CiES Inc Update

If we reflect on the past year we have accomplished quite a bit

  • Secured a OEM contract on the most produced General Aviation Aircraft  - Cirrus SR20 & SR22.
  • Obtained a TSO for producing this fuel level sender applicable to all aircraft.
  • Received retrofit approval to install our TSO sender on all legacy Cirrus Aircraft. 
  • Designed an LPG (propane) level sensor with iPhone/iPad interface
  • Initiated OEM installation on the Gippsland GA-10 Turboprop, Discovery 201 & Vulcanair P68 Aircraft series.

  • Achieved aircraft industry recognition for our accomplishments
What is now happening behind the scenes is truly impressive 
  • Engaged in engineering design with several manufacturers for installation of our fuel level sensors on their aircraft platforms.
  • Working three new aircraft platforms 
  • Involved in several STC retrofit applications 
  • Finalizing the boat level sensor to display at a major customer

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

Flying Magazine - May 2013

Flying Magazine

Well we have been waiting for this -

Recognition in the press from actually editorial resulting from a flight utilizing   our fuel level sending technology.

When reading about all the very significant changes made for the new 2013 G5 Cirrus.  You see the mention of accurate fuel level - not once but three times 

In the article there is an extensive discussion about the fuel imbalance messages being determined by fuel level.

Not the Fuel Totalizer - the Fuel Level 

If you pay close attention -  the differential they are talking about is an accurate reading of a level of fuel at 10 gallons between the two wing tanks and then at 12 gallons. 

Yes -- our senders give levels of accuracy in the 46 gallon tank of less than  two gallons.




















Again in the side bar - a mention of not just accurate - but highly accurate fuel level.

I

Imagine an editorial in General Aviation magazine - praising the quality of the fuel indication.

Not Fuel Totalizer -
The Fuel gauges

And finally in the specification banner another mention of the electronic fuel level sending units.


While we strive every day to change fuel level sending in aviation with better technology, quality assembly 
and attention to detail 

We are very proud that our efforts are being recognized

Fuel Starvation - The Bucket List

NTSB  --   Safety Alert


The NTSB continues to take a close look at General Aviation Safety

One topic fails to be actively discussed....... Fuel Starvation/Exhaustion Incidents in General Aviation Average 2 to 3 per week and in the Top 5 of all causes.   While this is an issue for aviation safety,  it receives scant mention in the NTSB reports or in mitigation strategies.

This is not an uncommon or a glaring oversight,  most pilots, which some of the NTSB board are, will quickly point the blame at a fellow pilot for this particular accident scenario.

In this quick rush, I believe we are overlooking contributing elements in the chain of events that contribute to incidents and accidents of this type

General Aviation Safety: Climbing to the Next Level

In the NTSB Chairwoman's presentation at Oshkosh Airventure.

Aero News Network reported the following:

"Hersman said that while private flying accounts for only about half of all the flying done in the U.S., it accounts for a disproportionate number of fatal accidents, according to a study done by the NTSB. She said there are some themes that seem to crop up in many GA accident investigations that could be addressed by better pilot training and pre-flight planning. "I think that there are things that should never happen, really the easy things, and then I think there are things that are hard things, too," Hersman said. "And I think that among the things in the bucket that are easy ... fuel starvation. How many times do our investigators need to investigate an accident like that."

Press Coverage of NTSB Chairperson Barbara Hersman


I disagree with the NTSB chairpersons Barbara Hersman's response,  I believe this is one area that needs a detailed and closer look.

Fuel Starvation / Exhaustion as reported above is a common occurrence in aviation - 
The chairpersons comment in her News presentation in Oshkosh suggested that an NTSB in-depth evaluation into the causal factors of fuel starvation is not warranted by the board.

In the board GA Safety Board Meeting and the recent NTSB GA Safety Alert  - Fuel starvation was only lightly addressed there was really no mention of fuel related issues.  

I want to ask  .....  Why

Yes the unfortunate pilots that have experienced fuel starvation or exhaustion should have known how much fuel they started with, the should have checked prior to flight.  and they should have known average fuel consumption - his "maths" – Basic Pilot Skills.  Inculcated from his first training flight  

But the headline to the right says a lot about the information available to the pilot about their fuel level.

Accurate & Reliable Fuel Level in Aircraft - Is the Exception & Not the Rule. 

And in an emergency situation every pilot should know which tank has the most fuel – they need to know which tank to switch to.
Every pilot manual states that for the most engine critical procedures – Take off – Engine restart – Engine performance (spitting coughing) – switching to the fullest tank is not only required, it will save you from an incident.

If Ms. Hersman would have asked the aircraft owners in attendance at Oshkosh if they had accurate fuel level gauges – the response to that inquiry would be startling.   Accurate and reliable fuel gauges are the exception in small aircraft and not the rule.

