Quoting KFLLCFII (Reply 2): Quoting Flysherwood (Reply 1):
I have read that the SIA pilots that have flown it are really impressed with the A380.
What have the SIA maintenance folks said?
Its really too early to know. Even though they have presumably been trained on the aircraft, we will have to wait until the aircraft enters revenue service to get a picture. It has however been tested more than any other airliner to date so I cant forsee many issues arising outside the usual [and expected] teething ones.

Quoting Stitch (Reply 4): With all the time these birds have spent in the air during the past two years, I expect the airframes to be very reliable.
Indeed, I would think the dispatch reliability of the A380 will set a record for a new-in-service aircraft type.
Quoting Stitch (Reply 4): If anything breaks, it will likely be customer-sourced equipment (seats, IFE, galleys and lavs, etc.).
I would think even those things will be pretty reliable. The vendors have had ample time to tweak the equipment, albeit perhaps not in a real-world setting.
I'm going to guess that any reliability issues will stem from ground maintenance crews either creating dispatch issues or being unable to prevent dispatch issues as a result of their lack of real-world experience on the birds. But I think even those will be put behind them quickly.

Quoting A380900 (Thread starter): What is the expected reliability of a new type? What would be good, what would be worrisome? Airbus is said to have dispatched 20 people to Singapore to check on the plane. Can that last for long?
The expected reliability goes somewhat inversely with size, so even a mature A380 will probably have a lower reliability than an A320 or 737. That's mostly due to complexity.
Dispatch reliability over 95% initially would probably be considered good. Under 90% would be bad. The grey area in the middle is hard to fathom.
I doubt they'll keep 20 people in Singapore for a long time, but certainly until they get their 3rd airframe. Until then, there's no backup so they need to fix anything and everything that goes wrong on overnights. Apparently, they'll actually have a Panasonic engineer onboard to make sure the IFE plays nice.
Quoting A380900 (Thread starter):
What types have had the most serious teething problems in the last thirty years? How long to they last?
747-400 had a very rocky start in getting all the avionics and BITE to talk to each other. A320 had major issues with the FBW system at first. Given that we only get a new plane from each OEM about every 10-15 years, there are always a bunch of new technologies and they never work exactly like they're supposed to.
Quoting A380900 (Thread starter): Due to the ever changing configuration of the A380 until msn 26, should we expect much longer teething problems?
I doubt it. The final configuration of MSN 0001-0026 should end up pretty close to the production configuration once all is said and done. Plus, all of the little faults that come about during production should have been eliminated on the early airframes long before they get into a customer's hands.
Quoting A380900 (Thread starter): How long before a plane reache its long term dispatchability rate? How high can it be ?
I'm not sure how long it will take. Given the low build rate on the A380, several years is probably normal. Dispatch reliability can hit 99.7-99.8% on a narrow body, but I don't think any widebody fleets get that high.

Quoting Kaitak744 (Reply 6): I believe the best record for reliability of a new type is held by the 777-300ER?
If not, which aircraft is it?
I'm not sure a variant would be good to compare to a completely new type. However, the original 777 had a dispatch reliability rate in its first 3 months with UA of 97.7%, which I think was a record at the time and probably still is for a widebody.
Quote: In its first three months of revenue service, United Airline's 777 fleet has experienced a cumulative schedule reliability of 97.7 percent, he said. Schedule reliability is the industry measure for the percentage of time an airplane is free of mechanical delays and able to leave a boarding gate within 15 minutes of scheduled departure. This is a dramatic improvement over the introductions of the 767 and the 747, which achieved this level at 18 months and 38 months respectively.
With all the flight testing the A380 has undergone during the past 2 1/2 years, not to mention its more advanced design, I would think it should have no problem achieving a similar dispatch rate even though it is a quad and much bigger.

Didn't the 753 have an extraordinarily-good dispatch reliability when it was introduced? I thought that Condor had it up near 99% very quickly. Of course, that's a variation on an already-very-reliable airplane.
