FSX Airbus's fly-by-wire

[Mace 1,927]

I know many of you flying the FSX A321 have been puzzled by the "nosedive" on final approach initiated by the FBW computer. Well...I found this: http://fromthecockpit.com/Flight_Controls.htmlwhich is written by a senior Airbus captain. The relevant part is...there is some artificial feel (in the stick) built in during certain phases of flight. For instance, when we're about to land and the plane (Airbus) in the "landing mode," the stick will need some back pressure from the pilot just as is needed when flying with a traditional yoke. This is done deliberately to make it feel more natural to the pilot. ...end quote...RhettAMD 3700+ (@2310 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 2.5-3-3-8 (1T), WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian case

Rhett,"Landing mode" comes in at around 40ft. The trim forward is very very subtle, it really doesn't need that much back *pressure* to compensate ... and it is pressure you apply, not a conscious rearward movement of the stick, you'll be going back up if you do that. The real aircraft most certainly doesn't "nosedive" at the gound.I'm afraid the FSX implementation of the FBW system is a bit basic, it's a step in the right direction but particularly in the (very tricky) final approach/landing phase it's not very good.Bottom line, the FSX FBW system doesn't mimic the real one. The flight model isn't that great either. The real aircraft flies just like a normal aircraft (exactly as it's designed to).On the upside, it does look like an A321 :-)Hope this helps,Ian

The "nosedive" I experience with the FSX A321 on final happens the moment I turn off the AP. I've only been able to fix that by turning OFF the 4 FLT CTRL buttons on the right hand side of the overhead panel before staring the flight, which pretty much disables FBW.I only know one Airbus pilot who flies the A320 for United and he tells me when they disconnect the AP on final, the aircraft continues flying without the FSX A321 "nosedive" effect.Kerke

>The "nosedive" I experience with the FSX A321 on final>happens the moment I turn off the AP. You should also see a nosedive on short final, too.RhettAMD 3700+ (@2310 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 2.5-3-3-8 (1T), WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian case