In fact some pilots in attendance will state clearly they have accurate gauges in their aircraft as the gauge will read zero when they are out of fuel.    What they won't say is that the gauge reads zero all the time.
How can you make the determination of your available fuel or which tank had greater quantity of fuel if your gauges are erratic or of limited accuracy and why are we turning a blind eye to this in aviation.
This fundamental issue becomes very real when you read the NTSB Accident Investigation Reports that resulted from fuel starvation occurrences.   In most every cace where there was still fuel onboard the aircraft - the selector was on the dry tank -.

When almost every learning GA pilot is told not to trust the fuel level gauges – are we in aviation really surprised that fuel exhaustion occurs so often, or that a solution would fall into the "EASYbucket

If technology in the form of Angle of Attack systems are indicated to help Stall Spin incidents

I am baffled why fuel level technology gets the literal  short stick.

Cirrus SR22 Avidyne G2 and 6 Pack Retrofit

We are installing the first Cirrus SR22 G2 (And G1) Retrofit sender at Professional Air In Bend, Oregon.

The new sender designs were patterned after the existing unit in the aircraft.

The new sensor utilizes our patented technology found in the latest generation Cirrus aircraft.  Additionally our sensor did not require the steady bracket seen in the upper left.

If you ever have to remove a sensor to replace a gasket for example.  The access panel will not have to be opened.

We expect to have the aircraft buttoned up early next week and ready for calibration.   

Working hard to rapidly grow our customer base.

Cirrus Aircraft Factory Fuel Level


We have been supplying Cirrus Aircraft fuel level senders for over a year.  There have been no issues or in-field replacements.  Now that the senders have proven themselves day in and day out and showing excellent reliability and repeatability.  We can now start to exploit the advantages accurate fuel level can provide.   

In the Cirrus Aircraft Facebook post yesterday - one of these new features came to light.  

Cirrus wrote the following:

Since spring of last year, our aircraft have come equipped with fuel level sensors that read accurately at all levels. In fact, they are so accurate that we were able to integrate a fuel imbalance message on the PFD in Generation 5 aircraft. The fuel level sensors in most of our competitors’ planes only read accurately when the fuel tank is empty or full. For more on the astonishing innovations that make Cirrus an industry leader:

Better information =  "informed"  decisions

As always when you forget,  a careful reminder will get things back to normal

Overnight - The world of aviation fuel level measurement changed

Iphone App showing fuel level 

Just like the classic instrument six pack.

Seemingly while you weren't looking  -   The days of simple capacitive and resistive fuel senders disappeared and were relegated to history. 


 You need only to look at the parts manuals for the latest Cirrus SR20, SR22 or Cessna 172, 182 & 206 single engine aircraft.     Take a real close look and  you will see terms like AMR and TDR  (Anisotropic Magneto Resistive & Time Domain Reflectometry).  And instead of a voltage or resistance output to be checked in the maintenance manual - you will see terms like CANBUS and Frequency.  

So what changed ...... well quite a lot ...... the digital age hit fuel level.

  • The FAA requires there to be working fuel gauges in aircraft.                                                        Fuel gauges that are accurate throughout the range.                                                       Yes the FAA really wants accurate gauges in the aircraft
    • The FAA is making that very clear -
      • The pilot is required to assure by Part 91.205 they have working fuel gauges
        • Working - providing accurate fuel level through the full tank range
      • The aircraft manufacturer is required  by Parts 23.963, 23.1305, 23.1337, 23.1555 to have working fuel gauges
        • These very clearly indicate  fuel gauges give fuel level through the whole tank range.
        • Note:  Some of these requirements were recently revised.
  • The rate of fuel starvation events remained unchanged.
    •  2 to 3 per week in the US 

For a long time,  excuses were made for fuel level reporting systems in General Aviation aircraft.   

General aviation fuel gauges were (insert your own adjective) bad , pilots didn't trust them and did not rely on the information they provided.   Uncharacteristically,  the FAA turned a blind eye to the regulations, tacitly acknowledging the state of the art in their own documents and publications.   

Pilots sought and effectively utilized "work arounds" - aircraft manufacturers and avionic shops installed or incorporated equipment in the aircraft.  This was not required equipment, but gave pilots confidence in their fuel level while in flight and a cross check of their  fuel calculations for their aircraft at any time.   The almost ubiquitous fuel totalizer or range graph is on virtually every piece of modern avionic equipment.

Fuel leaking from an aircraft fuel pump
The posting on the web (pictured above) of these kind of pilot work arounds reflect the complacency,  in that The pilot  with his "trusted" iPhone App stands in stark contrast to the aircraft fuel gauge.

So why did the FAA really want working fuel gauges in the aircraft.  You would believe that somewhere in the digital age and the onslaught of new avionic features the simple fuel gauge would be relegated to the trash heap.   

Well... nothing but a working fuel gauge .... can tell you exactly what you actually have onboard the aircraft
