Thanks CL300 - that is what I heard from the other crews who said they would go for ignition only with medium intensity rain or more, but not in clouds or drizzle. I am trying to understand, how much rain/water these engines can handle without continuous ignition. I have seen couple of videos on u tube where huge volume of water was injected into different types of engines while these engines keep full power - but my guess is that they all used continuous ignition. So, the million dollar question, is how much water they can take without any protection...
