rgmwa Posted April 4, 2011 Share Posted April 4, 2011 I will need to install a backup magnetic compass in my plane when I eventually finish it. I'm leaning toward getting a vertical card compass, rather than the traditional type. Are there any reasons not to go with the vertical card variety? rgmwa Link to comment Share on other sites More sharing options...
bilby54 Posted April 4, 2011 Share Posted April 4, 2011 Don't use the one that is made in the country that is better known for its rice dishes - they do not work during climbing or descending and would not calibrate in the A/C Link to comment Share on other sites More sharing options...

old man emu Posted April 6, 2011 Share Posted April 6, 2011 I see that Spruce and Specialty has a vertical card compass for $US278 which is TSO'd and made in the USA. I reckon it would be the ant's pants. OME Link to comment Share on other sites More sharing options...

geoffreywh Posted April 6, 2011 Share Posted April 6, 2011 I've got one..Works very well. Now with the dollar as it is, it's a bargain. Have you looked at electronic ones? Link to comment Share on other sites More sharing options...
Admin Posted April 6, 2011 Share Posted April 6, 2011 Why not look at Wicks...they have the Falcon one at $241 and others up from there: http://www.wicksaircraft.com/catalog/product_search_results.php/search=dmVydGljYWwgY29tcGFzcw== Link to comment Share on other sites More sharing options...
Allegro2000 Posted April 7, 2011 Share Posted April 7, 2011 RGWMA, I originally had a Silva hand bearing compass but it was put out by the tachometer the error was +10 east, -10 west. To cure the problem I put in a digital tacho, this made it better but not good enough. I decided to spend the money and put in a Precision Vertical card compass. The results are outstanding there is no correction required for the entire 360 degrees, it is a delight to navigate with this one. Ian has mentioned a Falcon which is the same type it is nearly half the price I paid, although I now do not regret the price as it made such a difference.

It's specifically a Northern Hemishpere one. If you bought it you'd have to get it recalibrated for the Southern Hemisphere, and there goes your $39 saving. You can specify a Southern Hemishpere one from Spruce & Specialty. OME ( I don't sell instruments.) Link to comment Share on other sites More sharing options...
Allegro2000 Posted April 7, 2011 Share Posted April 7, 2011 OME, My Precision vertical card compass was marked southern hemisphere. Allegro 2000 Link to comment Share on other sites More sharing options...

OME ( I don't sell instruments.) Ah, yes but if you purchased it through the Recreational Flying Shop, who are the Australian Wicks agents, you would pay the same price as on the Wicks site, and get a Southern Hemisphere one Link to comment Share on other sites More sharing options...
Brett Posted April 7, 2011 Share Posted April 7, 2011 Just a question ,,,,So do you need to have a magnetic compass fitted ,,, If there was one say in an electronic efis dash ,,,would you need 2 ? Link to comment Share on other sites More sharing options...
eightyknots Posted April 7, 2011 Share Posted April 7, 2011 Question: If a pilot with a Southern Hemisphere compass crossed the equator, would the compass immediately become useless? If so, at how many degress north does this error start? Link to comment Share on other sites More sharing options...
jakej Posted April 7, 2011 Share Posted April 7, 2011 IMO those that sell the Chinese instruments are doing their customers a disservice, maybe it's just about money - these instruments are quite often unreliable & should be banned from sale until the quality improves and there are approved maintenance manuals.

Brett, A remote compass is not enough. Quote from "Instruments required for flight under Visual Flight Rules" CAO 20.18 Appendix I 1 © (i) a direct reading magnetic compass; or (ii) a remote indicating compass and a standby direct reading magnetic compass rgmwa Link to comment Share on other sites More sharing options...
