TK 737-800 "Eyebrow" Question

Mon Dec 04, 2006 12:33 am

While looking at some pictures of 737-800s of TK, I realized that the eyebrows of this particular airplane were removed... I know that the new ones are now being delivered without but why did they feel the need to remove the eyebrows that had been there for a long time already? Does it help with anything at all?

I was wondering the same thing and can only assume one reason: It may have been in for MX and they decided to take them off.

Saves some weight--with fuel prices as high as they are, every little bit counts. There may be other reasons too.

Well, WN is removing theirs for the maintenance cost so that could be the same for TK....

I have heard that pilots don't use them anymore, and some cover them with newspapers to reduce glare.

All that I know of is that it was a 1960's requirement from the FAA of minimum windshield area and to increase visibility in banking maneurves.
But readucing glares and weight sounds fine to me. But actually how much weight is reduced by removing the "eyebrows"??

Cheers.

It has more to do with mx costs. As you can imagine, a piece of aluminum requires far less attention over time than an electrically heated piece of laminated glass. Plus it looks cool  Wink

See http://www.boeing.com/news/releases/...05/photorelease/q1/pr_050126h.html

According to Boeing they save 20 lbs of weight and 300 hours of periodic inspections per aircraft.

It is no longer needed due to advanced avionics, witch don't require so much light for the crew to do their job.

They are being removed to make some economy.
