The FAA this week approved the uAvionix AV-20-S multi-function display as an advanced time-keeping device equivalent and hence a replacement for the sweep-second-hand clocks of old. The unit is considered a replacement for clocks in Part 23, Class I and II IFR aircraft per advisory circular AC 20-94A. The new AV-20-S meets the requirements of Part 91.205 (d)(6). The Non-Required Safety Enhancing Equipment (NORSEE) certification has also been updated to reflect the approval.
