New Advisory Circulars

Three Advisory Circulars newly issued by the FAA in December 2016 and January 2017 may provide much-needed guidance to operators seeking answers to a wide range of certification and operational questions. Two of the ACs revise existing guidance on Use of Flight Deck Displays of Digital Weather and Aeronautical Information (AC 00-63A) and Airworthiness Approval of Enhanced Vision System, Synthetic Vision System, Combined Vision System, and Enhanced Flight Vision System Equipment (AC 20-167A).

The FAA issued three new or revised Advisory Circulars (ACs) in late 2016 and early 2017 to provide guidance on certification and operational matters.
AC 00-63A revises guidance for flight deck displays of digital weather and aeronautical information (EFBs), while AC 20-167A updates procedures for the airworthiness approval of enhanced and synthetic vision systems.
A new AC, 20-188, offers guidance for determining the compatibility of proposed changes to an aircraft's type design with previously approved modifications, assisting installers and maintainers.

Three Advisory Circulars newly issued by the FAA in December 2016 and January 2017 may provide much-needed guidance to operators seeking answers to a wide range of certification and operational questions. Two of the ACs revise existing guidance on “Use of Flight Deck Displays of Digital Weather and Aeronautical Information” (AC 00-63A) and “Airworthiness Approval of Enhanced Vision System, Synthetic Vision System, Combined Vision System, and Enhanced Flight Vision System Equipment” (AC 20-167A). The third AC, meanwhile, AC 20-188, is new and concerned with “Compatibility of Changes to Type Design Installed on Aircraft.”

Revised EFB Guidance

The FAA has long maintained published guidance regarding display and use of flight information in the cockpit, whether restricted to installed avionics equipment or available on portable devices. The guidance typically targets commercial operations under FAR Parts 121 and 135, but also affects Part 91 operation of large and fractionally owned aircraft.
