I?m pretty sure you need to push ?missed?. When you push ?execute? you lock in the settings. This is why: suppose you?re shooting an rnav(gps) approach, but it has an odd miss. Say, ?immediate right turn to 090, vectors to...?. Once you are established on the gps approach, and have pushed execute, you can go into the HXr?s menu, change mode to ?heading?, set the heading bug to 090, set the altitude to the missed approach altitude. Nothing will change, the box will continue on the gps approach. Until you push ?missed?. Then the autopilot will go to heading mode, will turn to 090, and climb to the set altitude. (You need to increase power).
