I have waited, vented, and now I must go public. I will say this as loudly and publicly as possible:
DO NOT BUY THE ARNAV ENGINE MONITORING UNTIL IT IS DEBUGGED BY ARNAV, HAS CORRECT INSTALLATION INSTRUCTIONS AND AN OWNERÂ’S MANUAL THAT IS EVEN MODERATELY INFORMATIVE!
Sorry, but ARNAV has to learn that for the most part, we are PILOTS, not engineers. We want to fly our planes safely and efficiently, not spend hours learning an incomplete system while, without compensation, helping the company debug and perfect itÂ’s products which it is selling. If you buy this product now, you are a beta tester.
Here are just a few examples:
ARNAVÂ’s OwnerÂ’s Manual (OM) includes pictures but absolutely no discussion of the symbology.
Other than a few secondary functions, there is no discussion of how to use any of the features.
The installation, which is clearly marked for the SR20 and SR22, is really for the SR20. It does not even acknowledge the presence Sandel EHIS which is an important component.
It does not even mention a change to the accuracy of the stock CHT gauge.
They updated the display (windows style buttons) but there is absolutely no discussion of any changes.
They have a “fuel required to next waypoint” in two places and they disagree.
Our only leverage is the power of the pocketbook. Installed, this product costs about twice what the competition does, and except for some minor features, is inferior. One of the main reasons I purchased it is that CirrusÂ’s vision and design of the SRÂ’s leaves minimal panel space available for additional instrumentation. I was willing to pay a little to follow this vision and not hack up my panel.
Cirrus is not to blame for this product, but they do have to make some strategic decisions soon. In my opinion these are:
Do we stick with our vision of the landscape 10" display even if there are no products on the market which meet our requirements?
Shall we continue to sell our aircraft with an inferior product which is poorly supported by a company which will has to date, and may continue to, reflect poorly on own products and us as a company?
What do we owe our existing customers who have bought these aircraft, at least in part, because of wheat we, Cirrus, have promised and essentially failed to deliver?
I have posted this as a challenge, primarily for ARNAV, but also for Cirrus. I will talk to ARNAV early in the week, and give them a chance to fix the situation. Either way, I will continue to post my experiences.
Until, then, I strongly recommend that you wait for a purchase of an engine monitoring system. If you cannot wait and are not interested in helping ARNAV debug their system, PLEASE do not buy the ARNAV system.
Hopefully, I will eat these words. There is nothing I would rather do than print a retraction as it would mean I am happy with my purchase.
