Flight Data Recorder

[Lamar Blair]

Hi Earl

Jerry and I are playing around with the Flight Data Recorder we are using it to help with some design changes to the Silhouette lots of good information. I was surprise to find out that my average flying speed was around 60 mph I though I was flying slow
I will give more information about our use later.

  The flight data recorder works well and provides useful information. Excel, and the ability to order the data, is necessary to make best use if it.  I feel that the altitude data are the most useful, in that they allow assessment of how well one returns to / maintains entry altitude, really important on things like vertical eights where the airplane passes through the same point thrice. Speed data are also informative and, I believe, can help one improve maneuver presentation.

  Having said that, I haven't used it as much as I would like. Getting access to the data port through the bottom of a Hydeout isn't very convenient. We've flown it in Andre's Smaragd and did not get consistent altitude data, probably due to pressure variation within the fuselage. The manufacturer provides info on how to attach a tube for exterior pressure pickup, we just haven't done that yet. I'm building a Partner which will have a pitot tube port in the wing LE, the exterior pressure pickup and easy access through the canopy. All post season fall projects, along with checking the recorder altitude / speed numbers for accuracy.

  Jim Oddino is using one also. We have both looked at voltage after the regulator. No surprises here, the regulator does the job. (Might be interesting to look at volts without the regulator.) Jim has effected a change in software to improve the range of voltage data acquisition.
