Description / Abstract:
Basic Types of Flight Recorders:
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.
