Tractor Fuel senders need not apply, CiES Inc. announces that the best-selling TSO’d
digital and aircraft specific fuel quantity senders are now approved for STC installation in
most Cessna, Piper, Beech, Mooney & Maule aircraft.

CiES CC284022 Series & STC SE02511SE

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. We replace existing senders that were sourced from the automotive
or agricultural field that have been a mainstay in general aviation aircraft.

CiES is general aviation industry overwhelming choice for fuel quantity senders, over 1,750
aircraft in the field, already fly with CiES digital fuel quantity sensing systems. CiES fuel
quantity systems are included on all new Cirrus Aircraft SR20, SR22 and SR50 Jet, Quest
Kodiak, Vulcanair P68, Tecnam, Gippsland GA10, CAIGA with more to be added in the coming
months.

CC284022 Series Fuel quantity senders have amassed over 580,000 hours of operation in
OEM aircraft and have an outstanding record of near zero in service removals with over 12,000
senders fielded. CiES has the experience and capability to insure that GA aircraft fuel quantity
can and will be accurate in the aircraft of the future.

Scott Philiben, CiES President, said “For years, pilots of type certificated aircraft have suffered
with marginal fuel quantity systems. These 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 the their fuel quantity instrument. When
you sit back and look at all the work arounds pilots now use to replace what should be quality
fuel instrumentation something really had to be done. Pilots are relying on work arounds such
as calibrated sticks and warning timers that basically are still resulting in 3 to 4 fuel related
accidents per week. The plain truth is, 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 our
technology could easily replace older failing fuel quantity indication. The FAA, interested in
bringing newer technology was aware of our success in OEM applications and the fit form and
function capability of our design and opened the door for an AML retrofit STC.

“said Melvin Johnson, FAA Small Aircraft Directorate Manager “I’m really encouraged that CiES
has made the effort in getting an AML STC done. 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 tank. This patented sensor system
allows fuel measurements down to a change in fuel level to less than 0.03 of an inch. This
measurement represents much less than 10 ths 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:

Cessna 150, 152, 170, 172, 175 177, 177RG, 180, 182, 185, 206, 207 & 210
Piper PA 22, PA 23, PA 24, PA 28, PA 30, PA 31, PA 32, PA 39, PA 44
Beech 33, 35, 36, 55, 58
Cirrus SR20 SR22 – Both Fuel and FIKI Senders
Fairchild, Gippsland, Maule, Mooney, Vulcanair, American Champion, Pilatus,
Britten Norman

More aircraft approvals are expected to follow

Founded in 2010, CiES’s mission is to create the best aircraft systems for aviation and other
high value markets. With an enviable portfolio of OEM customers and platforms worldwide
CiES is the leading manufacturer of fuel quantity systems for GA Aircraft. Continuing a
tradition started with our introduction of their first digital fuel quantity system, CiES is
committed to developing innovative products at affordable prices for all aircraft manufacturers
& pilots.
