Not in the least bit surprised that this lot would plow straight into a CB. This type of buffoonery is also common place amongst certain SE Asian carriers. It's not unusual for the flight crew to have the windscreens covered in enroute charts to provide shade, and zero visibility .
en route charts? how about pillows , blankets ? Recall coming back from crew rest once; approaching GT (Gilgit- "Hump Territory- i.e crossing the Southern Himalayas -(Grid Mora 29000ft or thereabouts ) on the China route for those readers who don't know .
Anyway, saw some weather deviation going on . Captain was busy doing stuff using the radar . However, the wise F/O was looking out of his (uncluttered) window ; (daylight flight) and giving good advice as to clear track through the CB line ; blue sky gaps in between the nasty stuff;
The captain insisted on following his radar track ( not bothering to look out of windscreen;( obstructed anyway) . Smooth ride through the weather , as it happened , but could have made life a lot easier for all by looking out the window . (remember the old saying ? " one peep is worth a thousand sweeps " .
But have to admit , no accurate warnings for CAT ( yes I know, you will quote CFP shear ratio numbers , but we have all seen high numbers forecast , and a smooth as silk ride ; and low numbers that have your teeth fillings suffering . The truth is , no one really knows ) .
More to the point in these days of RVSM is hitting wake turbulence from a heavy ( 380 , 747 or whatever) on the same track . Now , that can make your eyes water , even if you are in another heavy .
