Love this aircraft. However I have just one problem and that is when reducing the throttle the speed takes forever to decrease, and it taxis like a race horse.

Is there a way to make the speed and the engines respond quicker, lower the taxi speed?

Hello Steve,
yes you want to edit .air file table 1505. See the explanation at:

Air File Board, post March 2003
http://www.avhistory.org/scripts/MegaBBS/logon.asp

See page 3:

TBL 1505 will do this..

here is an example or some spool profiles :
[lost graphic as he moved server but repost the question and he will give a more recent answer as things have progressed since then]

The ones in the upper left are used most.. the two in the center are curves that I just `dreamed up one day' to check out the function.. and the J33 curve (don't recall source)
[ I do it was me!]
is a really slow spool. WARNING.. do not exceed the max number of points.. see Blown Engines post from a couple months ago!!

Oh.. not sure if X-axis is actually `time' but you get the idea..

Thanks George: I'll try editing the .air file. Went to the link but will have to regester later.

Hello Steve,
I'm Ian not George.
You need to update AirEd.ini quarterly from Herve's site.
latest says (its not really correct)
1505=*!Turbine Corrected Fuel Flow vs CN2,tbldb
1505h=Corrected Fuel Flow (x) vs CN2% (y)|FF(pph) = Thrust_Reference * F1505(CN2) * Delta_t/sqrt(Theta_t)|Shape affects spool rate|Not in TurboProps (KingAir)

get your updates here
Air File Editors
http://perso.wanadoo.fr/hsors/FS_Soft/fsairfile.html

see you soon at AvHistory.
