hubcap Posted May 27 Report Posted May 27 I just got my invoice for the IFR certification that is required every 2 years. I was wondering how much folks are paying for that service. My invoice was for $634.38 which includes the certification for my 2nd altimeter on the G5. Quote
wombat Posted May 27 Report Posted May 27 I had mine done last month. 3 altimeters, $550. They also updated the software on all my Garmin stuff for $187.50 Quote
MikeOH Posted May 27 Report Posted May 27 $400 last August. One altimeter, transponder/encoder, and static system, with certs/logbook entry, tax, license, dealer-prep, and options 2 Quote
pkellercfii Posted May 27 Report Posted May 27 $400 last fall. That was for FOUR altimeters (Aspen 2000 system + L-3 ESI 500 backup PFD + OEM mechanical altimeter), plus everything else that goes with transponder and IFR checks. Shops have varied on how they treat my multiple altimeters. Some charge more for multiple altimeters, so don’t. Last year’s shop didn’t charge extra for multiple altimeters. Per the FARs, all altimeters must be checked for the IFR checks, although so far that’s just meant that the shops have to record the readings from all altimeters. One guess as to which altimeter was most accurate… —Paul Keller Quote

That does not include Garmin G5s, the G5 instrument is not certified for use as a primary altimeter (which makes the fact you can run a GFC500 from it a curious quirk). The GI-275 is certified primary, not sure about Aspen and L3 systems. That said, if you own G5s, you may wish to pay the shop to calibrate them anyway, just to avoid the annoyance of having multiple altimeters in your airplane read substantially different. It's been my experience across about a half dozen different data points, that an uncalibrated G5 altimeter will read 50-100' high vs. field elevation, at least at the 5000-ish foot altitudes of the local airports where I fly. This error is in the "dangerous" direction, and on a precision approach, it could result in you descending as much as 100' below minimums. Quote
N201MKTurbo Posted May 27 Report Posted May 27 My Square D and G5 altimeters differ by less than 10 feet at all altitudes up to 25000 ft. Except at 17000, the Square D is off by 40 feet. It must have a burr on its gear. My G5 is an HSI, but I flip it to AI mode when they do the checks just to see how it does. My encoder is only a 100 ft encoder, so I can’t tell if it is within 10 feet or not. Quote
0TreeLemur Posted May 30 Report Posted May 30 $450 earlier this month for two altimeters and one encoder. Quote

Precision Static Testing in Livermore. They travel to the local airports around NORCAL which is convenient. $325 in Mar 2024, for the IFR check on two altimeters. $125 last Jan for a VFR check after I had to swap out my xpnder. Quote
