it is easy to tell those who fly through rain regularly and those that don’t. Green on a wx radar just means 4 mm/ hr or less rain, yellow between 4 and 12 mm/hr and red > 12 mm/hr. 12 mm of rain per hour in the tropics is not unusual and does not indicate a TS alone.
Pilots need to be able to use tilt, gain and mode. They need to effectively use manual gain, Wx Turb, and tilt.
Boeing and Airbus have no technical objection to flying through rain or landing when it’s raining.
