GeneralT001 Posted March 8, 2022 Report Share Posted March 8, 2022 I recently read, in another post, that someone placed a standby compass right in their panel as opposed to mounting it on the bar that runs on top of the instrument shroud. The more I think about that the more I like the idea. Aside from the obvious possible electromagnetic issues to its accuracy, is there any other reason to not do this (I understand you need the standby for VFR/IFR/Night)...but that little nuisance aside..... Can any standby compass with mounting holes be used? Say such as this one: Quote Link to comment Share on other sites More sharing options...
carusoam Posted March 8, 2022 Report Share Posted March 8, 2022 Back in the day panel space was extremely limited… not so much anymore. An electronic magnetic compass might be nice…. Best regards, -a- Quote Link to comment Share on other sites More sharing options...
GeneralT001 Posted March 8, 2022 Author Report Share Posted March 8, 2022 Btw...whats the big nut on the compass for? Quote Link to comment Share on other sites More sharing options...
carusoam Posted March 8, 2022 Report Share Posted March 8, 2022 Looks like access to where the fluid and air bubble are… https://www.airpathcompass.com/shop Pp guess only… -a- Quote Link to comment Share on other sites More sharing options...

Whoever worked on this compass last really did a number on that nut though Quote Link to comment Share on other sites More sharing options...

Best regards, -a- No. I already bought a brand new replacement compass (exact same one)...but am rethinking the whole mounting option and will probably return that one and get the panel mounted version instead: 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted March 9, 2022 Report Share Posted March 9, 2022 Many Mooneys got the panel mount one… Airpath shows many options that I didn’t ever know about… and options for the times the calibration isn’t strong enough… There are also degaussing conversations around here for the times your steel cage gets over magnetized… -a- 1 Quote Link to comment Share on other sites More sharing options...

N201MKTurbo Posted March 9, 2022 Report Share Posted March 9, 2022 BTW, that is your main compass. The one in panel (G5, KCS55) are not the ones that make you legal. Quote Link to comment Share on other sites More sharing options...

My understanding is it is the Standby Compass....required as a backup should your main compasses (the ones run off a flux valve or magnetometer failed)?

carusoam Posted March 9, 2022 Report Share Posted March 9, 2022 Rich, I didn’t know that… (at MS… I learn something new to me frequently…) There is another compass brand that is often selected stronger than Airpath… to mount on the vertical tube… In my O… I have an Airpath residing on the top side of the glare shield… nicely encased in a plastic cover to make it look finished…. I did use my compass once, as I was flying a circle trying to follow a failing HSI… Best regards, -a- Quote Link to comment Share on other sites More sharing options...
Yetti Posted March 9, 2022 Report Share Posted March 9, 2022 I carry a hiking compass as a backup. It is last in the chain of backups. One on the bar above the panel. Phone, tablet, Stratux. Dynon D10A Dynon VFR Only, Garmin 430W In ascending order. Quote Link to comment Share on other sites More sharing options...

The magnetic compass is required by regulation. The fancy ones you use every day are not required. The magnetic compass requires a compensation card. The fancy ones do not. That’s because you can always check them against the magnetic compass. Quote Link to comment Share on other sites More sharing options...
