Delta L-1011 IFE Questions

We all know that Delta has retired their L-1011s in 2001.

I have a question about the IFE on Delta's former L-1011s.

As far as I have heard, Delta's L-1011s were originally equipped with a Telephonics IFE system with reel flim projectors (correct me if I am wrong). The headphones I believe were the tube-style ones. However, in the early 1990s, the Telephonics IFE system was replaced by a Panasonic/MAS system featuring CRT projectors similar to those on most of Delta's 767s. The system was in fact more modern than what most of the domestic 767-300s currently feature: for example, the passenger controls were the digital-style with buttons (rather than dials) for channel and volume and an LED display showing the channel number. The L-1011-500s (and possibly the -250s) even had the Airshow moving map program.

My question is: Why would Delta upgrade an IFE system on aircraft that would be retired less than 10 years later? I know that the domestic 767-300s are slated to get the new AVOD system, but this new system helps Delta be more competitive on transcontinental routes. I don't see why would Delta would replace the film projectors with CRT projectors on the L-1011s.

If it was to change from heavyweight film canisters to lightweight videocassettes, it would make perfect sense.

Maybe they wanted to offer a better product and keep their customers happy by offering something other airlines may have been offering as well?

When DL installed the newer systems into the Tristars, it had no idea exactly when the fleet would be retired.

Not sure about the -250s, but consider that the L15s flew the longest haul segments in DL's route system back then (including the transpacific services), and the Airshow was an innovative product at that time which helped entertain pax on these very long flights.

Very good point.

I wonder why Delta never installed Airshow on the 757s, 767-200s, domestic 767-300s, L-1011-1s, and MD-90s. I believe that the 767-300ERs were the first to feature Airshow, followed by the MD-11s, L-1011-250/500s, 777s, 737-800s, and 767-400ERs. I know that with the older Rockwell Collins systems on the 777s and 767-400ERs, Airshow is integrated into the system. The 737-800's IFE system is made by Panasonic/MAS, so the Airshow system is separate from the IFE system.

The 777s, international 767-400ERs, BusinessElite on the 767-300ERs, and Transcon 757s now use a similar feature from Panasonic known as iXPLOR. I assume that the domestic 767-300s and 28 Transcon 737-800s will get iXPLOR as well.

Well, the system that the L-1011s got in the early 1990s did not add any new features to the passenger (except maybe Airshow), it was just an upgrade to the latest technology at the time. The new system was more advanced than on the 767-200s and domestic 767-300s.

The domestic 767-300s are getting a more revolutionary (rather than evolutionary) upgrade, with video going in-seat and featuring AVOD and satellite TV.

Also, I believe that the four P&W-powered domestic 767-300s currently have the digital-style IFE passenger controls with the buttons and LED displays, rather than the analog dials like most of them feature. They also feature taller seats than most of the other domestic 767-300s. I believe I was on one of those aircraft last year on SJU-ATL.

The video systems were upgraded from Sony/Transcom Beta to MAS SVHS systems in the early '90s. The video projectors themselves were never changed and remained a Sony/MAS hybrid system with a MAS controller and two SVHS players. These were for the majority of the domestic L-1011's. I'm not sure that DL had any reel projectors installed from the factory due to the fact that DL never showed an inflight movie until 1980 (not sure about the -500's) . EAL L-1011's had a total MAS (video/mux) system installed at DL when those reel projectors were removed.

DL standardized mux systems in the early '90s to a much more reliable MAS system. The PA/UA/AC planes all had a Hughes system (a 747 system) while the DL/EA planes had the Telephonics system.

Also, remember that with a reel system you have one movie loaded and that's it. A videocassette system can show several movies during a flight.

Hmm, interesting. I noticed that on my recent ATL-MCO (Flight 1007 July 12) flight on one of the domestic 767-300s (with the leather seats), the projector lenses said Sony on them, yet the IFE control center said MAS on it. The passenger IFE controls were old-style analog dials. However, on a flight last year (SJU-ATL also on a domestic 767-300 with the leather seats), the passenger IFE controls were a more modern digital style with buttons and LED displays. The controls looked similar to those on most of the older 757s without the Song IFE (i.e. on the side of the armrest), but with the addition of a call button and reading light button. This is one of the four P&W-powered aircraft, is that correct?

Also, all of the 767-300ERs have the digital style controls, is that also correct? However, I think that some of the newer ones may have the controls on top of the armrest instead of on the side. I know that some of the newer 757s before they were converted to Song had the controls on the top of the armrest, all Transcon 757s now have them on top, with orange illuminated keys and an orange (rather than green) LED display.

I think you answered your own question there. The domestic 763's will probably leave the fleet within the next decade. The L-1011-500's flew long haul, so it's a no brainer they wanted to be more competitive on the intercontinental routes.

Seems like a no brainer, especially for the 757's, which should be in the fleet for some time to come. Maybe a couple years of profits is what DL is waiting for, same might be true the 787 order..

A bit off the topic, but were the four P&W 763's acquired second hand? They are not the ex-Gulf Air birds, are they?

No, they are not the ex-Gulf Air aircraft. The ex-Gulf Air aircraft are 767-300ERs. These four P&W-powered 767-300s are the last four of the non-ER 767-300s.

It is generally accepted in the industry that cabin upgrades need to take place about every 5 years. Yes, I know, some companies have a longer cycle, but seats start looking and feeling very tired after 5 years of continuous use. Just imagine how many hours people have been sitting in them...
So if you're replacing the seats, you might as well go for the whole upgrade including IFE.

Yes, I know that Delta replaced the old seats on the L-1011s. The L-1011-1s got seats similar to those on the domestic 767-300s, while the L-1011-250s and -500s got taller seats more like those on the 767-300ERs.
