to be more precise engines -
I just started one of the real worlds and I was wondering how far does the engine get listed in the same group.
I have some 37- adv with 2 variants on the JT8D - 17 (and 17R) engines,
since they are not availeble on the used market atm I was looking into diferent planes and come to the 727 witch also is powerd by a JT8D-7.
Basicly asking if they will be under the same engine group.
No matter what engines you use, the 737 and 727 are not in the same aircraft family.
Additional costs for training/maintenance will apply. Better take another 737 no matter what engines.
I understand that the airplanes themselves will be in different famelys, but I was wondering more specificly about the engines.
Engine commonality is not important.
Well, i'm screwed then, 1 year+ wait on new 737s and none on the used market atm.
Ouch :o
The engines ARE considered common between the 732, DC9 and 727s because they're all JT8D first gen engines. However, from a cost perspective, engine commonality doesn't hurt nearly as much as plane type commonality.

Adding a 3rd fleet group is fine if you need to do it to get planes.
Your 18 year old CV-440s could be a bigger problem than commonality costs are. They cost 30k/month to lease, but 60+k/month in maintenance when you include C-checks. A brand new F27 will cost 60k/month to lease, but only 20k/month in maintenance. They also use 3 staff vs 5, and 20% less fuel. Takes about 8 weeks for a newly ordered one to arrive. And there are 500+ of them available used, even the old ones are significantly cheaper than the convair. 16 year old f27-300 is 31k to lease, 40k to maintain, 17 year old f27-100 is 25k to lease, 45k to maintain. The other 3 similarly sized turboprops available new (DHC-7, HS748, AN24/26) are also cheaper in terms of lease + maintenance, though those 3 are all worse than the f27 thanks to some combination of staff/range/speed/fuel.
so basicly get rid of the CV 440s....
Yep. If you want to use 40-50 seat turboprops, there are much better choices.
I went with the 440 s because there are plenty of them on the used market, cheap, maintenance not to bad after patching em up again, and good experience with them on the beginners world.
But I also can see your point about using 18-19 Y old planes an rising mainetnance cost on them - so I guess i will slowly phase em out again over the next 2 gameyears (have to make the credits for the new 737 I orderd by june 76 firstbefore i start paying penalties for terminating leases)
