Subject: 540 doesn't sequence during SID

OK I've been playing with the simulator and I was wrong about one thing. You CAN select a waypoint in the flight plan and hit the activate leg LSK which will give you guidance along the published course to that waypoint, not direct to guidance. So that's good for a SID where you want to skip the runway heading and intercept heading waypoints which may or may not prompt you to sequence (they didn't for me 2 of 3 times). That's an acceptable work around for a SID where you can make that selection on the ground. But in the missed approach scenario where you are close to the ground, trying to reconfigure the aircraft for climb, turning to a heading, and maintaining control it is unacceptable to have to twist knobs and push buttons. At least on my old 430 it was just one button push (SUSP). I get Avidyne's reasoning and desire to provide positive GPS guidance along all phases of flight, even headings. That works great for an integrated system like R9 where you always have baro corrected altitude data to the GPS. But in a retrofit situation where most people do not have this feature it just adds complexity and workload. It would be nice if there were a user selectable option to turn off all runway and intercept guidance waypoints.
