April 21, 200521 yr I've noticed that the most recent deliveries of 737NGs have lost the eyebrow windows. Will PMDG release a model update to catch up with this trend?Jason Zhanghttp://forums.avsim.net/user_files/113754.jpg JasonFAA CPL SEL MEL IR CFI-I MEI AGI
April 21, 200521 yr I really liked those windows... what's up with removing them? Maybe it's a company option. I'd like to know why they designed the 737 with the windows anyway.Cheers,Victorhttp://www.precisionmanuals.com/images/forum/800driver.jpg Cheers,Victor M. Lima
April 21, 200521 yr The windows were so that it'd be easier to traffic by having a better view above. Now that they have TCAS II and such there isn't much need for the windows anymore. I heard removing them can save weight, but I'm not sure if I believe that.
April 21, 200521 yr Author As far as I heard those windows were required by an old FAA rule. That's why they can be seen on almost all the older airframes from Boeing. This rule was lifted recently so there went the windows on the newly-builts. Do they look good? eh...I think we are just so used to them. Jason Zhang JasonFAA CPL SEL MEL IR CFI-I MEI AGI

April 22, 200521 yr It also saves some maintenance work (hours) and thus costs.Have a nice flight!Aleksandar
April 22, 200521 yr >to be honest we hardly use the eyebrows so it isn't a big>deal, i heard it makes the cockit quieter and that *is* an>improvement if true.Yep, I'll second that. I virtually never look out the eyebrow windows. Usually the only time I pay them any attention is when I'm stuffing a briefing card up there to block the sun coming in...JohnB737 FO

As far as weight savings are concerned, there are the 4 windows that weigh about 10 lbs ea. and their associated window heat wiring. Taking into account the replacement cover plates, the weight savings should be in the range of 25-30 lbs.Cheers,JohnBoeing 727/737 & Lockheed C-130/L-100 Mechanichttp://www.precisionmanuals.com/images/forum/ng_driver.jpg
April 22, 200521 yr Just think how much weight they could save if they got rid of all the cockpit windows! ;)Lee Hetherington, PP-ASEL (KBED)
April 23, 200521 yr Hi all...From what I have read,the no-eyebrow design has been implemented for the two reasons stated previously-less maintenance time and the implementation of new TCAS technology,rendering them quite obsolete...I liked it with the eyebrows better though.... :)_______________________________Georgios Arkouzis http://www.ivao.org/data/images/flags/waving/small/GR.gif SX077http://www.precisionmanuals.com/images/forum/800driver.jpg_______________________________
