I'll help you there, before you go back and climb under the rock you came from FGD. You're wrong I'm afraid (& very wrong for supporting the git GT)
GT on CNN said the aircraft landed upside down on the water... in another interview he said it broke up in flight due to the indication of a unclothed body being found floating... I won't go on.
Radars and the facts: The A320 IS equipped with an advanced radar able to detect such CB's and turbulence. Quote from the manual:
...RDR-4B advanced weather radar and our new IntuVue family of 3-D volumetric weather radars are the most advanced weather surveillance equipment in the industry. For the A320 family, the RDR-4000 model of the IntuVue family allows pilots to detect and reroute around storms sooner for improved safety and route efficiency. Its advanced turbulence detection and windshear capability has demonstrated over a 50% reduction in turbulence encounters.
Question here is were they utilising it correctly?
Now how do we know major CBs were a factor?
Just by looking at the repeated and multiple weather replays run by BBC/CNN et all, of the time in question. There were MAJOR reds and magentas (=Severe to Intense)! IF you have any idea or experience of the monsoon trough (ITCZ) you know that to penetrate such moisture is stupid and you can not out-climb any CB's, so divert as much as is needed. It's the only way. This vision together with personal experiences, is what qualifies many of us to make such a comment as ARM did. Together with Havoc's comment above regarding frozen probes & Alpha vanes, it scratches on the surface of further possibilities.
So ARM it seems would be correct then.
P.S. Sidetrack but no aircraft can automatically fly or is rated to fly an "RA" yet, apart from A380/350 and 787. Company policies may also limit this use of automation (Interesting Cathay incident on this, by the way).
P.P.S. You think it's rubbish, that many of us pilots can do a better job than GT? Pull yuh head out, please. Many of us on here have done so in various capacities already, well before he started getting his noggen on the idiot box!
(edited and toned down once off my soap box)
Happy Landings.
