    GCAS and more:

    “This technology is the stepping stone to increased combat capability via a fully capable combat autopilot that will be able to execute tactical manoeuvres to defeat inbound kinetic and non-kinetic threats, and maximise lethality through precise weapon employment,” says LeClair. “The future F-35 pilot is going to be a lethal battlefield manager with automated tools at his fingertips to ensure survivability and lethality.”

    Still no sign of the CVR to my knowledge

    Also

    The most hyped features of the 737 MAX compared with its predecessor, the 737NG, are more fuel-efficient engines.

    But as a result of the larger engines, which are placed higher and further forward of the wing, the jet’s balance changed. To address that, Boeing put in place more anti-stall protections, Leeham Co analyst Bjorn Fehrm said in an online post.

    An automated protection system called the Maneuvering Characteristics Augmentation System (MCAS) kicks in when the angle of attack is too high, when the plane’s nose is too elevated, threatening a stall.

    and

    Pilots can stop the automated response by pressing two buttons if the system behaves unexpectedly, the FAA says.

    That action is set out in a checklist used by Lion Air pilots for in-air troubleshooting, an instructor said. It is also required to be committed to memory by pilots.

    Personally I do not see the stick pusher as a totally new feature on the MAX but Reuters and the Unions (3 to date) seems to say it is.

    EDIT:

    Suspecting that the false AoA indication triggered the stick pusher erratically it sounds then normal that the crew requested an RTB as soon as the problem was identified (plane unflyable with presumed chaos in cabin). We should then focus our attention on what was the decision process that led them to not pursue an immediate landing.

    I am then very surprised that Unions and Experts does not raise this aspect of the story instead of targeting Boeing for something that does exist on one form or another since the 1950’s…

    no they buy less plane since a single plane can do way more. That’s why their operating cost per year will be only marginally superior (from 222 to 229M$/y – a ~3% and not 30% increase)

    Regarding ALIS, once again, there is a 30 days buffer time before a mandatory connection.

    Priceless Belgian humor:

    Journalist: Sait-on finalement pourquoi les Français ont choisi de déposer une proposition hors compétition?

    Col. Van Pee: Je ne sais pas. C’est assez incompréhensible

    ——————————-

    Q: Do we know at last why Frenches choose to make an offer outside the frame of the competition?

    Col. Van Pee: I don’t know. It’s impossible to understand.

    Great read overall. Give us an insight of what was really going-on underneath beyond the chimeric outcry in the press.

    I had in mind 3 years.

    Also:

    There is no sovereign guarantee that Dassault will meet its obligation of delivering the 36 Rafale fighter jets for which the country signed a Rs. 59,000-crore deal, the government admitted in Supreme Court today. What is there, government’s top law officer KK Venugopal told the court, was a “Letter of Comfort” from France – a written document that assures that an obligation will eventually be met.

    Sad news for India but a relatively good one for many French taxpayer here.

    But should we not be amazed by the quantity of inked paper filled by the French gov devoid of any meanings?! What about the much publicized Paris agreement? 😉

    Supreme court of India inquiry:

    The information [Attorney General KK Venugopal said] can’t be disclosed even under the Right to Information Act. “The price (revealed in parliament) was not of loaded aircraft. Secrecy is on weapon and avionics. The Air Force feels if it is disclosed, our adversaries will take benefit,”

    .

    interesting.
    I guess that someone in French parliament will raise the question….

    Also:

    […] Dassault has not yet submitted details of its offset partner, the government told the Supreme Court.

    “The vendor will inform the offset partner to us. So far there is no information on this,” said Additional Secretary Defence Apurva Chandra, to questions from the judges.

    What happen in Japan? Are the Bee constrained to fly with such weather restraint?

    Under the plan, Korea is expected to sell 30 KT-1 basic trainer jets and 20 T-50 advanced trainer jets, manufactured by Korea Aerospace Industries (KAI), to Spain. The European country also reportedly plans to sell four to six A400M Airbus transport planes to Korea as part of the aircraft exchange deal.

    […]
    Korea’s Defense Acquisition Program Administration (DAPA) denied the reported plan, saying “no discussion is underway” between Seoul and Madrid over the aircraft swap deal.

    “Spanish military and government authorities have yet to contact us via official routes over the deal,” an official from DAPA said Sunday. After reports over the possible swap deal surfaced in recent weeks, the defense procurement agency has contacted Spain to confirm whether the country is considering the deal, but the Spanish government denied the rumor, according to the official.

    The rumor came as a Spanish defense ministry reportedly plans to sell to other countries 13 of 27 A400M planes it has ordered from Airbus.

    Doesn’t sound anywhere credible… And certainly won’t boost the Korean industry in any manner if 50 of their KAI jets aren’t worth the price of 4 to 6 of those poorly designed under-performing not fit for military hangar queens.

