Yes, the installation of CiES FAA TSO fuel quantity systems into most type certificated GA aircraft is approved under a FAA AML STC and an EASA STC. Based on the success of our proven TSOA process and our commercial success in OEM programs, the FAA authorized STC installation of the CiES digital fuel senders as a replacement for existing resistance or capacitance-based fuel quantity in GA aircraft. These senders interface with modern cockpit instrumentation. We are working on adding other aircraft and instrumentation to the STC.
