Those are good theories, but other articles have confirmed that the First Officer really did have 30,000+ hours experience. (I redacted their full names for privacy) I still have a lot of difficulty accepting someone with 40 years of flying in China has over 30k hours. The tempo of working 30-40 ye...Jump to post

Ok, I am a bit confused now. Who is right?

A big possibility. Do you think the Chinese government wants Americans in China telling the world that the cause of this crash was not a problem with an American product, but a problem with a Chinese pilot or maintenance staff?

Could it be a pilot suicide? Yes. Need to keep bias in check most flights in mainland China are not two crew. It is very common for Chinese mainland airlines even on domestic flights that they operate them with 3-4 cockpit crew.

Oh also, the Chinese Govt. grounding the 737 fleet rounds out to roughly 90% political, 10% safety. That's from my chair anyway.

Seriously what data would be available this soon after the crash that would indicate a need to ground the entire fleet? It screams of being a political/pr stunt.

It is to reduce the overall demand on the total system so hydraulics are prioritized for control surfaces. As the flaps/slats run the horizontal stab changes to maintain trim. So as flaps move slow, the horizontal stab moves slow, and there is still more than enough left over for the control surface...Jump to post

They shared maintenance and parts with CX, which have enough EDTO sectors to qualify to treat wholE 330 as an EDTO approved planes.

Regarding the maintenance perspective, I've heard that some airlines also choose to install ETOPS-certified parts on non-ETOPS aircraft so as to simplify maintenance procedures. IIRC Cathay Dragon, a subsidiary airline of Cathay Pacific, has non-ETOPS A330 installed ETOPS components as Cathay's A33...Jump to post
Any part of the chain broken and the aircraft will be downgraded and will require at least a verification flight before it can regain the status. So it's not something you can just slap on overnight to make an aircraft able to perform ETOPS flight. Most defects that downgrade an aircraft EDTO do no...Jump to post
Obviously there is no relief for a two person crew. But if you shift how far a two person crew can fly you need less 3 person crews ;) Once upon a time you could only get ETOPS180 after a year with no issues at ETOPS120. Now you can get beyond ETOPS180 from the get go. The whole point of this is to...Jump to post

Off the top of my head, ETOPS ready for the 737NG and MAX would include life-raft stowage compartments (two compartments on the ceiling in the middle of the passenger cabin) Lift rafts would be required when more the 100 nm or 30 min offshore, it’s not an EDTO requirement. You can be EDTO over land.Jump to post
Qatar's QCAA has now grounded the remainder of the A350 https://www.air101.co.uk/2022/03/qatar-civil-aviation-authority-qcaa.html Absolutely laughable, there would be half dozen just over a year old. The QCAA still has not informed the state of design the basis of their level 1 finding.Jump to post
Do you care to share what the 737 needs for ETOPS? Thanks! There is no single answer.

Basically asking if airplanes flying an IAP have to correct for cold temperatures if marked in the approach chart (and it is cold enough), does something similar apply to the flight levels if the temperature is much colder than usual (i.e., -100 deg F at FL270.

Please provide an ACAPS that demonstrates takeoff performance at 80C at sea level. I’d love to see it. Well obviously you have seen it.

Ok Zeke, whatever, have your own opinion but is the 77X not tailored, specifically to EK’s requirements (meaning capable of MTOW operation at max temps in Dubai in the summer?)

There were only two freighters in this competition: The A350F and 778F. Both have two engines.

I think it was clear from my post that the 77X was more or less over-engineered/given more thrust at hot/high for the ME3 appeal (basically more MTOW takeoff margin) not that the altitude/temperature at DXB is identical with ADD. I think some of that capability is a net minus for some operators wit...Jump to post

The 77X was basically engineered for hot/high specifically as I understand it (EK/ME3), so I’d guess the heaviest of the type (freighter) would have an advantage for Addis Ababa as well.

Hello All: I am curious as to what the process is with regards to installing and uninstalling ETOPS on an aircraft. Particularly a 737. Can it be done overnight or is it typically done in a check?
