AMC2 CAT.IDE.H.190 Flight data recorder

AMC2 CAT.IDE.H.190 defines FDR parameter lists for helicopters by MCTOM and CofA date, including tables for ≤7,000 kg, >7,000 kg, and electronic display systems, with conditions for omissions.

Frequently Asked Questions

Helicopters having an MCTOM of more than 3 175 kg and first issued with an individual CofA on or after 1 August 1999 and before 1 January 2016, and helicopters having an MCTOM of more than 7 000 kg or an MOPSC of more than 9 and first issued with an individual CofA on or after 1 January 1989 and before 1 August 1999.

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

The section does not state an applicability date on or after 2026-03-27; it only defines groups by CofA issue dates (e.g., on or after 1 August 1999 and before 1 January 2016).

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

The FDR must record the parameters listed in Table 1 of AMC2 CAT.IDE.H.190, which include time, pressure altitude, airspeed, heading, normal acceleration, pitch and roll attitude, manual radio transmission keying, engine power, main rotor speed, rotor brake, primary flight controls, outside air temperature, autopilot and stability augmentation engagement, and warnings.

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

Table 2 of AMC2 CAT.IDE.H.190 applies to helicopters with an MCTOM of more than 7 000 kg.

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

The additional parameters listed in Table 3 of AMC2 CAT.IDE.H.190 must be recorded, including selected barometric setting, selected altitude, speed, Mach, vertical speed, heading, flight path, decision height, EFIS display format, and multi-function/engine/alerts display format.

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

Parameter 19 (indicated sling load force) does not need to be recorded if the sensor is not readily available or if a change is required in the equipment that generates the data.

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

Individual parameters that can be derived by calculation from the other recorded parameters need not be recorded, if agreed by the competent authority.

* Aviation.Bot's Suggestion - Always consult the original regulation for confirmation

The parameters should meet, as far as practicable, the performance specifications (range, sampling intervals, accuracy limits and resolution in read-out) defined in AMC3 CAT.IDE.H.190.

ED Decision 2019/019/R

LIST OF PARAMETERS TO BE RECORDED FOR HELICOPTERS HAVING AN MCTOM OF MORE THAN 3 175 KG AND FIRST ISSUED WITH AN INDIVIDUAL COFA ON OR AFTER 1 AUGUST 1999 AND BEFORE 1 JANUARY 2016 AND HELICOPTERS HAVING AN MCTOM OF MORE THAN 7 000 KG OR AN MOPSC OF MORE THAN 9 AND FIRST ISSUED WITH AN INDIVIDUAL COFA ON OR AFTER 1 JANUARY 1989 AND BEFORE 1 AUGUST 1999

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

(1) for helicopters with an MCTOM between 3 175 kg and 7 000 kg the parameters listed in Table 1 below;

(2) for helicopters with an MCTOM of more than 7 000 kg the parameters listed in Table 2 below;

(3) for helicopters equipped with electronic display systems, the additional parameters listed in Table 3 below; and

(4) any dedicated parameters relating to novel or unique design or operational characteristics of the helicopter.

(b) The FDR of helicopters with an MCTOM of more than 7 000 kg does not need to record parameter 19 of Table 2 below, if any of the following conditions are met:

(1) the sensor is not readily available; or

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

(c) Individual parameters that can be derived by calculation from the other recorded parameters need not to be recorded, if agreed by the competent authority.

(d) The parameters should meet, as far as practicable, the performance specifications (range, sampling intervals, accuracy limits and resolution in read-out) defined in AMC3 CAT.IDE.H.190.

(e) If recording capacity is available, as many of the additional parameters as possible specified in table II-A.2 of EUROCAE Document ED 112 dated March 2003 should be recorded.

(f) For the purpose of this AMC, a sensor is considered ‘readily available’ when it is already available or can be easily incorporated.
