FAIB B737 vs AIA 737

Featured Replies

I have just tried it with the FAIB B737-700w and it seems that it works! The plane is now behaving much better after touchdown. Thanks John for the great tip.  :dance:   :drinks:

Glad it worked - its so long since I have done it I was worried I might have missed something in my list.

Hi,

 

it would be interesting which of the copied values changes in fact the mentioned behaviour. But anyway - this will be my work at weekend. Thanks John!

Editing my previous post got impossible, so I use a new one:

Within some fora I found one member declaring that the values

 

toe_brakes_scale (under the [brakes] section)

and

min_throttle_limit (under the [GeneralEngineData] dection)

are the appropriate entries to deal with.

 

But I'm confused by the recommendations from the named fora

http://flightx.net/board4-microsoft-flight-simulator/board26-flugzeuge-add-ons-f%C3%BCr-ms-flight-simulator/20958-ai-traffic-bremsweg-erh%C3%B6hen/

(unfortunately only in German). It's recommended there to decrease the value for "toe_brakes_scale" and to decrease the value for "min_throttle_limit" (as this latter is a negative value, increasing it would be correct instead decreasing). Obviously, they mean the correct thing as they recommend a "min_throttle_limit" around -0.2 or -0.25 or even near -0.025. And now the confusing fact - the values in FAIB's aircraft.cfg fit better to this recommendations than AIA's...

 

So if the deleceration behaviour doesn't depend on the .air file, there must be other parameters in aircraft.cfg by which it is influenced.

 

By the way Mike, do you have the v.1.2 of these FAIB Boeings installed?

Hi Harald,

 

I have checked the versions. At this moment, the only V1.2 model is the B737-400, all other models are still V1.1. But it seems that there is no difference between those two versions on the matter discussed. Before posting I have watched a B737-400 landing ( V1.2 ), and it was behaving just like the other ones after touchdown. Unfortunately, it's not only the Boeings that have this problem, but also the Buses.

 

I have read the links you provided and I find it very interesting - and not confusing at all. As I understood what they are writing, with "decreasing" they meant to decrease the amount of throttle used for reverse thrust. According to that post, a min_throttle_limit of -0.45 means that the plane will use 45% thrust for the reversers. So by INcreasing the value to -0.25, you are actually DEcreasing the amount of thrust used for reversers to 25% of max thrust. 

 

cheers

Mike

Yes Mike,

 

this is exactly the confusing fact for me - AIA planes use a higher amount of reverse thrust (-0.45) and have a better brake scalar (0.585) then - but they decelerate not as quick as the FAIB planes (-0.25 resp. 0.4)!

 

Btw, I also checked the differences between V1.1 and v1.2 (in my case, for the 737-700), and there's none within the most "suspect" .cfg entries.

Harald

Ah I see, and yes - that is confusing indeed. But it also might indicate that there is more to do than just changing those values.
