This standard covers three (3) basic types of flight recorders as defined below:

TYPE I Cockpit Voice Recorder (only) - Records voice communication (among flight crew and radio communication to and from aircraft crew) and cockpit area sound.

TYPE II Flight Data Recorder (only) - Records aircraft flight data parameters.

TYPE III Cockpit Voice/Flight Data Recorder Combination - Records all TYPE I and TYPE II requirements in a composite unit.

All requirements specified in Sections 3, 4, 5, 6 and 7 of this standard shall be applicable to all recorder types unless otherwise noted.

Purpose:

This Aerospace Standard (AS) specifies minimum performance standards for recording automatically aircraft flight parameters and (or) aural communication between flight crew members, aural warning sounds, and communications to and from aircraft necessary for flight operations. It is the intent of this standard to allow for the use of individual Cockpit Voice Recorder (CVR) or Flight Data Recorder (FDR) equipment, or a combination CVR/FDR. These equipments have been identified as TYPE I, II and III, thereafter as identified by paragraph 1.1.
