ATPL HUF Question- Heavy Rain
Hi guys,
Just a quick question I'm having a little trouble deciphering in my human factors study.
In low visibility, ie heavy rain, snow, fog etc. The pilot will believe that he is too low on the approach.
However, in heavy rain, the windscreen itself is further refracted by the rain (up to 5º estimated). This gives the pilot the perception of being too high on the approach.
My question is, what actually happens in the scenario of flying an approach in heavy rain? One would have to assume that low visibility is a given in nearly all scenarios involving heavy rain, which makes it even harder to understand! Any ideas?

My Aussie ATPL notes are about 10,000km away.
Practically wise, just keep on profile with the instruments and hope like heck you can see the PAPIs when visual.
To be honest, it's the touchdown and braking that's more of a hassle WRT heavy rain.
However, Airbus has something to say about it.
