By means of the test device, accurate control over
