What is the regulation regarding the use of portable electronic devices during IFR flights?

The regulation concerning the use of portable electronic devices during IFR flights is that they cannot be used. This is primarily due to safety considerations and the need to maintain operational control of the aircraft. The Federal Aviation Administration (FAA) places strict limitations on the use of electronic devices because they can interfere with the aircraft's navigation and communication systems, especially in critical phases of flight such as instrument flight rules (IFR).

While there are exceptions for certain devices, such as those specifically designed for aviation purposes that meet the necessary standards, the general rule is a total restriction on personal electronic devices in IFR conditions to minimize potential distractions and ensure pilot focus is on flying and managing the aircraft. This is crucial for maintaining situational awareness and adherence to regulations designed to promote safety in aviation operations.
