True Mike very true, unless

You have a total short whilst in cloud that fry's everything else.

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.

Just SAYIN

Obsolete instrument mandated by the Regulator. In gliders mainly used to fill

In high wing powered aircraft can be used as attach point for pair of fluffy 
dice which are about as useful.

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).

Regards,

Tom

Hi sailplane drivers.

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

Many thanks
