Ethiopian 737 Max 8 crash and Fallout

[jase05]

Virgin refusing to comment other than still planning to take delivery, while other airlines and countries ground the aircraft.

At the end of the day CASA haven’t certified it for AU yet right...?

MI and FJ both operate them in Australia already

Why has there been no crashes or reports of this issue by pilots in the US where the majority of Max's are located? I suggest weather (humidity) as both Indonesia and Ethiopia are near the equator.

Lots of the USA is pretty humid too. Most likely pure random chance. I would expect that we'd be hearing about it, if it was happening to US pilots, and they were saving the day.

Could a Qantas, United, Virgin, BA pilot etc save the plane in a extremely overloaded scenario at low altitude?

Who knows? All airlines have pilots both good and not so good. And pilots have days that are better than others.

The pilot is listed as having 8000 hours of flight time, the co-pilot just 200 hours. Could this affect the crew's ability, as a unit, to deal with an emergency of this nature? (That is, would the captain be able to fully rely on the copilot or would they be essentially handling this solo... and could that make a difference?)

In many ways both of these people are low hour. 8,000 is not a huge number, and 200 is barely a blip. QF does not have FOs with such low hours, and it also restricts inexperienced pilots flying together. New captains get old FOs...

Be careful here. Technically at 7657ft 18ºc is not cool at all. In fact it's 18º hotter than ISA! At 7650ft ISA is around 0ºc.

I've never operated at that level, but even 5,000' makes a lot of difference. But, I don't see performance as being a likely player here.

Yes, but I don't think that CASA will have certified them. That's up to their own regulatory bodies.

Ah Thank you - this was raised in the pilot thread “temperature lapse rate” 2celcius per 1000ft

So 15+18 equivalent to 33C at sea level?

Yes, but that's not the same as the density altitude.

All you never wanted to know is here...Effects of Pressure & Density Altitude on Aircraft Performance

 

[drron]

I believe only 80 of the 350 737 Maxs delivered have gone to the USA.There was a link that Boeing put out about deliveries but no longer working.

 

[Quickstatus]

Yes, but that's not the same as the density altitude.

All you never wanted to know is here...Effects of Pressure & Density Altitude on Aircraft Performance

Yes understood. Air density related to temperature, altitude, air pressure and humidity and ISA assumes standard QNH

Your point being.....? They are foreign airlines...

Unverified eyewitness account of fire from rear of ET302 prior to crash.

Can a compressor stall give this appearance?

Absolutely. Looks like a massive flame coming from the rear.

Has there been any reports of them finding the various black boxes yet?

 

[Berlin]

Has there been any reports of them finding the various black boxes yet?

CNN just reported that both black boxes have been found. That was quick!

 

[Must...Fly!]

Has there been any reports of them finding the various black boxes yet?

Yes not long ago, state media reported it in Ethiopia.

 

[Berlin]

The airline has just confirmed via Twitter: Ethiopian Airlines on Twitter

 

[Must...Fly!]

Absolutely. Looks like a massive flame coming from the rear. View attachment 156844

What is the performance implication at that altitude, if I may ask?

 

[Quickstatus]

Compressor stalls can be due to:

Bird strike or somexengine failure
Certain Flight manoeuvres disrupting airflow within the engine - eg aircraft falling from the sky or velocities beyond design limits?

Anything else?

I thought it would be relatively quick - they probably only had to search an area 100 x 100 metres unfortunately

 

[flyer89]

I don’t put much credence in eyewitness testimony as it is so often wrong but if flames were observed that would be a rather interesting spanner in the works.

True- not flying over water in this case. I got far too used to these endless searches on the bed of the ocean!
