I arm the Auto Brake switch..However I have no way to determine if it is working.. As I slow down I hit the manual brakes and the inop lights up.. The switch does not automaticly return to off...not sure it should...Also are there Hydrolic Pump switches..?? If so where are they...ThanksRay Lunning

The brake behavior you describe is correct real-world behavior. When you apply brakes manually while autobraking, it's supposed to disengage the system, and you get the inop light. The autobrakes automatically disengage at 40 knots groundspeed, and again, you'll get the inop light when they do. The switch is not a solenoid, so it does not move back to "off" by itself. If you're wondering about the system working, crank the autobrakes all the way up for a landing...it should give you a pretty noticeable decel on landing rollout. Alternatively, you can go into the logging page of FSUIPC, put offset 0BC4 into one of the boxes, select type U16 in the dropdown box, and check the "use ADVDISPLAY" box, and you'll get a green window showing the actual brake application value in the sim. 0 is no brakes, 16383 is full braking. Autobrakes will give you something less than full braking, depending on the setting.The hydraulic pump switches are on the overhead panel, the two for system A are engine driven and the two for system B are electric. See the docs...there are indexed pictures of all the subpanels. There is also a hidden hydraulic system pressure gauge in the new version, it's displayed by clicking on the empty panel plate below the #1 oil qty gauge (also explained in the docs).RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

OK! I see the hyd. switches...Also the Autobrake is working.. Issue is the Airspeed gauge.. The numbers in the middle will not go below 045.... Not sure why...is there a switch some where for this..??Ray

That's real-world behavior. Below 45 knots the system is unreliable.CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO
