Angle the radar up 10 degrees and I do t fly under red/magenta.
Wind direction and storm movement?
Published missed approach clear or not?
Alternate escape route that allows to stay in VMC conditions?
I’ve done visual approaches with an alternate missed approach coordinated with ATC prior to commencement.

Fly under the base of a red cell????

NO.

If you have doubts about an approach don’t do it; wait hold.
You cannot guarantee that the radar or even visual will detect a down-draft or outflow windshear.
If a Cb has been over the runway, allow 15 min for the runway to drain, otherwise use flooded runway landing performance.

Heed the advice of those who survived.

B2N2, gearlever,
Because you have done something before without event, does not change the inherent risk in the operation, thus never assuring success in the future.
The pre approach assessment is that of the risk in the plan depending on what is seen (or not seen) and judged as a justifiable course of action - what if this doesn’t work out.
It’s a judgement - yours and should not assume too much about anyone else’s involvement including the operational pressures such as a busy airport.

“During the approach the crew lost situational awareness, with their attention channelised, and the aircraft entered the storm cell with heavy rain after passing the MAP. The PIC did not arrest the excessive rate of descent, and flew the aircraft increasingly below the Glideslope.”

I’m not sure what you’re trying to say here.
If you approach it as something “you’ve done it many times before” then that attitude is wrong.
If you approach it as a challenge unique to that set of circumstances then you’re simply being a professional.
By doing this you develop a skill set.

B2N2,
Your appropriate professional view is only one of a range of outcomes dependent on how experiences in challenging situations are used. Risks assessed and adequately mitigated, the exposure reviewed and memorised, can contribute to professional expertise - professionalism.

Alternatives include inadequate risk assessment and mitigation, but with an acceptable outcome the exposure could be stored as a valuable lesson learnt (don’t do that again), or as an overconfident self-assessment of future ability. The latter is a powerful human bias - egocentric bias, also confirmation bias, choice supportive bias.

In an anonymous forum we cannot determine which of the outcomes is being related without further explanation, thus the reader could be adversely influenced if less adequate posts are taken at face value.
Question #1 represents an alternative approach, requesting information and explanation.
Statements of ‘I have done that before’ do not relate the actual situation to the experience gained, or the personal attitude of the poster - training capt or troll.
Biased memories can be hazardous because an unwary newbie could be adversely influenced.

Many posts in forums are opinion - ‘opinion is the lowest form of human knowledge’ Bill Bullard
In addition “I’m entitled to my opinion” is used to shelter beliefs that should have been abandoned. It becomes shorthand for “I can say or think whatever I like”. “You are not entitled to your opinion. You are only entitled to what you can argue for.” https://theconversation.com/no-youre...r-opinion-9978

My humble, argued, opinion.

So what’s your point?
Question was posted and I gave an answer and without any knowledge of my background and experience you’re calling that unsafe.

Our lot stipulate not to continue an approach if visibility reduces to 2000M or less in rain,when associated with presence of CB.
Slightly off the original post subject,but idea is to avoid likelihood of flooded runway associated with tropical downpour,and therefore,possibility of aquaplaning..
