TestVonics Flight Line Cart (FLC) was specifically designed to protect the TTU-205 against damage. Many TTU-205 units are damaged through daily mishandling due to the test sets weight and various handling procedures. In addition, it provides for easy transportation of the TTU-205 from the tool crib or shop to the aircraft under test. With new RVSM requirements for testers, the FLC provides all the protection necessary to ensure that RVSM specifications within the tester are kept.
