Aspen Altitude Aural alert

[PeytonM]

I have the Aspen PFD1000 and wondered if it's worthwhile having the aural altitude alerter. Can you hear it with noise-cancelling headsets? What type of Sonalert do you have? Can you wire it through the audio panel so you hear it directly in the headset? Thank you for your input.

I don't know what type of a sonalert, but I definitely hear it with noise canceling headsets.  Mine isn't wired to the headsets.  It's surprisingly loud.

I have the altitude alert on the Aspen for altitude preselected and for DH on approaches. Works fine without it being wired into the audio panel.

For those wondering what the altitude select looks like on an Aspen. It begins beeping within 200 of the target altitude.

I will agree with Jrwislon on this one. I have a pair of Bose A20's and I can hear the aural alert during all phases of flight with the noise cancelling turned on. Most importantly, I hear it when I hit my minimums/DA on precision approaches. DEFINITELY a nice upgrade! Mine doesn't seem to like the cold weather though, as the beeps seem slower but still activate when 200ft above or below. On a side note, does anybody know how the HSI initializes your heading? Is it via a flux gate or coupled to the GPS somehow? I can't seem to find the answer to this question anywhere!

Aspen uses a RSM module that looks like a GPS antenna, that gives it attitude info, temp and GPS. It typically is located behind the baggage door on the pilots side of the fuselage,

The magnetic heading info comes from the RSM as well.

Marauder you come through once again! I should've known to look at the antenna in the book. Guess I must have missed that one. I've been busy studying for my instrument check ride and I wanted to have the correct answer for my examiner next week. Thanks again!

Good luck on the check ride. It is a fun rating.

What do you have to do to have the feature turned on?

You need the physical alarm installed. I think by default it is a feature that is turned on.
