I wasnāt going to post about todayās incident on this thread, given that itās being reported as turbulence. However, a line caught my eye in one of the reports:
"ā¦a bit of turbulence and suddenly the plane plunged,ā Source: Singapore Airlines flight live: British man, 73, dies during severe turbulence on London-Singapore flight - BBC News
Which reminded me of another incident, not that long ago on the same aircraft type (B777):
Could todayās incident be akin to the Latam flight in March this year, that was caused by a ātechnical incidentā (although this was a B787)?
Also really looking forward to my flight on a 777 in a couple of weeks nowā¦
Edit: including link to the FR24 playback of the flight. Incident occurred around 0748 UTC: 9V-SWM - Boeing 777-312(ER) - Singapore Airlines - Flightradar24
Cross-Atlantic - lots of jet streams!
You can have look at relevant charts, you might need to look up for the decode for the met symbols for wind strength / turbulence.
its behind a pay wallā¦=(
One slightly more āobviousā comment - but it was linked to more detail on my original write-up.
A few more scattered around. 
I always have my seat bet done up when flying. It only comes off when it is time for a visit to the WC.
Safest thing to do - looking at the numbr of injured people on the flight, itās probably safe to say that for those who were in their seat, they didnāt!
For a day time long haul flight as a pax, I will always look at the aviation turbulence forecast & correlate it with the expected route / approximate timings to hit any turbulence areas. Been more than several times when Iāve "planned " my WC break on my look at the forecast, & have been back in seat (all strapped in) about 10-15 mins before moderate turbulence was encountered - no prior warning / anticipation from the flight deck by putting on the seat belt signs / giving a PA to pax. Thatās not very professional, especially as the āoperational flight planā should show predicted wind shear figures. No good for the cabin crew either, as they might be out on a service, with heavy lumps of metal (trollies) that canāt be secured when in the cabin.
Not so hot on looking at forecast for any red-eye flights, as hopefully Iām watching a movie or trying to sleep!
When operating on long flights, especially over the Atlantic or other āhot spotsā for turbulence (jet stream or mountain wave related), we would always listen out (or ask) for āride reportsā from aircraft ahead, & if necessary anticipate the turbulence by flying at best turbulence speed (halfway between max & min buffet speeds), pre-warning flight attendant / pax & plonking on the seat belt sign.
That was an interesting read/look, thanks for sharing - I actually wasnāt aware of the volcanic eruption south of Lima, although I donāt think my flight path goes particularly close to it anyhow.
I canāt quite recall if Iām heading over in the wet or dry season for South American (although where Iām actually going to be based is desert anyhow), so could be fun heading over the top of the Amazon Rainforest if it is wet season, given Iāll be over that area around midday local time.
