Flight data recorder
LIST OF PARAMETERS TO BE RECORDED FOR AEROPLANES FIRST ISSUED WITH AN
INDIVIDUAL CofA BEFORE 1 JUNE 1990
(a) The FDR should, with reference to a timescale, record:
(1) the parameters listed in Table 1 below;
(2) the additional parameters 6 to 15b of Table 2 below, for aeroplanes with an MCTOM
exceeding 5 700 kg but not exceeding 27 000 kg and first issued with an individual
CofA on or after 1 January 1989, when the following conditions are met:
(i) sufficient capacity is available on a flight recorder system;
(ii) the sensor is readily available; and
(iii) a change is not required in the equipment that generates the data;
(3) the additional parameters from 6 to 15b of Table 2 below, for aeroplanes with a
maximum certificated take-off mass exceeding 27 000 kg that are of a type first type
certified after 30 September 1969; and
(4) the additional parameters listed in Table 2 below for aeroplanes with an MCTOM
exceeding 27 000 kg and first issued with an individual CofA on or after 1 January
1987, when the following conditions are met:
(i) sufficient capacity is available on a flight recorder system;
(ii) the sensor is readily available; and
(iii) a change is not required in the equipment that generates the data.
(b) The FDR of aeroplanes with an MCTOM exceeding 27 000 kg that are of a type first type
certified after 30 September 1969 does not need to record the parameters 13, 14 and 15b
in Table 2 below, when any of the following conditions are met:
(1) sufficient capacity is not available on a flight recorder system;
(2) the sensor is not readily available; and
(3) a change is required in the equipment that generates the data.
(c) The parameters to be recorded should meet, as far as practicable, the performance
specifications (range, sampling intervals, accuracy limits, and resolution in read-out)
defined in Table 1 of AMC5 CAT.IDE.A.190).
(d) When so determined by the CAA, the FDR does not need to record individual parameters
that can be derived by calculation from the other recorded parameters.
