Dear Staff,

now, we have a new toy to play proffesional......NGX
And Guys, how much is the Cost Index from Air Child 737 ?
Thx
 
It would indeed be convenient to hear an official management statement for the CIs for different types (and not only the 73x family). In the real world most companies use CI of somewhere between 22-26 for the 737 and 26-30 for the 738, although differences can be significant between airlines. I personally use 24 for the 737 and 28 for the 738 on my Air-Child flights so far.
 
Thx for your fast replay Svilen.
 
Please don't get me wrong, guys, but I sometimes wonder why people are literally begging for regulations and restrictions ;)
We will have no company CI as long as we don't have the business simulation implemented. Why? Because it makes no sense. No matter what CI people use, the effects will not noticeably show anywhere.
A cost index indicates the (possibly best) ratio between flight performance and fuel cost. So it is always directly related to the airline's financial management. CI's can frequently change, according to current fuel prices. At the moment I think it's rather pointless to force our pilots to stick to a regulation that we can not even control. Once there's a business model it will be different.

That's just my opinion. Inofficial and, as usual, open for discussion. :)

Edit: For some basic information on cost index strategies, here's a nice document from Boeing:

Point taken, Peter ;) And we do appreciate the freedom and variety of options that Air-Child provides in terms of career models, a/c types, routes and realism levels. However some value has to be punched in those FMC's if not for other reason, then at least in order to complete the preflight config and for the pilots to have reasonably accurate and realistic a/c performance and flight times without going into the extremities of excessively low or high CIs. :) So just as general and simplified reference (ignoring all possible CI fluctuations) for those pilots who are interested here's a list of the values some real world operators use (not only for their NG fleet but also for other types).

... you have a match point here :yes:

It's certainly not very realistic to use a CI of 400 on a 738, just by guessing. But mostly one can find hints or suggestions in the add-on's operating manual. At least I don't know of any freeware where you can enter a CI. But I maybe wrong.
 
Svilen, thank you very much for that 8)

I'm allways using CI 80 for my 737 and 738. Why?
10 years ago, the first realistic aircraft for the sim was the 767-300 Pilot in Command from Wilco (former Level-D). Created allso by Eric Ernst, a real Amarican Airline Pilot. He was talking that American Airlines was using CI 80 for this heavy bird. So shur, I was using also CI 80 for my flights. That's it! And I'm using it right now, because it dosn't matter at the moment, wich CI I'm using.

But like you, I'm also waiting for the day, till we have finished the economic part. Stand by please...
