Feel free to use the picture if you decide to call Sporty's. Here is the image I sent to Sporty's asking for an explanation: http://img.photobucket.com/albums/v1...SportysE6B.jpg -- Dallas |

Ignore my last reply as I thought you had a real mechanical E6B, not these fake electronic devices. It does appear that you got a bum unit. Matt |

I entered the same numbers in my Sporty's E6B and got PA: 998 DA: 1910 Which is about the same as on the chart. Your reading of 2000 DA for 1000 PA is slightly off. You need at least 22 deg C for that. - Tom On Sun, 29 Apr 2007 17:20:43 GMT, "Dallas" wrote: My trusty Sporty's Electronic E6B does not agree with the Density Altitude Chart. My instructor is at a loss to explain the difference. Can anybody tell me what's going on? Here's a sample problem: Field Elevation: 1165 Altimeter Setting: 30.10 Temperatu 21°C ___________________ Using the standard chart: http://pacificrimprinting.com/densalt.pdf 30.1 in. Hg Pressure Altitude Conversion Factor: -165 Pressure Altitude: 1000 Density Altitude: 2000 ___________________ Sporty's E6B calculation: Pressure Altitude: 985 Density Altitude: 1894 The Sporty's pressure altitude is off by -15 feet and the density altitude is off by -106 feet. I can't imagine Sporty's marketing a flawed E6B, which one is inaccurate?- Hide quoted text - - Show quoted text - I got exactly the same... Jay Beckman PP-ASEL Lurking Chandler, AZ |

I got exactly the same... I assume you got the same as mine? As I look at the photo of the 2 Sporty's that disagree I can see that the 3 year old one on the left doesn't have some of the menu items like Timer, °C, Reqclimb, etc. It's pretty clear that they have created a new version. http://img.photobucket.com/albums/v1...SportysE6B.jpg -- Dallas |

DA = 1910... Can't resolve your claim about new/old by the photos...too blurry. Jay B |
