Subject: Re: [Aus-soaring] Compass Swinging I think we are talking about day VFR here, Justin. I've got 4 GPS units in the BD-4,all with their own internal battery backup. I'm a fan of "train like you will fly, fly like you trained." In 2015 the answer to a GPS failure is another GPS. If the entire satellite constellation fails, the human race has got other problems and your little navigation problem pales into insignificance. Yes, Chris, it is a requirement to put a new glider on the register. It still is a stupid requirement in 2015. Like many rules in aviation, it isn't there for your or my benefit. It is there to provide arse cover for the people making the rules so they can continue to collect their pay. At very least the rule should be a magnetic compass is required unless the glider has two GPS units and batteries or at least one GPS has internal battery backup.

I that case you are going to thank Christ (or what ever your mythical friend is ) your old instructor taught you ONUS. Unless you have a AHARS GPS the update rate is way to slow to fly limited panel on.

In gliders mainly used to fill instrument hole that could be used for something useful. In high wing powered aircraft can be used as attach point for pair of fluffy dice which are about as useful.

Subject: Re: [Aus-soaring] Compass Swinging Hi Chris, There are a few methods but the easiest is as follows... 1. Using a master compass (a good bush walking compass will do) align the glider North South. (This should be done well away from any hangars with power on and instruments running) Using a non magnetic screwdriver, adjust the compass to North. 2. Align the glider to South using the master compass and halve the error. 3. Repeat in East West. 4. Align the glider to all the cardinal headings (ie, every 30 degrees) and record the indicated heading. 5. Complete the correction card. Using this method you should be able to get to within 2 degrees on every heading (not always but usually).

Has any one got a procedure for swinging glider compasses, or a link to a web article would be good?
