<DIV> In an extreme case, the airflow traveling perpendicular could actually cause a vacuum in the pitot tube.</DIV>

<DIV><FONT face=Arial size=2>While recently evaluating engine / prop combinations (very top secret), I noted something that looks useful regarding snaps. During both up and downline snaps the speed signal drops to zero for a period of time roughly equivalent to snap duration. It appears that possibly airflow separation from the wing includes the pitot tube. Upline snaps also show a marked decline in ascent rate during the snap. </FONT></DIV>
