Description
This AC provides aircraft owners, operators (i.e., certificate holders), and the flying public with information and guidance to comply with Title 14 of the Code of Federal Regulations (14 CFR) part 91, §91.21. Section 91.21 was established because of the potential for portable electronicdevices (PED) to interfere with aircraft navigation or communication systems, and prohibits the operation of PEDs not installed aboard U.S.-registered civil aircraft while operating under instrument flight rules (IFR). Section 91.21 permits the use of specified PEDs and other devices the operator of the aircraft has determined will not interfere with the safe operation of the aircraft. The recommendations contained herein are one means, but not the only means, of complying with § 91.21 requirements pertaining to the operation of PEDs.
