So I'm familiar with what you can and can't do with the published and unpublished holding features built into the IFD, but I'm curious to hear what the steps are that people take to actually fly these holds once their added to your flight plan.

The reason I ask is that I came from flying Garmin GTN equipped planes, and the GTN walks you through each turn pretty clearly, with a countdown prior to the turn, etc.  The IFD just gives you a mess of colored lines to decipher, and some cryptic messages that aren't immediately helpful without some thought ("exiting hold at fix" can be alarming to see right as you're entering a hold and expecting some guidance).  So as a thought exercise, I'm curious if anyone would be willing to post a step by step of how they enter and fly an FMS hold, specifically covering the following:

-How you plan your entry
-How you determine when to begin each turn
-What guidance you follow on the inbound leg
-What guidance you follow on the outbound leg
-What reference you use (datablock, external DME, etc.) for flying holds with distance legs instead of timed legs

I know how I fly the holds, but I'm curious to hear how others do it.  Thanks! :)

I guess everybody just kicks on GPSS and lets the DFC90 do the thinking? :)

I have only flown holds one three or four occasions, and haven't done it recently, so I can't sit here and tell you what I did.  But I don't recall thinking that it was confusing or unintuitive.

I have flown them by hand and with my GPSS single-axis autopilot engaged.  I didn't have trouble either way.

Real HOLDs are infrequent, but with the IFD and an A/P they are mundane. Not much to think about.

When I had my 430, years ago, it wasn't that much of an issue either. I would fly a heading to make good on the outbound, and just OBS in to the fix on the inbound.

If flown manually, for HOLD entries, I will use a parallel or direct only. That way you don't have to think about which way to turn passing the fix (parallel vice teardrop), it is either straight outbound on the radial, or you have just entered the HOLD already on the inbound.

One thing for sure; if you get great tailwinds you’re going to get to hold.

If you are on a published hold, the IFD will tell you the type of entry, countdown to turns as well as heading to turn to in the lower right corner
