There is a lot in play.WorldTraveler said:I didn't ever equate thrust to thrust to range.
I did equate it to performance because that is what it does.
on clean runways and normal weather, the PW 333s have enough power to do what they need to do. but in higher temps, contaminated runways or other obstacles which are common, extra power makes a difference.
and DL's decision to now operate the 330 with all 3 engine manufacturers shows that there are clearly other factors at play that make it worth DL's while not to have tried to standardize the engines.
but you will never be able to figure out what it is. (and remember Rollers is the only choice for the 338/339)
Yes and know. They are getting sent out for work but its still a Pratt 4000 or a CF6 so shouldn't have to worry to much about the extra cost with all the PW4000-94s and CF6-80C2s in the fleet.jcw said:
Actually it shows they are driving up costs as it's more expensive to have so many engine types for one fleet
All true, but they don't work the 330 engines in-house. (and could overhaul and test cell run both the PW4068 and CF6-80E1))WorldTraveler said:you tell us... but since engines stay on the wing for years at a time and for now, DL doesn't overhaul those engines anyway (for now), it is likely the excess inventory is a whole lot less than you think.
and what you and I have no idea regarding is what DL actually paid for those engines or the service behind them.
given that GE and PW were both shut out for 100 onwing large engines plus spares for the new Airbus, it is clear that Rolls was willing to deal for the big order for new aircraft but GE had an advantage for a smaller order of engines for existing models.
and further, you clearly haven't figured out that DL has used its fleet COMPEXITY to increase its maintenance capabilities which it SELLS.
If DL adds some of the complexity of its own fleet to its MRO capabilities, it very well might end up better off.
DL Tech Ops is the largest airline MRO in the Americas.
not only can they do things that other airlines can't but they also know the cost of that complexity and how to make it work for DL's bottom line.
