Hello Mike,
FYI I the later Garmins (I believe that includes the 196) will record flight tracks with Altitude, the Lowrance 500 and 1000 will not. I find the 3D track very useful for: 1) Aesthetic dimension for plots of our flights to give to friends that we've given rides to. E.g. if you use http://www.gpsvisualizer.com it will color-code the track according to your altitude. 2) Instrument training. Plotting your track directly onto the approach plate. How well was I holding altitude or glidepath? E.g. http://f2.pg.photos.yahoo.com/ph/cra...&.dnm=a4c5.jpg 3) Evaluating engine/airplane performance. Leisurely after-the-fact evaluation of climb-rate. Also, when did the wheels leave the runway on those short-field takeoffs? Where was I when I cleared that 50' obstacle? And how does that compare to book? This has become more important to me since I fly with a CS prop, I've had a bit of engine trouble lately, and I occasionally fly out of a 2600' grass strip in the Texas Hill Country (that's NOT the place I want to find out that my engine is not putting out max hp!) E.g. http://f2.pg.photos.yahoo.com/ph/cra...&.dnm=1d24.jpg Cheers, John Clonts Temple, Texas N7NZ |
