    Default IAC Effective Area

    I was logging some signals and noted that my DYNAIR and IACDES_B values do not match. As a general rule IACDES_B values are lower than the DYNAIR values by .2 to .4 g/sec. I have not changed the {B4403} IAC Effective area table. All values are stock. Since IACDES_B are lower than DYNAIR it's wants less air than it is getting. ??? So the table would need to shift to the left? Correct? However, since the values are off by < 1 gm/sec I'm assuming for all practical purposes they are equal. Does anyone agree?

    I believe IACDES_B refers to the difference between how much air is commanded in the Desired Airflow table vs. what it has learned using the STIT's and LTIT's. Corrections need to be made to the Desired Airflow table...not the IAC Eff. Area.
