    PRESN AUTO FAIL cas message on landing

    Got a PRESN AUTO FAIL message on touchdown yesterday. Anyone else ever get it?

    The only difference between my landing yesterday and a typical landing was that there was a 23 kt direct crosswind on landing, gusting to 37 kts. Pretty much right at the demonstrated crosswind component for the P100. I'm thinking it may have something to do with the crosswind although there was no bounce. In fact, the plane handled it quite well - the pilot not so much.

    I have gotten it while taxing. Cycle pressurization to MAN and then back to Auto has always cleared it.

    Thanks (Username Protected). Worked like a charm!

    Got this from Travis Holland, too: "This message happens any time one wheel lifts enough on landing to trigger the weight-off-wheels prox switch. Pressurization computer sees one wheel in air and one on ground and pops that message."

    Guess that crosswind I landed in lifted a wheel a bit.
