* For the HDG/NAV mode it is important to calibrate the [[HSI]] to the magnetic compass (with running motor, so the HSI has power): read the magnetic compass and rotate the HSI so its upper bearing mark reflects that course (use the red heading bug if necessary, it makes it easier at the beginning). If your HSI was not calibrated, this will not be the magnetic course and you probably will not get where you wanted to.

* For the ALT mode it is important to calibrate the barometric setting of the autopilot to the one of the altimeter: read the altimeters baro setting from the Kolsman window (the small window at the altimeter), press the "BARO" key at the autopilot and rotate the right "altitude-preselect knob" so the autopilot shows the same setting. If you miss to calibrate the baro setting, you will under-/overshoot altitude presets.

* If you intend to follow the runway heading after takeoff, now is a good time to adjust the heading bug.

* If you intend to climb to a specific altitude and let the autopilot intercept it, you should now rotate the altitude preselect knob of the autopilot to the desired altitude.
