IRImplementing rule

UAM.IDE.MVCA.190Flight data recorder (FDR)

(a)A VCA with an MCTOM of more than 5 700 kg shall be equipped with a FDR that uses a digital method of recording and storing data, and for which a method of readily retrieving that data from the storage medium is available.

(b)The FDR shall record the parameters required to determine accurately the flight path, speed, attitude, engine(s) power, operation, configuration, and any parameter that has been established during the type certification of the VCA and shall be capable of retaining the data recorded during at least the preceding 25 hours.

(c)Data shall be obtained from the VCA sources that enable accurate correlation with information displayed to the pilot(s).

(d)The FDR shall automatically start to record the data not later than the VCA is capable of moving under its own power and shall stop automatically following lift and thrust units powering off at the end of the flight.

(e)If the FDR is not deployable, it shall have a device to assist in locating it under water with a minimum underwater transmission time of 90 days. If the FDR is deployable, it shall have an automatic ELT.

FDR OPERATIONAL PERFORMANCE REQUIREMENTS

(a)The operational performance requirements for FDRs should be those laid down in EUROCAE Document 112B dated August 2023, or any later equivalent standard accepted by EASA.

(b)The FDR should, with reference to a timescale, record the parameters established in Table 3 and Table 4, as applicable, and any parameters that have been established during the type certification of the VCA.