    It’s also (but I might be wrong) a weird form of justification as the price discussed is just an assumption based on the overall cost of the “126” contract. There was not two different pricing – as far as we know – but a contract for the procurement of that number of planes. So as a basis of justification it is… baseless.

    Amazing news today (reuters): Lion Air crash scenario wasn’t covered in Boeing 737 MAX manual, pilot unions say

    Pilots of Boeing 737 MAX aircraft worldwide were not warned of a potentially dangerous feature suspected of playing a role in last month’s deadly Lion Air crash in Indonesia, investigators and pilots unions said.

    Either I don’t have the full picture, either I don’t get it at all but stick pusher have been fielded on bombers and fighter jets since the early generation of jets (before finding their way in some airliners); most of them flown by 19 years old Joe’s. Does those pilot union implies that the idea of counter acting the stick pusher in case of a false system alarm have to be taught in school for anyone to understand that? Are ppl landing on water when GPS are down? Have we seen anyone opening the side windows in flight because of a faulty speed indicator?

    I don’t get it.

    Wiki:

    Aircraft designers who install stick pushers recognize that there is the risk that a stick pusher may activate erroneously when not required to do so. The designer must make provision for the flight crew to deal with unwanted activation of a stick pusher. In some aircraft equipped with stick pushers, the stick pusher can be overpowered by the pilot. In other aircraft, the stick pusher system can be manually disabled by the pilot.

    When a manual is not correctly printed (some of them are even subcontracted), Pilots (and the hundred of us in back cabin that do grant them for their professionalism) are gonna crash?

    But let’s go back on Lion’s case:

    Pilots could stop this automated response [(the stick pusher action)] by pressing two buttons if the system behaved unexpectedly, but questions have been raised about how well prepared they were for such an automatic reaction and how much time they had to respond.
    Even though investigators say this problem was not covered in the operating manual, pilots did have access to a checklist designed to turn off errant systems when the plane started nosing downwards at the wrong time, said Soejono, a Lion Air instructor […].

    If this is another cultural thing like AF447, the proof is there that we have a systemic failure… in our pilot selection process.

    (you can read here for more)

    One day, if all that goes on, all plane’s documentation will be amended like this:

    *****************UNIVERSAL CHECK LIST ADD-ON PROCEDURE, YEAR 2057*************************

    – open startup sequence checklist
    – follow the procedure reading the list of actions line by line
    – at the end paragraph before setting full automation with the appropriate described action, open cockpit door
    – Yell for help (choose a sturdy and muscular passenger at your own convenience)
    – With your PiC (Passenger in Charge) go to the cabin door, open it and make sure the PiC understand closing procedure
    – go back in cockpit, press button firing-up full automation and wait for the bickering red light then turn back toward your selected passenger
    – smile at him/her (or upon your preference repeat your company welcome sentence)
    – Let him/her kick you out firmly of the plane
    – During your flight time down the tarmac, please, invite him/her politely to not forget to close back the cabin door.

    Enjoy your flight (the time it last).

    The T50A was built at a time when a trainer was envisioned for many different things. Why would you log hundred of thousand of flight hours – and pay for that – with an airframe braced to have an heavy radar in the nose, have the ability to carry bombs and designed to fit heavy avionic boxes when you don’t have to. You pay the extra weight, the extra complexity (maintenance) that you won’t ever use.
    When Northrop built the F-5a after the T-38, they understood that they had to keep their models segregated. They even had a family of trainer built out of the F-5A in parallel with their T-38. And money they made!

    LM and KAI went the other way around. It makes senses for customers fielding a relatively small feet of trainer but not for a service buying hundreds of them.

    Regarding the T-100, the KPPs where on the verge of their performance’s envelope.

    The mtiple changes of the helmet, jitter, gree glow, weight etc.) and that is a strong proponent of poor management

    It’s called an emerging technology. Without such “poor management” we will not even be flying braced wire fabrics covered airplane. The Wright brothers having been the first poor managers of aviation history.

    Rafale in India: detail of price could be released (submitted to court)

    But meanwhile, this (we mentioned this earlier):

    The offset arrangement does not involve the 36 jets that are part of the current deal […] with France safeguard[ing] government interests if there were contractual problems.

    !!!
    Dassault will have to start churning out lot of jets in no time… In India. I guess the IN delegation is walking with big smiles in the negotiation room.
    Although as we know since one month that Dassault intentions were to include MRO as an offset, I wonder if this has to be understood strictly (no Rafale involved = not even the maintenance cost).

    Also

    After the Indian Negotiation Team submitted its report […] on August 4, 2016, it was vetted by the finance and law ministries within 20 days and the Cabinet Committee on Security approved the deal on August 24, said the government.

    What an awkward set of risks from the Fr gov.*
