Vertical Magnetic Compass
Whats the opinion of a vertical compass as compared to the whiskey compass? Do they bounce around a lot or are they stable like a DG?
I would like to mount it on the top of the instrument panel.

Here's mine:
The vertical card compass seems more stable than a whisky compass, and it's certainly easier to read.
Best Regards,
John

Darn! He's on to me!AR Dave wrote:OK John, you didn't use that as an excuse to show off that gorgeous instrument panel did you?
That, and I wanted to figure out how to include a photo in a message....
Thanks for the compliment!

Vertical Card Compass
I had one in my C-140, loved it. Put one in my 172-TD a few years back and wouldn't want to go back to the whiskey compass. Easier to read & it follows your turns as does the DG.
And ARDAVE beat me to the punch on John having an excuse to show off his panel. If my panel looked that good I'd put a photo (if I knew how) of mine on the forum!

An easy way to read a whiskey compass or AN gyro compass is to remember that if you want the numbers in the window to slide to the right....it's a right hand turn. (So if your present heading is 270 degrees and you want to fly 300 ...then you want that little number "30" to move to the right >>>>

That's a common complaint about the vertical card magnetic compasses.....they are fragile and unreliable. There's a service letter issued by the manufacturer (Precision) about installation procedures because so many of them are rendered inoperative merely by handling them during installation.
It seems to me that if the purpose of a magnetic compass is as an all-time reliable backup/primary instrument that we want to work when everything else fails.....then the vertical card version is a hazardous waste.

Wow! I didn't know these things had problems. I'll keep a suspicious eye on mine, and if it looks like it's acting up, I'll replace it with a whiskey bottle -- er, compass.gahorn wrote:That's a common complaint about the vertical card magnetic compasses.....they are fragile and unreliable.

Thanks for the heads-up, everyone!
