Russ ________________________________ Message 2 _____________________________________ Time: 04:59:19 PM PST US Subject: Yak-List: Gyro compass adjustment From: "Looigi" Hi All, We have just imported a Yak-52 into New Zealand from Italy. He is almost ready for flight, but one job that remains is to do a compass swing. Our plane has had the ADF system removed. I am not sure if that affects things; I know the systems are sort of tied together. The direct reading compasses are easy, but does anyone have any data on how to adjust the gyro compass? I have flicked the switch on the control panel to "South" and set the lattitude, but I am thinking I will need to fiddle with it to sort the deviation.

First thing is find the compass. Most likely in the aft fuselage - remote from electrical interference as much as possible. It has a corrector unit like the standby compass and is swung in the same manner but has an additional feature. Once the standard swing is complete calculate the average algebraic sum of the corrections (+ or -), unlock and rotate the entire compass in the correct direction to remove that error.
