MCTOM exceeding 27 000 kg;
(3) any dedicated parameters relating to novel or unique design or operational
characteristics of the aeroplane as determined by the CAA; and
(4) the additional parameters listed in Table 3 below, for those aeroplanes equipped with
electronic display systems.
(c) The FDR of aeroplanes first issued with an individual CofA before 20 August 2002 and

listed in Table 3 for which:
(1) the sensor is not available;
(2) the aeroplane system or equipment generating the data needs to be modified; or
(3) the signals are incompatible with the recording system;
(d) The FDR of aeroplanes first issued with an individual CofA on or after 1 April 1998 but not

specifications (ranges, sampling intervals, accuracy limits, and resolution in read-out)
defined in Table 1 of AMC3 CAT.IDE.A.190.
(f) For aeroplanes with novel or unique design or operational characteristics, the additional
