Fact is if you have combustion, you will get CO2 AND if you do use petrol derivative, you will get NOx. So it is all about managing how we do use combustion in engines. It’s a multi-prongs approach: behavior, efficiency, the fact that it is relevant or not in certain domain, identifying how we can do better usage of the resource, find alternatives and on the other end of the kill chain (of the ozone layer), how we can act to better this layer resilience (flight path and increased acute regulation for planes, space launches (next), reduction of methane (an easy, low cost that have a lower negative footprint on the industrial/agricultural chain but that pack a punch into the problem etc…

This is why the CO2 cap-and-trade system for CO2 made initially sense (the is the relevant and efficiency approach) until the prevention of NOx was mixed in it and blurred (just like the Diesel problem, it is not because you reject less CO2 that you are cleaner in term of much harmful rejects of NOx).

Yes, but english language defence media are not exactly a shining example of their accuracy in reporting Chinese military developments.

Didn’t I link a Chinese media written in English 😉

The South China Morning Post (SCMP) has been Hong Kong’s leading English-language newspaper ever since its first issue was published on 6 November 1903. Having kept our finger on the pulse of the local community’s development for more than 100 years, we have accumulated a treasure trove of information about every facet of Hong Kong.

A quick verbal statement on CCTV about J-20 “entering service” is not that significant in that regard given the accumulation of other events in J-20’s development else over the last few years.

It’s all over the specialized press today. I was not that much offtrack in final 😉

DRS chief executive Bill Lynn (Leonardo USA):

While the M-346 traces its lineage to the Russian Yak-130, Lynn argues today’s aircraft has evolved since the Finmeccanica and Yakovlev partnership.

“The M-346 has long since progressed and it’s quite a different design and different program,” he says. “I don’t think there’s much overlap. The airframe has been changed, the cockpit changed, the flight envelope is different.”

I don’t have the SA on this subject you might have. You’re probably right.

Note, they only say it is in service they do not say what degree of service (IOC etc), which obviously they do not ever release to us.

I imagine J-20 at this stage has entered service in the sense that the air force is using them in the IOT&E stage.

Yes. But it is somewhat noteworthy. If there was any risk at this level that the plane would be a failure, that won’t have happened yet.

@KGB: I can only invite you to stop the vodka for its known detrimental effect on your eyesight (color blind).

How will it impact the program?

Definitively, there seems to be a Rafale plague for those women head of state that discard the Fr favorite.

There is a thread (or maybe more than one) on plasma tech 😉
