>Altitude information would be better but both the altitude and >vertical speed comes via the staic port. After looking this is up again I see this going to require somemore research. The ADCs feed: Altitude Altitude Rate True Airspeed to the IRS. The IRS in turn outputs: Attitude Mag Heading Vertical Speed Angular Rates Linear Acceleration Present Position True Heading Ground Track Vector Wind Vector Whether the IRS uses any of the ADC info to calculate VS is unclear. The IRS should certainly be able to figure it out using the accelerometers. I do know that we've never fixed a VSI problem by changing the ADC, only the IRS has fixed this. I'm only talking about 757/767 here.
