Flew LHR-YVR a couple of days ago on a 744. Noticed that there was a new IFE system installed. Full touch screen menu with tv and movies you can view whenever you want. No continuous cycle as previous flights had. It must have been very recently introduced, as I flew YYC-LHR 2 weeks earlier and this system was not installed, or perhaps only installed currently on certain aircraft. I have to say it's a great new system and kept me very well entertained. Anyone experience this also lately on BA flights?

The system was incredibly easy to use. I really enjoyed it. It is available in all classes. I was in World Traveller Plus, and the only thing was some of the games said available in WTP due to the different controld used in WTP for the IFE. All in all I think a great improvement over the old!

I've just used LHR-HKG-LHR and it was excellent. The selection of movies, games and short programmes was one of the best, with plenty of choice. I was quite content playing who wants to be a millionaire on board. I was somewhat disappointed though by the selection of music. In short it was rubbish. It wasn't a huge problem though as I had my trusty iPod.

I think some games are just not all. I agree it was a blast playing tetris on my flight. I agree the selection of tv and movies and being able to start, stop, pause, rewind whenever u want is a great feature. Again I also agree music selection is crap.

The ystem, when it works is excellent. I had it on my 747 flights to JFK last month. On the way back it kept breaking down however and had to be reset 3 times and in the end the crew couldnt get it to work. When it did work itwas excellent however
Next Flights: EI DUB-LHR A320, BA LHR-SFO B744, UA SFO-LAS A320, BA LAS-LHR B744, EI LHR-DUB A320

The AVOD is great when it works. I've had it flip out and not show anything, even to the point of the whole plane having to reset.....pain in the ***.
Was in F Jan 3, and volume was stuck on MAX volume........after the CSD reset, was still stuck on MAX volume.....I gave up and went to sleep. The only way I could deal with it was plug in the head phones, but have them away from my ears.

The system is indeed a much needed improvement. There were a number of issues with the implementation, which have for the most part been sorted. There are still some issues, usually with individual seats, but compared to a few months back, the system has settled in nicely. Had it on flights I did in December and it helped pass the time. The 777s should start getting the system this year, but not all of them will receive it, due to a different system currently in use on some of the 777s.
I flew LHR-JFK in April and I had the AVOD on my flight. I travelled out in WT and back in WTP and both cabins had exactly the same features, films, games and music. I have to agree that the selection of music could be updatedto a better standard but AVOD is so much better than BA's old IFE system

Nice to see BA investing in their product; with all the enhancements that other airlines like UA, BD and others are making its about time they make sure their product continues to stay ahead of the rest and provide value.

Hi all. Perhaps someone can enlighten me here, but just why ARE AVOD systems seemingly so unreliable? Every time I've flown with AVOD there have been problems (on a recent First Choice flight to Kenya we were told the entire in flight entertainment system would be unavailable, and that they had been trying to fix it for 2 hours etc etc, only for it then to mysteriously work perfectly right after takeoff and for the subsequent 9 hours), and every time I read about airlines introducing it there always seem to be serious reliability problems. How is it that aircraft can contain computer systems to fly the thing inch perfectly at several hundred miles an hour over thousands of miles and put it down on a 45m wide strip at exactly the right speed, and yet can't contain a system to show different programs at once reliably? Hell, surely if they throw enough processing power at it companies can get them to do it? I mean on my laptop I could watch 2 films at once easily enough, so surely can't that just be scaled up? I'm aware I'm very probably being hugely naive here, but does anyone know any intrinsic reasons why computers are generally so good and capable, but AVOD systems are so often absolutely rubbish?
Sorry if that appeared something of a rant, but it has been getting to me for a while now why nobody seemed to ask this question!

Hard to say. Remember billions are put into the systems that have developed and has given us these amazingly precise and incredibly advnaced machines. I doubt near a fraction of that has been put into the IFE for the a/c. I guess they're are some kinks to work out tho.

I work on an AVOD B777 every day. I find that the actual system is very reliable, but the biggest problem is the bits that the passengers can see. Every day at least one handset is presented to me, ripped off its cable, every other day one of the TV screens happens to fall off its arm, and whenever an individual seat is not working it is always someone has managed to kick the plugs off the underseat controller. I think that AVOD would be great without pax!!!!
We introduced a new AVOD system two years ago, and the improvement in overall reliabilty has been outstanding. The older pre-AVOD system was always inop, the new AVOD system very rarely.
The problems are a mixture of bandwidth and processing power.
When movies are on a loop, only one "copy" is broadcast through the a/c which you watch by accessing the channel it is on. With AVOD, each additional passenger viewing the same movie has a marginal effect on the amount of processing power drawn (because the same movie file is being accessed again). Believe it or not, most fixed IFE systems still run on old 486 processor technology. For those too young to remember what that is... you have not bought a PC with a 486 chip in about 10 years...
Also, each passenger watching a movie has to have that movie delivered to their seat by cable (hence the bandwidth issue). In the old systems, only one channel of the movie was being pushed through the network of cables, whereas on AVOD, effectively each passenger accessing a movie is creating an additional "channel" that the network has to provide space for.
You will find that the AVOD systems work better on night flights - more passengers are asleep, and so not overburdening either the system. Also, it depends a little on the choice of movies. If the choice is really good, then passengers will spread across lots of different movies, but if the choice is pretty poor and there is only 1 decent movie, everyone tries to access the same file and the processing becomes much more difficult leading to the system to crash.
Personally, I think that the new personal systems are the way to go... like Airvod on JetStar... the choice of stuff to watch is just as good, but because you arent sharing a network with other uses the system issues dont exist. In addition, as TristarSteve says above, the other problem is that the equipment peripherals can break - screens, controls, headset jacks etc - which on an a/c with fixed systems means that that seat is without IFE until there is a maintenance stop... with portable, you just hand the passenger another unit and you're laughing.

Firstly, on AVOD systems you are dealing with multiprocessing systems trying to provide data to a large number of "clients" (i.e. each seat in the damn plane). IFE systems are, in a simplistic manner, a set of VCRs broadcasting the same tape over and over through a number of channels (i.e. you cannot rewind, stop, pause, etc).
AVOD implies processing data by a computer and interactive features which require a computer. There is a golden rule in software engineering which says that the cost of detectinv and removing an error in any given program increases exponentially over time (i.e. the more errors you remove, the more expensive it becomes to detect/remove the next error). At the same time, the probability of a program having errors increases with the number of lines of code. By the end of the day, it becomes too expensive to search for more errors.

The larger a networking system becomes, the more complexity is added to gain resilience. If and AVOD system would be as resilient as a Media computer, these AVODs would require redundant power supplies plus a redundant and fail tolerant architecture in the hardware. Needless to say that would also require more complex software.
Hardware space/weight is also an issue for AVODs so there comes a point when it is not reasonable for the airline/manufacturer to invest more money in a bigger or more powerful AVOD system. Obviously, as technology matures, the AVOD systems become less prone to errors.

: The BA AVOD is not actually a new system. It is the old IFE system with a simple upgrade. The screens and handsets are the very same as the ones onboa
: Can't speak for BA but on AC, it's VERY easy to use. No "crash" to mention on my few flights on the A319/20 but one general system reset on one 77W f
