back to the discussion on the fire test procedure after the fire QRH items have been actioned, can people please tell me if you would test with fault/inop or ovht/fire switch??????? and what are the indications you should be looking for on the overheat/fire protection panel relating to the 737-300/900 type. I am a bit confused about this point that one of the posters is talking about, as of now no one has told has ever told me about this for a FAR 25 style aircraft??
