This page contains information about the 1968 Piper Arrow N7430J that I used to own. It probably doesn’t make very interesting reading unless you are interested in flying. If you are looking for pictures, you will find them here. If you are looking for stories about flying, click on the Aviation category in the right hand column.

Operational Notes

Weight & Balance — Here is a spreadsheet with a sample loading problem and the corners of the CG envelope, in both Adobe Acrobat and OpenOffice.org formats: weight and balance.pdf | weight and balance.ods.

Autopilot — When using the autopilot in GPS nav mode, set the CDI scale factor to 1.0 mile by pressing CRSR on the KLN 94′s NAV 1 page. The autopilot sometimes allows the plane to “wander” almost a full dot left or right of course, which is almost a full mile at the default scale factor of 5.0 miles. It tracks with a scale factor of 0.3 miles but oscillates and I have doubts that will ever settle down. With the scale factor set to 1.0 miles, the plane generally settles down within 0.2 miles of the course and holds nicely. Turning the wing-leveller knob adjusts how far off center of the course the plane flies.
