Portable electronic devices (PEDs)/Electronic flight bags (EFB) are an important flight deck enabling technology for achieving NextGen operational improvements and capabilities. One common EFB application is electronic charts, which can vary in presentation quality due to PED screen size and resolution. The size of the electronic chart may be further limited by the design and layout of the electronic charting software. The FAA specifies guidance for the display of electronic charts in the current version of Advisory Circular (AC) 120-76, Guidelines for the Certification, Airworthiness, and Operational Use of Electronic Flight Bags.
