@TamithaSkov @e_philalethes If one was being skeptical, this is entirely plausible
English
@BenClewer @e_philalethes Here is a plausible, if ridiculous idea: the GLE did cause unresolved issues, but not any that the public would believe justified the recall, so they pointed to an unrelated incident in which people got injured so they could pull the planes out of service with no questions asked!
English
The problem is the incident they cite as the reason for the required fix, namely the Jet Blue altitude drop on October 30. On that day, space weather was completely quiet. No solar storms, no radiation storms, and no radio blackouts from solar flares either. Was it just a chance GCR secondary or a delayed response to an earlier single event effect in the avionics?

Intense radiation from solar storms jeopardize aircrafts, big recall of Airbus ordered to enable fix. Other aircraft makers may follow suit “Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls,” Airbus said in a statement. US US3 min read Thousands of passenger planes need to be fixed to avoid pilots losing control during a solar storm By Aaron Cooper Updated 3 hr ago  Thousands of passenger planes need to be fixed ... 2:33 Thousands of the most popular passenger aircraft in the world need immediate maintenance to protect from a problem that injured passengers and caused an emergency landing last month. Airbus found intense solar storms, like solar flares, could cause pilots to lose control of the Airbus A320 series of planes, including A319, A320, and A321s. About 6,000 of the single-aisle planes, which are the bestselling passenger aircraft in the world, need the repairs. “Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls,” Airbus said in a statement. On October 30, JetBlue Flight 1230 - an A320 - was flying from Cancun, Mexico, to Newark, New Jersey when it suddenly dove down in altitude. The pilots made an emergency landing in Tampa, Florida, where about 15 people were taken to the hospital. Airbus investigated the incident and on Friday told airlines in an “Alert Operators Transmission” that the fix was needed. The company believes it is the only time this specific problem has happened, but says it “proactively worked with aviation authorities… keeping safety as our number one and overriding priority.” The Airbus A320 series has what’s called fly-by-wire controls: physical movements from the pilot run through computers which, in turn, adjust the plane’s control surfaces. An airworthiness directive from the European Union requires airlines to make the repairs before the planes can carry passengers again. From: reuters.com/business/aeros…

@e_philalethes @TamithaSkov This is true, but there might be more data from the recent event which has forced them to hurry up a fix. However, this is of course speculation
English
@BenClewer @TamithaSkov Problem with that is that, while as has been speculated it might have been the accumulation of errors before the actual incident, the notable GLE recently happened almost 2 weeks after the incident in question. But when I first read the headlines that was my first thought too.

@BenClewer Thank you, great site. I'll have to save that and reference for future flights.

I wonder what intense solar radiation does to our brain cells up there? Sort of explains a lot about most of my pilot friends…ok, and myself.

“Analysis... has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls. Airbus... identified a significant number of A320 Family aircraft currently in-service... may be impacted.” Currently ~3,000 airborne A320 family aircraft.

@CaptBob_Nomadic A typical transatlantic flight is offered touted as the equivalent of a chest x-ray.
We have a prototype webpage at spaceweather.surrey.ac.uk/maire-s_nowcas… where you can see the modelled dose in real-time. For reference, 0.1-0.2uSv/hr is the ground rate in the UK.
English
@CaptBob_Nomadic Typical rates at cruising altitude are 10-20x on the ground and the particles are such high energy that the fuselage doesn't shield against them.
The largest radiation storm measured was a 50x increase at ground level, so altitude would have been far worse.

@Flying_Abi I'll try again, this paper is an excellent piece to read

@SimonCalder Our research group at Surrey Uni has been warning about potential issues like this. In fact there was a recent solar radiation storm which has likely exacerbated the response to the issue seen on the 30th Oct
English
Thousands of Airbus A320 series aircraft may be temporarily grounded due to solar radiation fears.
Millions booked to fly on the jet could find flights cancelled while urgent modifications are made.
Assume yours will go ahead unless airline says otherwise.

@BBCBreaking Our research group at @SpaceAtSurrey have been warning about the impacts of radiation on avionics for decades. We have data to suggest memory systems could be highly susceptible. There was a recent radiation storm too 2 weeks ago

@karen_aplin @metoffice @UniOfSurrey @KNMI No they didn't claim any more than that. The programme specifically for space weather is new
English
@BenClewer @metoffice @UniOfSurrey @KNMI Fair enough - first neutron profile during GLE. But the @metoffice claimed rather more than that!
English
World-first radiation data through Earth’s lower atmosphere has been collected in a collaboration between the Met Office, @UniOfSurrey and @KNMI.

@williemossop @metoffice @UniOfSurrey @KNMI This was the first time ever that radiation data has been collected across a spectrum of altitudes during a GLE. The method is not new, but the data from this event was
English
@metoffice @UniOfSurrey @KNMI Hardly that innovative.
Radiosondes have been around for a while now.
Just add another sensor to the package & launch it.
What would be innovative is if you reopened the Stornoway & Shanwell upper air stations.

@karen_aplin @metoffice @UniOfSurrey @KNMI This was the first time data was collected at the full range of altitudes during a GLE. Yes balloons and radiosondes have been used for years, but not with specialised neutron sensors during a solar radiation storm
English
@metoffice @UniOfSurrey @KNMI This claim is highly doubtful. Historical record is described here (spoiler alert: actual world first on this was nearly 100 years ago) hgss.copernicus.org/articles/5/175…
