(a)  
Flight control parameters for body yaw rate, lateral acceleration, bank angle, leading edge flaps, spoiler position, control wheel position, aileron position, trailing edge flap position, rudder position, column position and elevator position are presented for display.

 (b)  
Digital readouts, directional pointers and textual symbology are white in color. Captions are colored cyan.

 (c)  
Body yaw rate, lateral acceleration and bank angle data is received by the EIU on an ARINC 429 data bus from the L,C, or R Inertial Reference Unit (IRU).

 (d)  
Leading edge flap, trailing edge flap, flap actuator, flap drive, flap handle and horizontal stabilizer positions are received by the EIU on an ARINC 429 data bus from the Flap Control Unit (FCU).

 (e)  
Spoiler, control wheel, aileron, rudder, rudder pedal, steering column, and elevator position data is received by the EIU on an ARINC 429 data bus from the Surface Position Digitizer (SPD).

 (2)  
Body Yaw Rate

 (a)  Displayed in units of degrees per second. The directional symbol will point to the right for airplane nose right and to the left for airplane nose left.
