    Air Senegal is leasing the HiFly A380. Some problem with their new A330neo.

    What is the advantage of buying a small fleet of F/A-18F Block III instead of EA-18G Block II ?

    Well the approach to quality assurance in a Boeing plant in South Carolina might fall in that category one of these days. The mechanics are increasingly required to inspect their own work --now apparently up to about 90% of the assembly process-- in production of new 787 Dreamliner aircraft.

    Many errors are either not found or not reported in timely fashion and so not addressed until late in the final QA process. That has ended up increasing, not reducing the total number of days it takes from start of assembly to day of first flight even if the planes are assembled faster. And, the plant is subject in 2019-20 to 100 more reassignments from inspection crews to other tasks.

    I read that you can pay a supplement to order F/A-18F's wired to convert them later into Growlers, and that you can convert Growlers into F/A-18F's.

    Even the 787 has some faults, though these have been addressed over time. The issue of the 737 Max is bizarre. Unheard of in the industry. Thankfully, you can almost always see what equipment is used on a flight booking before you book it. Though Boeing had laid off 200 employees 2 years ago at their North Charleston plants. This was after Carrier went back on their word and long after Trump's deal.

    I divested about 95% of the stock I held in Boeing this last summer. I bought way back when it was dirt cheap. I figured this is as good as it's going to get and to invest in better things. I have a feeling Boeing was banking on Trump not blowing up the Iran deal since Iran was to buy $20B worth of planes from Boeing alone. Around 19B from Airbus, too. That would have been some great cash injection over a controlled timeline.

    My best stock choices seem to have been in tech sans Apple because I had a dumb-dumb moment over a decade ago.

    I think Boeing got really sloppy with the 737Max. Poor design(1 sensor for such a vital system!?!?), poor testing, poor certification. I am very wary of such 'smart' tech going into products without manual override switches for the human operators.

    If anyone's interested, here's a docco I found pretty informative...

    Typical fly by wire aircraft rely on triplicate for vital functions so this is surprising and alarming. I have not yet watched the video.

    You mean the “Bombardier C-Series?” ;);););)

    True, however Boeing could have avoided the single sensor issue simply by implementation of MCAS exactly as in the KC-46. MCAS in the KC-46 has always relied on input from both AoA sensors. MCAS in the KC-46 was a further development of the system from the Max. To not implement the changes on the Max was an extremely flawed process, and Boeing should be held responsible.

    OTOH, if the crew on ET 309 had been monitoring their airspeed and recognized that AT was engaged at 94% thrust they would have saved the aircraft IMO.

    In no way am I minimizing the CRM demands during the 6 min flight. However, if one was flying and the other was running the lists the AT should have been disengaged. The aircraft could have been manually trimmed at 230kts. Because of the AT they were at 340kts and trying to manual trim.

    Turned the stab trims back on against procedure and at 340kts the MCAS pitch down was unrecoverable.

    I’m just sayin every accident is a chain of events. :apple:

    I prefer C-Series. I also like Embraer being Embraer.

    The oldest Lufthansa A320 was retired yesterday and flew over the Hamburg plant.

    Today is the 50th anniversary of the launch of Airbus.

    Yesterday marked the 50th anniversary of Korean Air taking delivery of their first Boeing. A 707. It was noted with the delivery of their 200th Boeing a 773-ER. :apple:

    Are you making a comparison or do these aircraft use those as their central computers? I suspect the former (I hope). :p

    The latest versions (F-16V is unspecified but only twice as fast as previously). Gripen E is also unknown.

    I think there's no more 68k in the Eurofighter since Tranche 2.

    I think a better way of seeing how expensive a plane is would be adjusted price per tonne (fully loaded).

    One would have to factor the material used in the construction. Materials are more of a cost factor than simply weight. That being said for commercial aircraft, say the recent increase in MTOW by 6T on the 787-10, it's additional weight gained through structural improvement does generate a price increase. One could argue the customer is simply paying for the additional performance as well. :apple:
