Engine spool up is still way to fast from ground idle. See this video at 6:47 for a perfect representation:

EGT and fuel flow should increase slightly when the packs are using engine bleed air. You should notice this on the ground after engine start, currently not simulated.

Any updates on this?

When the spoilers are disabled by a hydraulic failure, or disabling the hyd system the rate of roll remains unchanged, it should roll much slower without spoilers.

Check out 737ngdriver on youtube, he has just finished a complete series of tutorials on the a300 that are very good

When refueling the aircraft, the fuel quantity always starts at zero even if there is fuel in the tanks.

The VLS band does not currently increase when speedbrakes are extended, this should increase and the aircraft should react accordingly by stalling at a higher airspeed.

Question regarding the maintenance and wear function on this airplane, if you let the engine oil get too low, or the tires and brakes wear out, hyd oil run out etc., Will these components actually become inoperative?

Idle n1 is around 25%, but should be around 22%

When toga power is set the egt is about 100-200 degrees low compared to the real aircraft

I cant speak to everything in your post, but the reduction in volume of the buzzsaw effec5 at the highest n1s is actually correct, its called "coning". During descent some engines produce more bass at at lower n1, at cruise all of the high frequency sounds the engines make should dissapear, so it might sound like the engines get louder at lower throttle settings. This definitely happens irl on some jet aircraft, ive never flown in an a300 though.

Great explanation, didnt know that about delta p but it does make sense. Do know what the actual reason is for the tas related effect?

100% agree with these observations especially the part about the relationship between engine sound and TAS. Another nice touch would be to vary the pack intensity slightly based on bleed pressure so when the engines spool up slightly from idle you can hear the pack sound increase slightly.

When advancing the thrust levers the engines should spool up much slower until about 30-35%n1, the egt spike and stabilization is also not there.

It looks really good. Regarding the wear and tear, if the oil level gets too low and isnt refilled will the engine eventually fail? Are any other failures modeled that can be triggered from abuse such as low hyd fluid, hot starts, icing, etc?
