Wipers on B777
 

What if it fails?

The B747 has CB's on the O'head but the B777 doesn't.

Any Ideas thoughts?? ( and yes before anyone comes up with - go somewhere dry!!! I've thought about it!)

I've heard of one that occured an the Co- pilot landed...but surely there is a chance that both could fail making a diversion inevitable!!?!

If you're in the right place, you can autoland so your only problem then will be finding a parking space. Bad enough at LHR in the dry! :hmm:

When a wiper motor fails, whats to say that cycling a breaker is going to bring it back anyhow?
Wiper motors overheat, and cycling the breaker won't help it...only a cool-down will.

Speed??
 

Anyone know what the Max operating speed is??

(Say you wanted to test the wipers on approach and the windscreen is wet.)

Windscreens now have a special coating (hydrophobic I think) a bit like rain-x. Which means normally wipers aren't really needed in flt just for taxying.

Wipers are usually on seperate circuits. Like most duplicated a/c systems. To lose one would be unfortunate. To lose both would be just careless.:ok:

the new boeing philosophy (at least for the B777) regarding CBs are DO NOT reset in flight unless critical to flight operations...
