In RL, does the A10 use the trigger as 1 stage or 2 stage trigger? Sorry if that's another stupid topic...

Da FAC?
Yes, they do.
Depressing the trigger to the first detent activates PAC-1, the 2nd detent fires the gun.

Thanks Stuka
Stuka, do you know of any literature that describes how the PAC works? Or can you please explain? Thanks.

From the DCS manual:
on EACGun Strafe Using PAC
PAC assists by stabilizing the aircraft during strafing and allowing much greater round density on target because the pitch and yaw will be controlled during gunfire to keep the rounds from walking from the initial target point. PAC does this by applying elevator and rudder control through the SAS to stabilize the aircraft's nose during gun fire.
In short: The same system that is used for the autopilot, is used to stabilize the plane onto the point where your gun pipper is on, once you reach PAC-1.Enhanced Attitude Control System (EAC)
The EAC system was one part of the LASTE update to the A-10A that provides an autopilot capability. EAC uses sensor data from the Embedded GPS INS (EGI) navigation system, the Central Air Data Computer (CADC) and the SAS, and then provides input into elevator and yaw as part of the SAS.
The EAC system provides two major FCS functions:
Precision Attitude Control (PAC). In PAC 1, pressing the trigger in Gun master mode will trim the aircraft through SAS to keep the gun pipper on the target point.
Low Altitude Autopilot (LAAP). This includes the autopilot modes of Altitude/Bank Hold, Altitude/Heading Hold, and Path Hold modes.
Combined, the FCS of the A-10C provides a good, stable weapons platform to accurately employ weapons from. However, unlike an F-16 for example, its FCS is not a fly-by-wire system and the pilot is much more in charge of what the aircraft is doing rather than being a voting member. As such, the A-10 is

Hypothetically, you think you have the pipper on target so you go into PAC-1 mode. However, after flying another half a mile down the slant line when you're about to start firing, you suddenly notice you're still a bit off. What to do next in the upcoming seconds? You try to adjust and thereby slightly push against PAC-1, or do you let go of PAC-1 and re-adjust, taking the risk you overcompensate and will have to abort the run?

Never 'fight' PAC.
So in the case you want to adjust, you disengage PAC, adjust, and engage it again.
If in the end stuff doesn't look right: abort.

OK so to conclude, PAC-1 is only meant to keep your aim where you placed it up until the point you're at an appropriate distance to starting sending the rounds or rockets. It is not meant as a damping tool to help you set up your aim more precisely.

You use PAC-1 for guns, not rockets.

I thought PAC-1 is used from time to time prior to a rocket attack in order to remain stabilised when they have set their aim. Guess that must be a simmer's trick then and not a real world one.
