There is no issue with flying through a typhoon. There is an issue with flying through a CB.
Typhoons are concentrated masses of CBs.
They are not the same. What appears to you on a conventional tilt based radar at 80 nm as yellow or red may not even paint on an RDR-4000. Your beam at 80 nm is around 24,000 ft, where the RDR-4000 will look at what is on your path. Have a look at that PowerPoint link above.
We have Digital Radar.
It's not your type. It's adequate, most of the time.
You are demonstrating a complete lack ATPL met knowledge here, cyclones, hurricanes, and typhoons whatever the local name for a tropical revolving storm are navigated through at altitude the world over.
Bull****.
As for those CX incidents, one was hail, the other two CAT. As far as I know none of them occoured on cloud, unlike CRK6704 which penitrated a CB.
Hail comes from CBs, right? The shields didn't work, surprise surprise!
If I don't know what EXACTLY happened to HKA6704 - what makes you believe YOU know.
Speculation and rumour, that's all.
