__________________
The PFD image is divided in 9 zones

**ON A/C ALL
The PFD image presents the main information necessary for the control of the A/C, arranged in the basic T configuration.
A grey background is permanently present on the screen.
**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299, 301-302,
If the SDAC detects AVIONICS VENT EXTRACT FAULT and AVIONICS VENT BLOWER FAULT conditions it sends a discrete signal to the DMCs which command the PFDs to suppress the grey background. This limits tube consumption and thus prevents them overheating. Tube operation is certified for 30 minutes without ventilation.

**ON A/C ALL
The aircraft attitude (pitch and roll) is indicated in the center part of the image by a cut-sphere shaped window which features a conventional ADI.
(1) Aircraft symbol R **ON A/C 106-149, 303-399, 401-499,
(Ref. Fig. 005)
**ON A/C ALL
The fixed symbol is in yellow color, it comprises 3 parts: two simplified wing/landing gear parts plus a center part.
**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299, 301-302,
It provides the pilot with a quick glance attitude information, both in pitch and roll with respect to the attitude sphere. When the pilot selects the TRK FPA mode on the FCU instead of the HDG V/S mode, the A/C symbol is dimmed (except at take off).

(Ref. Fig. 006)
**ON A/C ALL
The A/C present pitch angle is given by the vertical displacements of the pitch attitude scale with respect to the center of the A/C symbol. The scale moves behind the cut-sphere shaped window, limited by the lines of an upper and a lower sector. The scale rotates around the center of the A/C symbol in accordance with the A/C present roll angle.
**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299, 301-302,
The pitch scale comprises white reference lines and associated pitch angle values. The lines are given every 2.5 degrees from 0 to 10 degrees, then for the 15 degrees, 20 degrees, 30 degrees, 50 degrees and 80 degrees values. Beyond 30 degrees, red large arrow heads (V-shaped) indicate an excessive attitude and the direction to follow in order to reduce it. (Ref. Fig. 007)
