Flying in the Rain
Dear all,
Wending my way back home the other day there were some fairly light showers along much of my route (not Cb type stuff), and through most of the showers I could easily see thru to the other side. I chose not to fly through the rain, and took the scenic route which kept the aeroplane dry, even though I wouldn't have been too bothered if we did get a little wet.
Thinking about it a while later on the ground I realised I don't know very much at all about flying in rain, even light rain. I'm not talking about flying near serious Cbs, just light rain and not for prolonged periods. Apart from regular use of Carb heat any other tips or warnings?

The first thing that comes to mind is the reduction of ability to see other traffic. Also to be considered is your ability to fly on instruments for a few minutes if you lose the horison, otherwise a shower can be useful to clean the airplane with.

UK? Think freezing level!
One of the most dangerous places to be is the light see-through rain from medium level cloud on a warm front above the freezing level. It can be made up of supercooled droplets Take an already cold plane without deicing into that for any length of time and you will probably only come out downwards.

Thanks Blu, and thanks Irv.
All very good points confirming my gut feeling to stay out of the precip.
It may have seemed like a dumb question, but I'll bet there are more than a few reading this.... we all learn something.
Thanks again.

We joined the circuit in a 172 in the middle of one of those sharp, heavy April showers. Zero visibility forwards, engine noise drowned out by the noise of the impacts, aircraft still flew normally. It was a new circuit to me and I am sure we didn't find all the corners properly, on account of the terrible vis.

In my opinion no question is a daft question if you don't know the answer. The only daft question is the one you don't ask.
You didn't say what aircraft you fly, but generally there is no problem unless (as Irv pointed out) you are above the freezing level ( use the OAT gauge ) or have recently been above the freezing level ( such that the airframe is below freezing).
The reduced visibility is fairly obvious, but one effect that hasn't been mentioned is if you have a wooden prop. Without leading edge protection, a wooden prop will suffer anything from mild pitting at the tips to almost complete destruction in rain depending on the drop size. I assume hail is even worse, but if you're in hail you will be so close to a CB that the prop may be the least of your worries.

Another light rain issue - fine while the fan's running on the front clearing your screen. Turn base, carb heat, throttle back... all of a sudden can't see out. Not so good when trying to land!
Add a crosswind and the one time I had to do this I was pretty uncomfortable - had to come in a bit shallow on account of needing to use throttle to clear screen. Wished I had wipers

The great thing about rain (or flying in pretty wet clouds for that matter) is that the plane gets nicely washed; not a bug left anywhere... 
But you need to be proficient on instruments and navigation if you hang around it for more than a few seconds. This is what I find odd about the Night Rating; you can do it with minimal instrument skills, but under an overcast sky the vis could be zero - this is 100% IFR.

Just remembered something else.
I hadn't flown cessnas much until this year. A month or so ago there was a light shower passing through the airfield as we were in the circuit. In the old pa38/28 you'd still be able to see, but a 152, cripes you can't see a thing !!!

Another point: If flying in rain, make sure you switch on the Pitot Heat. Years back I was flying a Tomahawk in heavy rain in Holland, without the pitot heat on, and some water must have got into the pitot, because the ASI started behaving like an altimeter. Made landing interesting: Pitch and power basics again.
Rain not only washes the bugs off the leading edges but will also take the paint off them if the coating is in any way deficient. It will also take the paint off a metal prop, the varnish off a wooden prop with leading edge protection and the leading edge off a wooden prop with no leading edge protection.

flying through showers
a little food for thought...
If you see a little patch of showers dead ahead, clear on the other side. I say, fly through it. Get a little experience, experience the sensation.. As you never know, one day you may be forced to fly through rain, be it heavy or light. At least if you have a play in some light showers you will know what your in for should you be surounded by rain..
