what are these thing in the front for? Due that I can't see in photos any wiper blades I assume that this is for pilot and copilot Sticks their arms to clean the glass with their suit ..right?



  I'm joking but yeah ,I never figure it out what are these things and do citation lears doesn't have wipers ,how do they land in a storm ? 

if im looking at the same thing you are... im pretty sure that is part of the windshield anti-ice system.

I find hard to believe , (Not that I'm saying your lying Matt)
but see, how many have drive in one of those fancy cars? that has the glass? in the same angle? ,have you ever been in a strong storm ? in your car ? or in any those new cavaliers or mazda ?,I do and when its a strong rain ,we actually have to stop because even wipers can't deal with it, we stop because the rain wont allow us to see ,and we can crash ,Even that we are on the ground and not goinfg so fast and see bearly other cars that also have to slow down a lot in a highway ,
Now IMAGINATE In and airplane ,On Final 120 knots ,were we can't see the runway and runways without ILS are the most , we see bearly the rwy lights ..

I don't know ,I got of the blower thing ,but even a air flow in a storm that big which are very common can't deal with it, better than wipers ,I doubt and the stripes really fast on final ,many models with similar cockpit like this embraer has wipers

I mean I'm aware that flying with 250ias 300 ias would blow everything on the glass ,but on final (these planes lands at 100 ias according to some reading I saw ) We slow down ,no more aerodynamics ,again depends of what kind of storm ..

Unless they put a tube from the engines escape to the glass would have more sense ..

I'm not saying I don't believe what you said guys  ,but see, try to see my point     

If you have ever used RainX on yourwindshield, you will understand.  I hardly ever turn the wipers on.

Matt ,I believe you ,but what I really was trying to say was ,Was this blower very effective as the wiper? see?

But your Flight Crew Operation Manual part its been help full ,now the wings will have lights ,I didn't knew what was that hole in the sdes of fuselage ,its a flash light to see the wing on both sides 

Thanks

Hi alrot .

The water on the window is not as big a problem as you are thinking.  The impact speed spreads the individual rain drops out so much that they merge and form an even film.  I actually don't turn the wipers on on the CRJ 100, CRJ200, or the CRJ705 until we are on short final approach through about 500 feet AGL, and slowed to final speed, averaging around 130 to 145 KIAS depending on weight.  When you consider that we can takeoff with visibility as low as 600 feet, keeping the streight line in the rain for the roll out is not that hard either.  I just use the wippers for an added level of Safety.  As a mater of fact, we are even trained to land at night with just the runway edge ligths but no landing lights in use (we can do it, although we don't, we use the lights, and the wipers, and the localizer, and the Huds, and what ever is available).
