We have one aircraft on our fleet that conducts an autothrottle self test when flap is selected for approach. The A/T light on the instrument panel will flash 2-3 times as part of this self test. Reference to this test used to be in our manuals however has for whatever reason been removed and I can find no reference to it any more.
Has anyone seen this in the FCOM and if so, could they cut/paste the text or PM me with it?
Cheers
