The FDR must record: active AFCS mode, radio altitude or terrain elevation, current navigation source, vertical and lateral deviation with respect to the current active navigation path, DME 1 & 2 distances, drift angle, wind speed, and wind direction.

What parameters related to ice must be recorded?

Ice detection and the status of de-icing or anti-icing system must be recorded.

What parameters related to alerts must be recorded?

Alerts (including master warning and master caution status) must be recorded, and if applicable, traffic advisory or alerts, and obstacle and terrain alerts.

What parameters related to aircraft state must be recorded?

The FDR must record: time, altitude, latitude, longitude, indicated airspeed or calibrated airspeed, ground speed, outside air temperature (OAT), heading (magnetic or true), track, vertical speed, pitch attitude, roll attitude, longitudinal acceleration (body axis), normal acceleration, lateral acceleration, roll rate or roll acceleration, pitch rate or pitch acceleration, and yaw rate or yaw acceleration.

What parameters related to aircraft configuration must be recorded?

The FDR must record: wings angle (if applicable), nacelles angle (if applicable), air-ground status such as weight on wheels or equivalent parameter, and landing gear position (if the data source is used by VCA systems or available to the pilot).

What parameter related to voice communications must be recorded?

Manual voice transmission keying (if voice communications are used) must be recorded.

Which parameters must be recorded for electric engines on a VCA?

For electric engines, the FDR must record: rotation speed of each rotor or propeller (in rpm), health status of each electric engine controller, temperature of each electric engine, temperature of each electric engine controller, measured electrical current for each electric engine, and for liquid-cooled electric engines, pressure and temperature of the cooling liquid.

What flight control parameters are required for FDR recording?

The FDR must record pilot input positions on all axes and corresponding flight control outputs (e.g., target rpm for each electric engine, flight surface positions, etc.), and the status of each flight control computer.

Which battery parameters must be recorded by the FDR?

For each battery used for propulsion and/or flight controls, the FDR must record: health status, state of charge (SOC), voltage, temperature, current flow, state of power (SOP) if available, and calculated remaining flight time if available.
