AOPA Pilot - May 2013

AOPA Pilot


The press is taking notice of the new digital fuel level senders in the new Cirrus aircraft.


In this case AOPA Pilot and Tom Horne

Here the new fuel level  senders are being discussed with the integration to the standard Cirrus Garmin Perspective Panel.


We agree that accurate fuel level makes it much easier to manage fuel and payload 


The dialogue we started a year and a half ago 

That accurate fuel level in aviation will allow for a higher level of integration, and relieve pilot workload

These innovations are reaching the light of day and in now in production

Tank level balancing and enriched warnings are now reality

Beech Customer Responses

Beech Customer Responses

I have the CiES frequency senders, with matching Aerospace Logic gauges.

Working with Aerospace Logic requires patience, but in the end, the result is really spectacular.

Yesterday, at 8500 AGL, I ran both R&L Auxiliary tanks down to 0.0 gals, at 47:35 on the clock, precisely as expected... A few seconds later... Fuel pressure begins to fall, immediately switched back to left main.  

Accuracy... It's a totally new experience. I have two fuel totalizers. One Shadin and one in my G4.  Maybe having accurate fuel gauges is overkill... But it's an overkill that I like. 

The only caveat is that my shop wasn't particularly efficient with the remove / reinstall / remove / final install / calibrate process.   I have ALOT of money tied up in this.   
But I don't regret it, and I would do it again. 







For anyone who is considering CiES fuel senders these things are awesome. They are well worth the work to install. I ran all new shielded conductor up to the back of my JPI 930. Finally I have a reliable and consistent fuel measurement in my airplane. 

Wow, who would have thought accurate fuel level was possible.

If your airplane is down for an upgrade I would send your old fuel senders to CiES.   This will insure that the senders are appropriately set up the first time.   Beech in all their wisdom made numerous different senders inverting the bolt patterns on some etc. 


CiES senders can work by resistance, voltage or frequency. I would chose at a minimum voltage if you can, Frequency is even better.
Scott @ CiES knows his stuff.



----------------------------------------
The cost to retrofit CiES senders to a pre-74 B55 is around $3200 (plus installation). That may seem "outrageous" but it's only about 50% more than what it costs to have the eight (2 per tank * 4 tanks) senders "overhauled" and my experience with overhauled senders is not very good. At best the overhauled senders will perform as good as when new for a few years which is to say they're accurate to within about +/- 5 gallons.

Properly calibrated the CiES senders appear to be within one gallon.  In a Bonanza with two 40 gallon tanks or a post 1973 Baron there are only four senders so that cost is cut in half.

 IIRC the last time I checked, new (1940s technology based) senders from Beech were around $1,600 each or over four times what CiES charges.

-----------------------------

+1 on the CiES/ Scott Philiben Phan club. There's no better customer service than that provided by Scott. anywhere.

I'm still VERY happy with my CiES senders. You know, when something "just works", you take it for granted.   I don't really give my CiES senders much thought. 


They're underappreciated little heros quietly doing their job. Perfectly. All the time.

A New Day has Dawned in Aviation

General Aviation News Photo



“Getting this STC done has created the roadmap for us to continue on,” said Pelton, noting that other STCs may involve fuel systems, autopilots and more."  General Aviation News 


We have made great strides in replacing legacy fuel quantity indication in GA aircraft and Jack Pelton's comment above, indicates the importance of improved fuel quantity indication in the roadmap to improving the equipment on legacy GA Aircraft.    

Today's EAA STC news announcement opens up the literal Pandora's box of opportunity.

Actually our FAA TSO approval allows us to move even faster into getting universal approval for installing better fuel quantity systems in GA aircraft.  

The TSO approval insures that we have met both the new ASTM standard for Verification of Avionic Systems but also the RTCA DO-254 Design Assurance Guidance for Airborne Hardware as well as the DO-160 standard for surviving the external environmental conditions found on the wing of the aircraft 

This is a major step forward and was not anticipated after the Part 23 Rewrite NPRM.  

The new ASTM Standard makes it much easier to show compliance with organization, definition &  verification of our software.   

Utilizing a smart sensor was key to CiES obtaining the outstanding aviation fuel level sensing results.  

This quality indication is one that thousands of pilots rely on,  flying brand new Cirrus, Vulcanair, & Quest aircraft.  

Contact CiES as we are adding fuel quantity sensor configurations for thousands of single engine and twin aircraft.

That may seem "outrageous" but it's only about 50% more than what it costs to have the eight (2 per tank * 4 tanks) senders "overhauled" and my experience with overhauled senders is not very good. At best the OH senders will perform as good as when new for a few years which is to say they're accurate to within about +/- 5 gallons.

I'm having a hard time seeing anything "outrageous" with CIES pricing.

---------

And one additional point about CIES senders. I have absolutely no doubt if any question or issue came up, Scott would be on the phone within the hour. (More likely in minutes.) Every interaction I have had with him and interactions I have seen others have with him have been very positive. 

Phone or email he's always been very helpful.

Piper PA-31 Navajo Fuel Quantity Senders

Piper Navajo Fuel Quantity Senders  


We just completed a set of Piper Navajo senders for Mike Jones Aircraft.   

We replaced the old resistance sender design with the CiES Magnetic Field design .  Like a lot of well regarded aircraft, the Piper Navajo has not been supported by the factory for some time and the existing replacement senders either don't work or they have outlived their ability to be effectively re-worked along.
The CiES fuel level sender is built for the Navajo application, with a custom arms dedicated to each location on both the main and the auxiliary tanks.  Our non-contact fuel quantity measurement method insures that leakage can not happen through the sender body.  A modern digital sender component to compliment a modern digital cockpit interface, like a JPI or Aerospace Logic.

All of our sensor electronics are fully enclosed in the aluminum housing.  Unlike traditional failure prone senders - our senders have amassed an impressive record of 350,000 hrs of flight time without error or in service replacement.   

We will change your opinion of what float fuel senders are capable of - both from a precision and reliability standpoint.

Finally a fuel level sender specifically designed for the aviation market.

Vulcanair P68 Service Bulletin - Digital Fuel Level Digital Fuel Level

Vulcanair P68 Service Bulletin - 


The two new fuel senders are of magnetic field typology and their output is a digital square wave signal whose frequency changes according to the fuel level in the tank.

This new fuel sender uses one wire to interface the level indicator by which it transfers its output frequency to the indicator and a second wire to get a voltage supply, typically  the 28Vdc of the aircraft.


Vulcanair is the second OEM Aircraft manufacturer to utilize the CiES Digital Fuel quantity sender for installation on all of it's aircraft.   

Vulcanair is the first manufacturer to offer a retrofit Service Bulletin Kit to install the system on legacy Vulcanair and Partenavia Aircraft.
