Appologies for what may have been asked before. On airbus types that I have travelled on as SLF I have noticed the following. Just after push back and just after arriving at the gate after landing, there is a very loud noise like someone sawing an iron bar with a rusty saw!! or, more appropriately, a sound like an electric motor straining against a heavy clutch mechanism. Is this something to do with locking mechanisms on the baggage hold doors?? Its the only logical thing that I can think of. ( I've already identified the very heavy clunking sounds made by the braking mechanisms!!) I've been noticing this for year, but never really solved the problem!! Thanks in advance to any Airbus Drivers.
