I'm a little frustrated with the Carenado da62.  I'm flying a procedure turn to intercept an ILS course.  Everything is tuned and identified.  I have descended to the approach altitude, for the ILS 12 at KBZN that is 8100 ft.  I fly outbound and reach the procedure turn point to turn inbound, execute the turn and set up the localizer intercept.  I am on heading mode because the G1000 has really messed up procedure turns.  Once close to the intercept I switch from heading mode to approach mode.  The aircraft is of course below the glidepath as I have not reached the descent point.  Yet when approach mode is engaged the aircraft starts to climb in an attempt to reach the glidepath.  Why in the world is it doing this?  Is there any way to stop it from doing this?

I just tried another ILS approach KDEN ILS 34R.  Took off from 34, heading mode, vs to 7000 ft autopilot on.  Used heading to turn crosswind, then downwind, and base.  Configured with gear and slowed the aircraft.  Used heading to set up the localizer intercept.  Altitude hold on at 7000 ft.  Changed over to approach mode.  On intercepting the localizer the aircraft again started to climb to intercept the glidepath.  This is really messed up.

Ok I found out what I was doing wrong.  I'll have to check this out in the other two version of the da62 that I have.  So for anyone interested, or trying to learn to fly this aircraft here was my mistake.  On downwind I waited for the glideslope to move to the top of the indicator.  I then changed the heading bug to an intercept heading for the localizer.  I then switched the autopilot over to approach mode.  Doing this kicked off the altitude hold, hence the aircraft climbing.  The correct procedure in this aircraft is to switch from heading mode to nav mode.  Then once the localizer is engaged switch over to approach mode.   So I guess I just forgot the basics and needed this as a reminder of the correct way to switch autopilot modes.
