UAM.IDE.MVCA.191 Flight recorder

FLIGHT RECORDER OPERATIONAL PERFORMANCE REQUIREMENTS

(a)The flight recorder should record the parameters established in point (b) or point (c) and any other parameters that have been established during the type certification of the VCA.

(b)If the flight recorder records flight data, it should record at least the following parameters:

(1)relative time count;

(2)pitch attitude or pitch rate;

(3)roll attitude or roll rate;

(4)heading (magnetic or true) or yaw rate;

(5)latitude;

(6)longitude;

(7)positioning system: estimated error (if available);

(8)pressure altitude or altitude from a positioning system;

(9)time;

(10)ground speed;

(11)positioning system: track (if available);

(12)normal acceleration;

(13)longitudinal acceleration;

(14)lateral acceleration;

(15)remaining usable amount of fuel/energy; and

(16)amount of fuel/energy necessary to complete the remaining part of the flight, unless the alternative procedure described in AMC1 UAM.OP.VCA.191 is used.

(c)If the flight recorder records images, it should capture views of the main instrument displays at the pilot station(s). The recorded image quality should allow reading the following indications during most of the flight, as applicable:

(1)magnetic or true heading;

(2)time (if presented on the front instrument panel);

(3)pressure altitude;

(4)indicated airspeed;

(5)vertical speed;

(6)slip;

(7)OAT;

(8)attitude (if displayed);

(9)stabilised heading (if displayed);

(10)lift and thrust unit status;

(11)remaining usable amount of fuel/energy; and

(12)amount of fuel/energy necessary to complete the remaining part of the flight, unless the alternative procedure described in AMC1 UAM.OP.VCA.191 is used.

(d)If the flight recorder records a combination of images and flight data, each flight parameter listed in point (b) should be recorded as flight data or by means of images.

(e)The parameters to be recorded as flight data should meet the performance specifications (range, sampling intervals, accuracy limits and resolution in read-out) as defined in the relevant tables of EUROCAE Document 112B ‘Minimum Operational Performance Specification for Crash Protected Airborne Recorder Systems’ or any later equivalent standard accepted by EASA, or EUROCAE Document ED-155 ‘Minimum Operational Performance Specification for Lightweight Flight Recording Systems’, dated July 2009, or any later equivalent standard accepted by EASA.

(f)The operational performance requirements for flight recorders should be those laid down in:

(1)EUROCAE Document ED-155 or any later equivalent standard accepted by EASA for lightweight flight recorders; or

(2)in EUROCAE Document 112B or any later equivalent standard accepted by EASA for crash-protected flight recorders.
