Taxiing the A321

[jamieb0202]

Hi guys,

I'm finding it a great struggle to taxi with the A321. As far as I am aware, like the A319 and A320, after a short burst of power to get it rolling, the A321 should taxi comfortably under idle power.

With the PA model, I find that I need to increase the throttles slightly and keep them there in order to keep the aircraft moving. If I do return the throttles to idle, the aircraft will slowly come to a stop. This is the case, even with a reasonably lightly loaded aircraft (80-90% load factor, 30% fuel load and extremely light cargo load).

Is this desired, or is there an error?

Thanks for your help.

The A321 is slightly underpowered, as it is in real life. Same powerplant options as the A319/A320, same wing, except the aircraft is significantly longer. The handling characteristics you're feeling are very realistic. I cheated and bumped up my power a little bit in the .cfg (nothing rediculous), but its realistic as you have it right now.

It is true that the A321 is longer but although it uses the same powerplant series it does has a more powerful thrust version of both the CMF56 and IAE V2500.

Static Thurst for A320 aircraft

CMF56 - ranges from 22,000lbs to 27,000lbs

IAE V2500 - is 24,800lbs

Static Thrust for A321 aircraft

CFM 56 - ranges from 30,000lbs to 32,000lbs

IAE V2500 - ranges from 29,900lbs to 31,600lbs

Therefore the aircraft should not be underpowered.
