  1. @carusoam Well the ground filling component is a function of the smartphone APP I showed - tongue in cheek - for fuel level on the ground to replace a stick. With an accelerometer onboard the integral phone modem - aircraft attitude and ramp angle can be considered. This APP is being developed for several of our commercial customers where this is a critical issue. Equally hauling out a stick - does not inspire customer confidence. Kenmore - DeHavilland Beaver - Floats or Gear Cape Air - Tecnam P2012 - Commercial Application We are quite popular in Alaska for the reasons you stated in your post - weight performance is critical for several missions and commercial operators are utilizing the combined fuel information & GPS allow operators to put customers safely in places, that a lack of precise aircraft loading knowledge would have carried too much risk and liability. As the season is over we have this month, approx. 90 orders for Cessna 180, 185 headed in that direction. Our acceptance rate in Alaska is staggering. So the intention of this APP takes care of Tundra Tires, Floats or Conventional Gear without cluttering up the cockpit with unnecessary flight information. Once this portal is in place there are a lot of things that could be added in the future - tire pressure, oil level, De-ice fluid, oleo pressure, strain gauges for critical structure (not a Mooney Issue) - the list goes on ...... So yes - I think we are on to something.

    M20F Fuel Stick - I know I know

    Data I have - it isn't very interesting to most. But you are more than welcome to come on in and look through it. We will even provide coffee. All of it is tied to published data either ours filed with the FAA or that filed with the US government by some other organization. I have to do this, as we would reasonably expect that this would have to be proven to the FAA / NTSB or further in a court of law. This adds just a touch of voracity A stick you create for this use will never be mentioned or photographed in an incident or accident - don't believe me - the NTSB Accident files are open to anyone, Advisory Circular 23.17 the FAA specifically calls out that a totalizer can not be an approved fuel gauge Digital fuel flowmeters are not a required powerplant instrument except for turbine engine airplanes with an Amendment 23-43 certification basis. They are optional equipment and should not be considered replacements for fuel quantity or fuel pressure indicators What I am saying is - the methodology of getting a starting observed fuel value - Stick, observation, full tanks et all and then relying on a Totalizer or Time to determine in flight fuel level is not the intention of what should be used in a certified aircraft to determine actual in flight fuel level. Why - the FAA says so - or at least it says so in this location. An FAA stated design goal or recommendation is relavent regardless of how effective or accurate an alternative method is to a user in practice - this is the religious or rote component I mentioned. Because it is common or that everyone is doing it doesn't mean we should not reflect on it and ask why - or question the underlying reasons (Potentially that Fuel qty instrumentation in GA has been substandard or has not met or been maintained to the FAA design goal) The Standard for GA Fuel qty instrumentation is 3% of fuel tank value or 0.75 of a gallon on a 25 gallon tank - I know I am writing the ASTM spec and this relies on specifications for GA that have been written and published since the 1930's - so it has to be better than 1 gallon Bottom line - despite the advent and increasing usage of fuel totalizers the GA, fuel accident rate has remained unchanged. That fact is distressing, as this component is perceived as a safety item people rely on and tout the accuracy of. I hear your statement repeated countless times - my totalizer is accurate to less than a gallon. What I believe is that a totalizer or time in tanks has the potential to mislead or provide bad pilot information especially when it is critical information for continued flight. I believe, as do most of the people who have accurate fuel indication (Not vendor specific and a few Mooney owners) in that having the ability for a comparative in flight fuel quantity data from two different sources is a an item of safety - that I hope will be a proven better solution. i.e one that shifts the accident statistic southward, Doing something by rote for safety that has been proven by data to offer no change to the accident statistic is the classic definition of lack of careful thought or reflection.

    I simply post a picture of an app illustrating a different method with a comment of - "You still use a stick" There was no sales pitch or offer of any product just my logo, which is over on the left as well Can't we just get along.

