  1. While any terminals should ideally be 'bright' and certainly free of oxidation, cutting them back with a coarse abrasive is not always the best policy: First, if the terminal has an anti-oxidation plating, you may well cut that away. Second, if the resulting surface is scored, you are actually reducing the surface area that is in contact. Grease/petroleum jelly to reduce oxidation is an excellent idea. And with a wooden aircraft, I would be attaching all my terminals to a piece of metal, then attaching that to the aircraft. That is, I would not be relying on a screw, or bolt, that passed through wood, to maintain pressure on the terminals.
  2. M61a1 and I doubt it will make any difference, but I am an industrial automation engineer, design, build, maintain. Suggest you stick to what you know and I'll do the same. The only one ranting here is you. Give it a rest, mate.
  3. M61A1 I don't see post here which are screechy, or from people who appear to have "no understanding of the aircraft systems and no interest in understanding it". I suspect the real problem here is that others have minds of their own, and are failing to entirely embrace your expert views?
  4. Yes, I see that. I was referring to your earlier post and asking for your interpretation?
  5. You certainly seem hell-bent on attributing the blame to the aircrew, M61A1. Has it occurred to you that in the short space of time before the crew turned off the servos, the aircraft may have already been so far out of trim as to render it impossible for the crew to recover? And that their re-engagement of the servos could well have been a last-ditch effort to re-trim faster?
  6. My thoughts pretty much entirely. And it surprises me just a bit that folk here can continue to roll out their 'shoulds' and their theories, when the practical reality of the situation has been horribly demonstrated, twice over. Is anyone seriously suggesting all we need do is upskill them foreign pilots......and spin the wheel again???
  7. Come off it, M61A1. From what we now know of this MCAS, it is a lethally flawed system. In an aircraft that was sold as same-old, when it wasn't same-old at all. But you're right when you say the aircrew need to understand the system they're using. We can all agree on that, looking in the rearview mirror, eh?
  8. So if the '....nose down stabiliser trim...can be stopped and reversed by use of the electric stabilizer trim switches...' but '...do the Runaway Stabiliser NNC ensuring the Stab Trim Cutout switches are set to Cutout........' but 'Note..............Electric stabilizer trim can be used to neutralise control column pitch forces before moving Stab Trim Cutout switches to Cutout......' Really??????????????????
  9. M61A1 did we get a look at this "Safety Bulletin" and when it was isued???
  10. Well, first off, after the first crash, Boeing 'sat down' with SW Airlines pilots, and also the US pilot's union(?) or some such, and gave them some info on the MCAS system. If you look back in this thread, you will see that they were reported as being 'furious' that they had not been properly informed on the system. So, it sounds like essential extra info was delivered verbally to US pilots at that time. From there, it seems likely this info would have spread informally and in an uneven fashion. I see no mention of any formal transfer of information from Boeing to owners/operators until after the second crash, but possibly I missed that bit???
  11. First, I don't think much of the 'Oh they didn't do it right' attitude from some of these armchair 'experts'. And second, if they physically could not manually trim due to the pressures on the stab/elevator (and only one crew member would have been available for that if the other was fighting to get the nose up) then maybe re-engaging the trim servos was a last desperate effort to trim using the trim switches. Certainly there are 2 videos from different pilots in this thread so far suggesting that manually working the trim wheels could have been very hard, and harder by the moment with the speed rising: in one of the sim recordings the copilot makes a futile attempt to hand trim, and the pilot then gives him a hand.
  12. Oh...and the reflection would be from the underside of the aircraft, so while the silhouette would be much the same, the surfaces of it would be differently lit. Eg, while you can see the top of the wing and it is sunlit, the reflection would be of the underside of the wing, and so dark. Which it aint...............
