Which parameters are exempt from recording on a flight data recorder for aeroplanes with an MCTOM of 27,000 kg or below, and under what conditions?

For aeroplanes with an MCTOM of 27,000 kg or below, the FDR does not need to record parameters 14 (outside air temperature or total air temperature) and 15b (autopilot operating modes, autothrottle and AFCS systems engagement status and operating modes) of Table 1 if any of the following conditions are met: (1) the sensor is not readily available; (2) sufficient capacity is not available in the flight recorder system; or (3) a change is required in the equipment that generates the data.

For aeroplanes with an MCTOM exceeding 27,000 kg, which parameters may be omitted from the FDR if the signals are not available in digital form?

For aeroplanes with an MCTOM exceeding 27,000 kg, the FDR does not need to record parameter 15b of Table 1 and parameters 23, 24, 25, 26, 27, 28, 29, 30 and 31 of Table 2 if, among other conditions, for navigational data (NAV frequency selection, DME distance, latitude, longitude, ground speed and drift), the signals are not available in digital form.

What is the applicability date for the parameters listed in AMC4 CAT.IDE.A.190?

The parameters apply to aeroplanes first issued with an individual Certificate of Airworthiness (CofA) on or after 1 June 1990 up to and including 31 March 1998.

Which parameters are required for all aeroplanes with an MCTOM exceeding 5,700 kg, and which are only required for those exceeding 27,000 kg?

For all aeroplanes with an MCTOM exceeding 5,700 kg, Table 1 lists parameters 1 through 15b (e.g., time, pressure altitude, airspeed, heading, normal acceleration, pitch/roll attitude, engine power, flap positions, thrust reverse, spoilers, temperature, autopilot status). For aeroplanes with an MCTOM exceeding 27,000 kg, Table 2 adds parameters 16 through 32 (e.g., longitudinal/lateral acceleration, control surface positions, radio altitude, glide path/localiser deviation, NAV/DME, landing gear, GPWS, angle of attack, hydraulics, navigation data).

What is the purpose of recording manual radio transmission keying, and what alternative is allowed?

Manual radio transmission keying is a required parameter (No. 8 in Table 1) unless an alternate means to synchronise FDR and CVR recordings is provided.

Which parameters are listed in Table 2 for aeroplanes with an MCTOM exceeding 27,000 kg?

Table 2 lists the following additional parameters: 16 longitudinal acceleration, 17 lateral acceleration, 18 primary flight controls – control surface position and/or pilot input (pitch, roll and yaw), 19 pitch trim position, 20 radio altitude, 21 glide path deviation, 22 localiser deviation, 23 marker beacon passage, 24 master warning, 25 NAV 1 and NAV 2 frequency selection, 26 DME 1 and DME 2 distance, 27 landing gear squat switch status, 28 ground proximity warning system (GPWS), 29 angle of attack, 30 hydraulics each system (low pressure), 31 navigation data, and 32 landing gear or gear selector position.

What is the scope of AMC4 CAT.IDE.A.190 in terms of aeroplane categories?

AMC4 CAT.IDE.A.190 applies to aeroplanes with an MCTOM of more than 5,700 kg, with additional parameters for those exceeding 27,000 kg, and is limited to aeroplanes first issued with an individual CofA on or after 1 June 1990 up to and including 31 March 1998.

ED Decision 2019/019/R

LIST OF PARAMETERS TO BE RECORDED FOR AEROPLANES FIRST ISSUED WITH AN INDIVIDUAL CofA ON OR AFTER 1 JUNE 1990 UP TO AND INCLUDING 31 MARCH 1998

(a) The FDR should, with reference to a timescale, record:

(1) the parameters listed in Table 1 below; and

(2) the additional parameters listed in Table 2 below for those aeroplanes with an MCTOM exceeding 27 000 kg.

(b) The FDR of aeroplanes having an MCTOM of 27 000 kg or below does not need to record parameters 14 and 15b of Table 1 below if any of the following conditions are met:

(1) the sensor is not readily available;

(2) sufficient capacity is not available in the flight recorder system; or

(3) a change is required in the equipment that generates the data.

(c) The FDR of aeroplanes having an MCTOM exceeding 27 000 kg does not need to record parameter 15b of Table 1 below, and parameters 23, 24, 25, 26, 27, 28, 29, 30 and 31 of Table 2 below, if any of the following conditions are met:

(1) the sensor is not readily available;

(2) sufficient capacity is not available in the FDR system;

(3) a change is required in the equipment that generates the data; or

(4) for navigational data (NAV frequency selection, DME distance, latitude, longitude, ground speed and drift), the signals are not available in digital form.

(d) The FDR does not need to record individual parameters that can be derived by calculation from the other recorded parameters.

(e) 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.