    Cyril. I trust what we are doing in supplying accurate fuel level from a fixed location, is a very significant improvement on sticking a tank . Yes this is heresy to some, as this has been the time honored method that has kept some but not all safe. Aviation is like a religion - you trust what you were told at an early age and believe it throughout your life. It is a basic fact that what we can do relative to fuel level is better than you can do with a procedure with a stick. I will put up $1,000 for someone who believes they can be more accurate with a stick full stop. Name the place and location. We have 5,000 aircraft with our system, so I have users who back up my voracity. What is better is that our system travels with you when you fly, You can get a better than a stick reading in flight. - Level flight no turbulence. Initiating your flight with a basic stick level understanding of starting fuel level - has proven to be an issue.

    The app and aircraft interface are in final development, Mooney’s and Malibu’s have been shown it first. Some of you will be offered the app and the aircraft interface to beta test and provide feedback. There has to be benefits to being early adopters.

    Actually - I like the reaction. A fixed position (i.e. mounted in the tank) accurate reporting device should if designed correctly outperform A methodology that involves human interface, that coordinates a predictable repeatable action in a nearly impossible still volume of fuel with a porous and human marked stick. The ability to project that accuracy on the ubiquitous smartphone that everyone caries os just a succinct way of illustrating this disparity The last cars to come equipped with a stick are Early 1950's Volkwagon Beetles and MC TD's for a point of reference I am not driving in the illustration and I hardly qualify as a teenager. The fact that this former methodology (Stick) has no impact on fuel starvation and exhaustion statistic in aviation. An Actual Scientific Study was performed that indicated that this methodology for long distance flights is nearly universal or near 100% in the pilot population and slightly less so for a short distance flights. If you look at the current Nall Report - the Fuel Statistic remains stubborn while overall accidents in aviation are falling Funny - in speaking to people much older than me, it was equally unsuccessful in Volkswagen Beetles and MG TDs If I told you 10 years ago that you would take strangers into your house and rent them a spare room or get into a car with a total stranger to be taken somewhere - your arguments to those concepts may have had equal vitriol - yet here we are with Airbnb, Uber and Lyft The world does change

    Erratic idle... SOLVED!!

    Muuhh. Ha ha ha. Picture me setting down my morning coffee and wringing my hands in contemplation of my evilness. OK - evil test period over., now back to adding Cessna Twins to the AML
  11. Yes JPI has come around. Nobody in Aviation likes the new guy, that is a rule and probably in the CFRs I wasn’t so popular here as well. In later Mooneys there is a conversion box to take the analog resistive input and convert it. I don’t have one, but I suspect a voltage divider so that sensors from potential other manufacturers like Rochester could be used without changes to the instrument panel. Resistive to Frequency wasn’t a big item back then as fuel totalizers using frequency were new. This method was also applied to Bonanzas and Barons as another example. In most cases with a new Engine monitor or engine information system this box goes away. Garmin EIS would be the only potential exclusion as it accepts resistance, voltage and frequency, So the conversion box could stay, but the active question for the install shop is why.

    Need help with CGR-30P choices

    To be specific EI senders are variable voltage and Hall effect sensor based. CiES are Frequency or analog & frequency and are based on Anisotropic Magneto Resistive or AMR technology. Yes I dug into a EI sender to investigate potential patent infringement. a Google search on AMR vs Hall Effect will tell you more. Yes similar concept, but different in detail. CiES senders are TSO’d and that is a difficult accomplishment one you won’t see at this price point by any other manufacturer.

    CiES Fuel Senders Resource Thread

    Spending time in Willmar MN after OSH18. Thanks for stopping by . We are getting lots and lots of Mooney data and finishing up with a G1000 install. The Mooney G1000 fuel quantity interface which is similar to the Beech G36 and G58 leaves something to be desired, but it is working and calibrating. Pictures are not of the G1000 but of clean Mooney tanks. The charting and pdf are reference notes and a graph. The Senders individually supply data to the Garmin . And yes I know what the TCDS says for fuel qty owner wanted more....... The travel appears to be limited by a nutplate ot stop of which the Mooney has many. Mooney.pdf

    Nice - yes there is damping, but in this case it is mostly from the JPI side. We have several scenarios we can utilize depending on application. See u at OSH 18

    TKS quantity indicating 0.0?

    We have been supplying TKS senders to Cirrus since 2012 They do corrode more than the fuel senders, but not to a point where operation is degraded. No sender removals for TKS now at 5 yrs send us a bad one
