ED Decision 2025/020/R
SCOPE OF THE FLIGHT DATA MONITORING (FDM) PROGRAMME
(a) A set of core FDM events or FDM measurements should be selected to cover, as far as possible, the most significant risks identified by the operator. The definitions of FDM events and FDM measurements in this core set should be designed to help identify deviations from the standard operating procedures that are beyond what is considered normal practice and not only occurrences that require reporting to the competent authority or unscheduled continued airworthiness activity. The definitions of FDM events and FDM measurements in this core set should be continuously reviewed to reflect the operator’s current operating procedures and any newly identified safety risks.
(b) For all aeroplanes that are within the scope of point ORO.AOC.130 and first issued with an individual certificate of airworthiness (CofA) on or after 1Â January 2016, the FDM programme should monitor, to the extent possible with the available flight data and without requiring overly complex algorithms, precursors of the following key risk areas:
(1) risk of runway excursion during take-off or landing,
(2) risk of airborne collision,
(3) risk of aircraft upset, and
(4) risk of collision with terrain.
(c) If the necessary flight parameters are collected by the airborne systems used to obtain flight data, the FDM programme should monitor:
(1) exceedances indicating that the airworthiness of the aircraft may be affected and that are related to any of the following parameters:
(i) speed and configuration;
(ii) altitude;
(iii) accelerations;
(iv) attitude angles;
(v) engine limitations (e.g. those related to thrust parameters, exhaust gas temperature, vibration levels and reverse thrust versus aircraft speed);
(vi) aircraft weight; and
(2) caution and warning alerts to the flight crew, indicating that the airworthiness of the aircraft may be affected.
(d) Upon request by its competent authority, the operator should provide documentation identifying which types of occurrences are monitored with the FDM programme. This documentation should cover at least the occurrences subject to mandatory reporting and listed in Section 1 (excluding paragraph 1.5, point (3)) and Section 5 of Annex I to Commission Implementing Regulation (EU) 2015/1018. This documentation should include a short description of the applicable FDM event(s) or FDM measurement(s) for each type of occurrence monitored by the FDM programme.
[applicable from 1 January 2028 — ED Decision 2025/020/R]
AMC2 ORO.AOC.130 defines FDM programme scope: core events, monitoring of key risk areas for newer aeroplanes, parameter exceedances, and documentation for authorities.
