"Hey first officer, since I'm hand flying, you think you could program up direct to fixxy for me?". Or you can't fly and program? Or put the A/P on, put direct fixxy in, then take it back off and go back to hand flying?You have an autopilot that can take verbal commands from ATC to change headings and then go direct to a point? I wasn't aware that existed.
If by autopilot fly the SID, you mean it can fly the initial turn, then fly the headings I input, then go direct to the fix after I input it, then yeah, the autopilot will do it. But it's not the "program it, click it on, and let it go" that a SID out of ATL is.
I'm not sure what your FMS can do, but ours also has a bearing pointer that I could have point at any fix. I could swing the old heading bug around so that the pointer matches the heading if I was handflying too...
There are like 7000 ways to do this in every airplane I've ever flown.
