# ''Small adjustments'' can be made by pressing just the UP/DN buttons.

Recent KAP140 simulations implement this.</ref> Note that we are in ALT mode, so we adjust absolute altiutde with UP/DN knobs, not climb rate! | ||
# For ''larger adjustments'' you just rotate the altitude preselect knob to the new desired altitude. The autopilot will show "ALT ARM". When you are ready to climb or descend, put the autopilot to VS mode by pressing the ALT button. Now push UP/DN buttons to climb or descend, and everything else will behave like already described above. You can adjust the desired climb rate anytime. When intercepting, the autopilot will automatically enter ALT mode again (which changes the behaviour of UP/DN buttons to absolute corrections too!). | # For ''larger adjustments'' you just rotate the altitude preselect knob to the new desired altitude.

# For other cases you can also use the manual ALT mode: Put the autopilot in VS mode by pressing "ALT", adjust the climb rate to your liking and as soon as you feel the altitude is right, you can press "ALT" again. The AP will show "ALT" immediately, indicating it is holding this altitude. If your climb rate was a little higher, you probably overshoot the desired altitude, but the autopilot will soon return to it. | # For other cases you can also use the manual ALT mode: Put the autopilot in VS mode by pressing "ALT", adjust the climb rate to your liking and as soon as you feel the altitude is right, you can press "ALT" again.
