I thing "heading" is default so you just push and hold to sync the bug. If you would select altitude you can sync the same way.So if my AP is following a flight plan in NAV mode on my 530 and am given a vector by ATC to divert around airspace, and to avoid a radical change in heading when switching to HDG mode on the AP , I should use the right knob to select HDG on the Aspen and then press and hold the knob to sync with the current heading?
Yes, but I go a step further. Your heading bug should always be synced with your course. In NAV/GPSS mode, every time you change course you should be either (a) turning the heading bug to the new course in anticipation of the change or (b) syncing the heading bug immediately after the change. This is not Aspen-specific. It's part of staying ahead of the airplane and being prepared for the AP to do something unexpected.So if my AP is following a flight plan in NAV mode on my 530 and am given a vector by ATC to divert around airspace, and to avoid a radical change in heading when switching to HDG mode on the AP , I should use the right knob to select HDG on the Aspen and then press and hold the knob to sync with the current heading?
Syncing to current is one of those things that has become standard in the PFD/eHSI world. Aspen, Garmin, Dynon… they all have it. Across multiple functions.Wow, I’ve flow 400 hours behind an Aspen PFD and never realized that’s what the “Sync” could do, I was always turning the heading knob manually.
Learned something new from PoA today !
