installations hitting the Go-Around (GA) button (if you have one) disen- gages the autopilot but moves the flight director command bars to a wings level (roll control) 7° nose up attitude (attitude mode). The pilot manually flies to match this optimal initial guidance. It’s then an easy two- button task (HDG and AP) to put the autopilot in these modes and confirm they’re working.
Now that the autopilot is on, deal with the navigation of the missed ap- proach procedure, including whether or when to exit GPS Suspend mode. When you’ve exited Suspend mode as applicable and have confirmed the navigation is set for the missed, stay in HDG if your GPSS requires, or turn on NAV if it doesn’t (or you don’t have GPSS). Then set your altitude preselect if you have one and have not already done so.
If you don’t have the GA feature, a go-around would begin with deac- tivating the autopilot and beginning a straight-ahead climb—again, wings level and 7° nose up in most cases.

Hit HDG and AP and the autopilot en- gages on your current heading at your current pitch attitude. Do all the navi- gation tasks and transition to more complex autopilot modes afterward.
Some of the most recently cer- tificated autopilots, including the Garmin GFC600 now approved for many light twins and turbines, include
the GA feature with a significant dif- ference: Engaging GA mode does not shut off the autopilot. It does, however, move the f light director command bars to a straight-head, 7° nose up at- titude—defaulting to the simple roll control and attitude modes—then automatically f lying the airplane to that guidance. From there it’s up to
