The single AN-225 is still hauling freight, there are a few vlogs on YouTube of missions. Built in the Ukraine, airlifted total payload of 253820 kg

So its the AN-225 Mriya that is the biggest it terms of cargo hauling capacity (?) it was built initially to haul the Soviet Space Shuttle clone Buran around http://www.nieznanaukraina.pl/wp-content/foto/antonov-an-225/Antonov-An-225-%28Buran-II%29.jpg Not my pic but I saw this bad boy in this config at the Paris Air Show in 1989. Buran flew once and then the whole USSR thing went south.

Its a beautiful aircraft - Singapore flies them into ORT. Recently I took a look at the cockpit on the way out, a fantastic arrangement for the pilots a keyboard tray in front of them and a panaroma of flat screens. Very efficient as well apparently.

I doubt that was part of the equation, they had plenty of speed as it was. There was so much going on including the pilots stick shaker being triggered by the falsely high AOA indicator. The tunnel vision factor seems most likely, they were fighting the attitude and the trim system, speed was not kept in check. The auto-throttle system may or may not have been on as I understand it but either way that cant be blamed, what I have been told its generally set for a rate of climb after take off but because the aircraft was trimmed nose down the speed kept increasing - pity the code in the flight computer was so stupid and kept applying nose down trim despite the aircraft exceeding its max flying speed and the AOA indicators totally out of sync. I also read today on Aviation Week that the AOA also introduces a correction compensation for indicated airspeed, but that is small in comparison to what happened here - the aircraft was flying at 2x the normal speed in these circumstances. Also suggestions that it might have become more uncontrollable at this high speed of 500 kn - :"trans sonic" effects

It is in that preliminary report it states that the throttles were effective left (untouched) full forward, so that is a primary source of that info. It seems one of the crucial factors here (not saying errors because there could have been some circumstances) One of the rules of flying that linger in my memory from my flying days is Height with Power, Speed with Stick, so why did the aircraft not climb with the increased speed? because it was being trimmed nose down continually as I see it. So it just went faster and faster.... causing the massive pressure of that jack/lead screw that could not be over come by the FO using the trim wheel. Its not clear if the pilot tried to assist in the manual trimming. In one of Mentor Pilots youtube videos he deals with a horiz stab trim runaway procedure, the FO was on the whimpish side and the pilot had to help crank with the fold out handles. I wonder if that high speed simulated would also give associated high resistance on that control. Media reports are that the pilots followed all procedures as claimed by that Ethiopian official in that press conference but switching back on the electric trim goes against the proc (quoted in that report) that says the trim cutout switches must be left off for the remainder of the flight and that seems to have been the final straw because that meant the MCAS gave another session of fatal nose down trim... and besides that, not controlling the speed, I guess the Voice recorder will reveal the situation more.

Chris the same ou as back in the day? I think so .... that interaction with Nico was excellent. Quite honest account of The Wig moment ..but he did the right thing although he could have had 5 in the bag by now.

The preliminary report on the recent 737 Max disaster is here if you haven't seen it: http://www.ecaa.gov.et/documents/20435/0/Preliminary+Report+B737-800MAX+%2C(ET-AVJ).pdf My summary: Left AOL or feeder circuit fails shortly after take off MCAS tries to trim down Pilots try to trim up Speed keeps on increasing Trim Motor Cut Out switches enabled as per the procedure (which also calls for them to remain off for the duration of the flight) MCAS tries to trim down but does not result in change of horiz stabliser angle, consistent with the trim motors being switched off FO tries manual trim wheels but can't turn them (presumably because of the high speed causing high forces on the mechanism). Not indicated whether both tried Electric Trim is used again to try trim up (were the CO switches reversed?) MCAS then trims down because the motors were on and pitches the aircraft nose down 40deg and 500 knots into the ground. One possible explanation is that the electric trim switches were moved back up because they could not manually trim up. Apparently there are techniques for dealing with this in this state. Question I have is why the speed continued to increase to Vne (never exceed) "the N1 Reference remained about 94% and the throttles did not move." Does that means the throttle levers were left full taps? In my PPL training, although a distant past, I remember one thing, the first thing from dealing with an emergency "FLY the airplane" The tragic flaw in this airplane is the MCAS relying on only one AOA sensor. And the "AOA Disagree Indicator" being an option. Here is where Boeing is going to have a problem. Training videos I have seen is that the manual trim wheels need some muscle power to crank, Resistance will go up with the square of the speed.

