An old thread but thought I would add: I have recently jumped back into the airframe and have flown several legs upto and including FL240 with Pressurization working ok and no master warnings. If this helps anyone this is what I am doing ( I will look to post some FSX screen shots - plus I have some RW pressurization pics). prior to departure, I set Cabin Alt to 8600ft when I plan crz alt of FL240 this produces max Diff at crz. Since a I climb at an avg of 1500fpm I set cabin climb for atleast 700fpm to ensure I don't bust the max diff on the way up. I know the RW procedure would have you select aircraft crz alt +500/1000ft but agree the gauge looks wrong. Anyway hope this helps.

that's a good point, I better re-test tonight - it may well be the TRQ setting itself that I am managing ie: setting a little less than charted cruise TRQ for Alt & IOAT at those FL. stby...

I posted a response in the B200 forum which may be able to assist with b1900 handling: http://www.avsim.com/topic/388523-list-of-outstanding-issuesbugs-b200-edition/?p=3290739 "Very Old thread, but thought I might add what might be a solution/workaround. Re dutch rolling at higher FL, I found keeping your indicated airspeed not within 10 knots of the barber poll gives you a smooth ride at any FL. ( Tested upto FL290 so far - pressurization issues beyond that ). this applies to the decent also. I know some SOPs recommend barber pole to 10,000 then 250 and below. but I can manage a comfortable 1,500fpm descent TRQ's between 1200-1400 ft/lbs and RPM's 1700. reducing TRQ gradually as you get into thicker air. I hope this helps anyone out there frustrated with the yaw and rolling. btw: for those experiencing right hand RPM fluctuations on climb I find turning the prop sync off and manually syncing the props help once stabilized for a few minutes - prop sync back on."

I to am experiencing rivet line shimmering. Turned off AA in FSX and used NVidia inspector to drive AA. I will post screen shot when I get home. I am running with GTX 660ti. I downloaded a safe version (1.9.7.2) here: http://www.guru3d.com/files_details/nvidia_inspector_download.html

Hi Tim, Any chance you could drop a small video of what your experiencing on here or youtube? In fsx settings do you have anything ticked in regards to high level gusts or shear etc? If your running both gns530 and the FMS , turn the FMS off. A configuration that seems to work for me is two crew (86 lbs) each, 100 lbs fwd cargo and 400 lbs aft cargo, 100% aux fuel and 50% mains fuel. A notch of nose down trim. Approach flap, this usually results in 12 degree nose up attitude and 140 kias initial climb out to acceleration height. Sorry am almost at the bottom of the barrel.

Your climb out speed and attitude seem fine, what is your cruise KIAS? Do you still have a lot of nose down trim to maintain straight and level ? the yaw damper assists with stability at higher altitudes. Prevents the old Dutch roll. I engage it at 500 ft agl and take it off when in the circling area or 10nm. Re: your loading, i find the same when in that config you mention above I like to throw some ballast up front keep the cg away from the aft limit. Without a poh I am trying to work out loading and associated trim settings for take off. Cheers Mike.

G'day, I know you mentioned all looked okay, what is your climb out speed? What kind of Shake? Pre stall or more of an oscillation? Did you engage yaw damper at 500ft ? Cheers, Mike.

Flown a few legs in NZ: NZAA - NZGS NZGS - NZAP NZGS - NZWN NZGS - NZNS NZNS - NZQN NZDN - NZQN A couple in OZ: YSSY - YBTH YSTW - YSCB great aircraft!! have waited a long time for this one. waiting for the service pack to come out fixing the pressurization etc. yet to do any US legs.
