Aspen EFD1000 - keep VSI?

[JoeM]

Aspen says their EFD1000 Pro doesn't require keeping VSI, but I see the legacy instrument in some installations. Do those who fly with Aspen recommend keeping the steam VSI or does the Aspen show this well?

I had one with vsi removed and really missed it.  I, d keep it, especially if you have flying actual with one. The vsi depiction on the aspen is small and hard to pick up in a quick glance.

Sooo, I’ve thought about this one a lot. I also still have my old VSI with the MAX PFD.  Over the last few years I’ve tried to focus on the Aspen VSI to prep myself if I eventually add an MFD because I’d probably keep my airspeed and altitude indicator.  I’ve learned to use the VSI tape on the HSI because it tends to show trends like the VSI gauge and I don’t seem to chase the VSI as if I just used the magenta VSI on he altitude tape which I agree is too small.  You have to switch out of ARC mode to HSI if you have an en route climb or descent but not a big deal.  In the end…I’ll probably keep things as they are and probably go to a GTN-750 for the display real estate and not do an MFD and keep the VSI gauge.

My panel was very nicely equipped, and included MAX Aspens, when I bought the plane.  I previously had a Mooney with steam gauges.  I had no problem using the Aspen-only display VSI.  I wear bifocals or readers in flight, and that may make a difference.  In the end, it will be about preferences, and if you have a choice at all.  I did not, and it worked out great.

I'm in the same camp as @gacoon.  Previously I flew a C with a six pack.  When we purchased our J, it was equipped with an Aspen and INOP TC.  I found that the TC readout on the Aspen is ok, but the VSI  didn't suit me.  Its dynamics were not as smooth as a steam gauge VSI, particularly in turbulence.  Rather than replace the TC, I decided to replace it with an analog VSI.  It helps me more effectively manage energy on approaches with less mental energy spent understanding vertical speed compared to the Aspen.  Easier stabilized approaches.

With the installation of my Aspen, my VSI was removed to declutter the panel. I never missed the steam instrument. The Aspen VSI works fine, no problems.