Yes very impressive all rounder ... and having a successful business that generates lots of cash to facilitate these projects, only in the USA?

I am sure most of the computer aids make life easier for the pilots and flight safer, one can think of many systems for flight and engine management. ie the A350 has a system that will manage your landing speed and stop you at you desired exit ramp. From what I can see all the 727 Max's have MCAS, which in most situations is good safety feature, pushing the nose down by trimming the horizontal stabiliser when the aircraft pitches up close to stall BUT 1) Boeing didn't educate pilots enough about this new system, assuming they didn't have to worry or know about it because it was a safety feature, so certainly when things when wrong all it takes is flick of the two switches to disable the auto trim however if you don't know or understand what is trimming the aircraft nose down and spend your time trying to fight it, you are going to lose and the aircraft likely will crash. Certainly with Lion Air this is what happened. 2) This MCAS system is flawed is that it only used one of the AoA sensors, so if that fails you have a big problem with MCAS and need to turn off the autotrim pronto. Hard to believe their is no redundancy here although one finds it just about everywhere else. Probably due to cost saving. Using the 2nd AoA sensor was optional, I think South West took that option. It seems to be Boeing has something to answer for here, and the FAA.

Getflix does trick on the DNS, the traffic / data still comes via the normal routes unlike a VPN, so if you are getting buffering there is some other issue.

Check out Getflix smart DNS services as one option.

Most routers are powered by 12v DC with a center positive plug, that you can hook up directly to a battery terminals making sure you have polarities right, much more efficient that going through a UPS, just have to sort out a cable. The life of a Lead Acid battery is inversely proportional with Depth of Discharge, typically you don't want to go lower that 50% DoD at any time, so don't run the batteries down until they are flat, they won't last, its in the data sheets, so over spec your batteries taking this into consideration. Lithium Ion is a different story - I have just installed a 10.4 kWh pack that claims 5000 cycles and 80% DoD.

Just be aware that there are regulations / codes detailing how an external source should be hooked up to your supply. not only for compliance reasons but also for safety. Even if you do the genset installation and wiring to the main board, you should be getting a licensed Electrician in to do the final checks and connection.

I think he is Mech Eng hence his love of cars

This is the sad truth - the pandemic of stupidity that prevails. Policies that result in disaster and dysfunction, driven by so-called political policies but actually only foster a feeding trough for the corrupt selected "In" few (Blacks in cohorts with skelm Indians and Whites) - no room for talent, experience, resourcefulness, massive investments in education and ... honesty. The latest CEO of Eskom has zero zilch Engineering (yet alone Electrical) industry or otherwise experience, although he has proven to be a good executive elsewhere. Haven't had a look at the latest Eskom Board but eish Jhb City Power - very few there with any Elec Eng attributes, i would love to ask them individually if they know the difference between Voltage and Current, esp, Madame Comrade Chairperson, This dysfunctionality is the end game of this phucked up situation. And its not like 'they' will catch a wake up and employ the right people for job, instead they give out jobs like they give out houses, but the thing is one has to be able to do the job. With populist policies this is going to get worse.

I think we can expect to see more of him on the top step of the Grand Tour podiums - good climber, killah TT and a great team.

This is the kit I was looking at. https://www.propanecarbs.com/kits.html I have mains natural gas so this might be a good idea. I haven't worked out the running cost differences as yet but surely its cheaper than petrol although one won't be getting the rated power out the genset apparently since gas has a lower calorific value per unit volume or something like that.

They are fairy rugged, just get the cheapest. If there is no sparkplug its Diesel but you will be able to get a wiff of that from the fuel tank. Oil, Might be an idea to change the oil. SAE 10W 30 or equivalent is what is in my manual There is a gas conversion for these things going in the States, I am keen to try that.

There are certain generic China gensets that surface here under various brands, most of them of clones of Honda and Yamaha units. ie MacAfrica

Hei wenna maintenance is the white man's words! Power system / grid is running so maxed out that the flap of a butterflies wings in De Aar tips it over. Where to from here...ffs, what a stuff up. Interesting thing about that Cahora Bassa power line from Moz is that its DC, I think it was put in by Westinghouse and at the time and subsequently a bit controversial, I remember my Power Profs shaking their heads. But now high voltage DC power transmission are being rolled out more and more, I know in China there is some implementations there lately. Haven't revisite the theory but there must be a reason.
