One annoying thing... anyone notice that the Yaw damper sometimes continually kicks off? It happens to me sometimes and it seems maybe related to putting the batteries on too soon. If you throw on the standby buss and don't wait for green terrain on the bottom screen before you turn on bat1 and bat2. at least that's my theory.

Has never happened to me 1 time.

There used to be a lot of yaw damp issues which I think were cured with new Builds. Do you have an old Build?

I reported smooth at 450 and heard, “Would you rather be up there where the air is smooth or down here where the money is?”

Zero YD issues on legacies (Series 9/10) so far.

Adam,
I’ve seen strange rudder trim and YD issues when starting before the YD CAS and Autopilot CAS (Cyan/Advisory) messages have cleared. If I wait until those have cleared before pushing start, all is well. Another instance when I have had issues with the YD is if the nose wheel is cocked or someone is pushing on the rudder pedals when the apex is booting and going through all the AP checks. It seems if the apex has a clean boot, it is rock solid afterwards.

Yes. The quirks of the system at startup are silly so I take my time.

I turn on StandBy Bus then I go take the covers off the plane and get a cup of coffee. Go back to the plane and load the flight plan and weights (nonsense) enter enter enter and then I Arm the EPS. I go get a refill of coffee. Once the Backup HSI is fully loaded and past is "ALIGNING" stage then I turn on BAT1 and BAT2.... then GPU.

Here's another quirk I found in the earlier Builds with regards to YAW DAMP issues...... If you are going to do any hard banking after takeoff or hard nose high attitudes after takeoff, do NOT arm the Yaw Dampener until after you are done. In other words, don't arm the Yaw Damp until you are climbing at a reasonable speed in a straight line.

The only thing about the Honeywell I don't like is the startup procedure. In Garmin planes you just turn on the batteries and go. Whatever you DIRECT TO to IS your destination. For some reason the Honeywell separates "where you want to go" from "what your destination is"..... It's odd logic.

Wow thats a bummer, in the TBM I flip the switches and about a minute and its ready to go, faster than I can do my checklist. I hear the NXi is even faster. I have use a gpu once in 6 years of flying TBMs and it was a pita.

GPU has nothing to do with anything on the Pilatus. You don't need to use a GPU. I just choose to for engine health.

The Honeywell on the other hand might as well run on coal.

I know that earlier PC12's had an issue with the servos that affected the yaw damper. I'd check with Epps (speak with Greg Allen) and he'll give you the skinny.

My boot sequence is different that Crandalls. My non GPU start sequence in the heat is as follows. I preflight everything INCLUDING the start, without switching on the switches.

Then I switch on the standby, start loading people, third person in, once I have dirt showing on the 3rd screen, then I test the EPS, then turn on both batteries. Finish loading the folks and close the door.

IF it's just my family and it's ONLY the kids AND they've been misbehaved I let them sweat it out a little.......you should hear the little buggers complaining

IF my boss (Char) is on the airplane, I close up as soon as the last person is on, start up and get the AC flowing........

My boot sequence is less than 2 minutes total.

I load my destination field (less than 30 seconds max) and then call up clearance.........normally my departures are fairly simple, and even if they are not, they're easy to put into the APEX (IMHO).........

In 400hrs last year of flying I used a GPU twice.............I'm always on batteries.......I have the nicads.

Curious, if available, would you guys upgrade to the G1000NXi for $400k and what do you think of the IS&S panel in the legacy airplanes?

Hell no. I like the Honeywell. The boot-up procedure is just a little slow.

Denali will have Garmin so Honeywell is going to need to up their game. The question is.... can they? I think avionics are the number 1 selling point on airplanes.

But no.... I wouldn't spend a penny to rip out all the Honeywell. I don't even think about avionics anymore. All I need is a glide slope.

The whole airplane is Honeywell.... It's not just the panel.

If I don't allow the backup HSI to finish loading before I switch on batteries I get weird CAS messages.

Do you startup the motor with ACS inhibited?

Me too. That's another little "oddity" but at the same time I'm glad you have the option to start up with a lighter load on the system.
