Over-aisle CRT Monitors On A320s

Mon Nov 07, 2011 5:04 pm

Looking through the older cabin shots of the A320 series, I notice some aircraft have CRT monitors above the aisles - how many carriers installed these, are there any still flying today and why didn't they install LCD monitors as they were avaliable:

Also, I never know America West installed PTVs on their narrowbody fleet: did they not last long or did US remove them?:

I started using HP in 1997. They were already deactivated by then, and they remained that way until the US merger. Towards the end, HP started replacing seat banks wtih sets that didn't have the PTV's installed.

One must remember that HP was in dire financial straits for many many years. As time went on, the deactivated PTV screens started to really get scratched up and looked really really bad.

Amazingly, HP did have overhead LCD screens above every seat bank, that folded down for the pre-flight safety briefing. They retracted into the overhead bin/oxygen canister area when the briefing was over. The longest leg I ever flew on HP was PHX-DFW. I would assume that on longer legs, there was probably an in-flight movie on the A32x fleet...   On the 737 fleet, you got a "classic" pre-flight briefing by the FA's.

Wow, I only thought PTVs on a narrowbody was a fairly recent thing (e.g. 21st century with AVOD). Do you have any idea of what system this was (e.g. today with DL and Virgin America, they use the Panasonic eFX system)?

And I don't understand how HP went the way it did, though many airlines do sadly.

Yes, I think JetBlue was one of the first to offer them in Y.

America West installed the PTVs in 1994. They were an older generation system and one of the first entertainment units. They were not the typical PTV found today, but rather an extension of the inflight phone technology that was popular in the 1990s called flight link. They were used to play video games, get stock quotes and also had gate information. The company ended up going bankrupt, so the service was discontinued. Without the service, the monitor served no purpose. If they were still active today, I doubt anyone would even use them with today's technology.
If you have never designed an airplane part before, let the real designers do the work!

Ahh, that makes sense. Must have been really expensive to install back then, and I doubt back then people would use it to be honest!

Anyone got any ideas about the CRT monitors?

Which company, HP or the IFE system provider?    I know HP went bankrupt at least once, if memory serves correctly, shortly after buying used KLM 742's and trying to fly them to Hawaii and Japan...I know CO made a "strategic" investement in HP for a while, too, that ended about 2000 or so, and the company was financially hurting after CO sold off the HP shares...

Also, AA was one of very few airlines who went with CRTs for their 738s, when most other carriers were using LCDs. AA finally switched to LCDs for their newest 738s, and have also started retrofitting the existing 738s with LCDs.

Flight Link went bankrupt which ended the service. Flight Link payed to have the units on the airplane just like GTE/Verizon paid to have Airphones installed.

True, I wonder if there are any A320s still flying with these over-aisle monitors?

Probably a combination of both... HP have to cut costs, so can't afford to keep the service running and the system providor also goes bust so I guess that's how they quickly became obsolete!

I don't know why, I should think the LCD screens are cheaper to install and weigh less as well

Perhaps it could have been due to the flipping mechanism that reveals the LCDs, and AA didn't want deal with moving parts that can fail. Strangely, the ex-TWA 752s had flip-down LCDs both when they operated for AA as well as when DL first got them prior to installing AVOD.

True, the LCDs are a bit flimsy. On all the aircraft I've been on with them installed, the older aircraft with them on always seem to have problems (On a Cyprus Airways A319, they kept going up and down up and down for 5 minutes and on Icelandair recently, they were really slow at dropping and above one row, one didn't turn on until a mate of mine grabbed it and jiggled it slightly then it flickered into life!).

I think the LCDs are better as they're easier to see...

Still would like to know if any carriers still have CRTs installed on the A320s... I know A330s/A340s still have them down the centre on older aircraft xD
