CiES is a new technology for measuring fuel quantity in aircraft. The CiES patented fuel sender technology is a digital, non-contact method designed exclusively for aircraft and the aircraft operating environment. CiES aims to replace senders originally sourced from the automotive or agricultural field that have been a mainstay in general aviation aircraft.
“For years, pilots of type certificated aircraft have suffered with marginal fuel quantity systems,” said CiES President Scott Philiben. “The systems in many aircraft are repurposed fuel senders and gauges for agricultural equipment. The current situation with these systems has gotten so bad that many pilots don’t trust or rely on their fuel quantity instrument. When you sit back and look at all the workarounds pilots now use to replace what should be quality fuel instrumentation, something really had to be done,” continued Philiben. “Pilots are relying on workarounds (such as calibrated sticks and warning timers) that are still resulting in three to four fuel-related accidents per week. The plain truth is that aircraft fuel quantity systems were really crying out for a new and better technology.”
Last year, in discussions with the FAA Small Aircraft Directorate, CiES illustrated how their technology could easily replace older failing fuel quantity indication. The FAA, interested in bringing newer technology to the market, was aware of CiES’s success in OEM applications and the fit, form, and function capability of their design and opened the door for an AML retrofit STC.
“I’m really encouraged that CiES has made the effort in getting an AML STC done,” said Melvin Johnson, FAA Small Aircraft Directorate Manager. “Helping the GA fleet have accurate and dependable fuel indication will definitely have an impact on safety.”
The CiES digital fuel quantity system utilizes an advanced technology sensor system that allows repeatable accurate measurement of fuel in aircraft tanks. This patented sensor system allows fuel measurements down to a change in fuel level less than 0.03 of an inch. This measurement represents much less than 10ths of a gallon of AVGAS or Jet A. The non-contact measurement method insures a lifetime of trouble-free operation providing stable, consistent fuel level output.
The initial STC allows the CiES to replace the existing fuel quantity senders in:
|Beech 33, 35, 36, 55, 58||Mooney|
|Cessna 150, 152, 170, 172, 175 177, 177RG, 180, 182, 185, 206, 207, 210||Vulcanair P68|
|Cirrus SR20 SR22 Fuel & TKS||Gippsland GA8|
|Piper PA22,PA23, PA24, PA28, PA30, PA31, PA32, PA39, PA44||Pilatus PC 6|
|American Champion||Fairchild 24|
More aircraft approvals are expected to follow shortly.
