Flip-down Vs. Over-aisle LCDs - Difference In Cost

Sat Dec 27, 2008 1:19 am

I was wondering, does anyone know what is the difference in costs between an IFE system using flip-down LCD monitors below the overhead bins vs. fixed LCD monitors over the aisles?

The flip-down type below the overhead bins seems to be quite common on 737NGs and A320 series aircraft. The fixed LCDs over the aisles are quite rare on narrowbody aircraft, but are found on many widebody aircraft. However, AA will be installing fixed over-aisle LCDs on their 757s.

I assume that the flip-down monitors cost more, however, does anyone know the difference in cost?

The flip-down hardware almost certainly costs more on a per unit basis, since the screen is bigger and you have the flipping mechanism. However, the overall system has got to be cheaper since you've got far less screens and wiring, and no seat boxes.

Not to mention less weight overall.

Sorry to nitpick, but aren't most TV's that are located over the isle not LCD, but in fact tube/CRT?

As original equipment yes (as seen on many 757s), however in recent years these are slowly getting replaced with LCD screens.

The cost savings in longevity and weight are tremendous, couple with the fact that the CRT tubes themselves are probably getting harder and harder to acquire.

DL actually has over-aisle LCDs on their domestic 767-400ER aircraft, but as they are converted to international, they will be replaced by in-seat AVOD PTVs. DL has also recently installed over-aisle and large bulkhead mounted LCDs (replacing the CRTs and projectors, respectively) in the Y cabin on their 767-300ER fleet. However, they will also soon get in-seat AVOD PTVs once they get the new staggered Thompson Cozy Suites in Y.

AA will also be installing over-aisle LCDs on their 757 fleet in Y, replacing the old CRTs.

And also, the flip-down LCD screens are rather rare on widebody aircraft; I have only seen them on a few Airbus widebodies mounted over the center of the aircraft.

Believe it or not, the price for provisions for the flip-down PSU screens are cheaper (OEM option price) than the overaisle provisions (by half). There is no option for PSU-mounted LCDs on the 767 and there is no option (standard options, that is) for the overaisle monitors on the 737. Obviously, an aircraft can be retrofitted after delivery however they want...

I think the reason that the overaisle is more expensive is because of the additional wiring bundles needed above the ceiling panels. There are already wiring bundles (with harnesses for the PA system) running through the PSU, so maybe adding a video signal harness is not that much more difficult. Just a guess, though....

Flip-down screens are more difficult on widebodies (at least 767/777) because the PSU is not horizontal (like it is on 737/757). If the screen flips down it will not be horizontal to the floor and thus not be very fun to look at (you'd have to tilt your head).

There is no option for CRT monitors to be installed anymore (somewhat obviously).

What about below the center bins? I know there are a few 767s with CRT monitors below the center bins (such as AA's 763s). I have never seen any with the flip-down LCDs though.

Not surprisingly, AA chose to go with CRT monitors for their 738s. However, their new 738s coming in 2009 will have LCDs. I am guessing by your statement, they will be the flip-down type, not the over-aisle type that AA is installing on their 757s.
