    Question Question about white arrow in speed tape



    Happy New Year to all of you, guys!
    2008 ... unbelievable how fast time goes by ...

    Let's start the new year with e new question: Sometimes I observe a solid, horizontal, white arrow in the speed tape of the PFD (PM Boeing Glass Cockpit)! Has anyone an explanation for me what this means?

    Cheers
    René

    Probably the speed predictor, when you push the throttles arrow points up, pull throttles back and arrow goes down.

    Hi Gwyn,
    unfortunately not, the trend arrows you mean are green and narrow and point up and down from the speed indicator.

    The horizontal arrow bar I mean is solid white and fixed on the moving speed tape, not on same place on different flights.

    I'll try to make a screen shot, when it appears next!

    White Line PFD

    Hi

    I think that is the V2+15 or the VREF+15 white arrow bug, but perhaps your graphics card or something is causing it to be drawn incorrectly. It should normally be a tiny pointed white line. I have never seen it like the screen shot posted (that is if it is indeed the +15 arrow). I presume you are using latest builds, if so, I think it points to a graphiccard / driver issue on your system.

    Regards
