Class 1 EFBs are Portable Electronic Devices (PED), are stowed, not normally used during take-off and landing operations, and do not require an administrative process to remove them from the aircraft.

Class 2 EFBs are normally mounted in a position where they are utilized during all phases of flight and require an administrative process to remove/replace from the aircraft. Both Class 1 and 2 EFBs are considered Portable Electronic Devices. Fixed equipment such as computer mounts or docking stations require design approval.

 Class 3 EFBs are fixed, installed equipment and therefore require installation design approval.

	Type A Applications - Use pre-composed and fixed data - May be hosted on any of the hardware classes - Require operational approval Examples include: Flight Operations Manuals (FOM), Company Standard Operating Procedures (SOP), fault reporting applications, etc.
	Type B Applications - Use dynamic and interactive data - May be hosted on any of the hardware classes - Require operational approval - Require regulatory agency evaluation Examples include: performance calculations (such as takeoff, en route, and landing), weight and balance calculations, weather and aeronautical data, etc.
