By means of the HDG V/S - TRK FPA pushbutton switch on the FCU, the crew can choose either set of basic modes for the AFS, and subsequent presentation on the PFD:
- with the HDG V/S mode, the A/C attitude presentation is privileged,

- with the TRK FPA mode, the A/C symbol is dimmed and the flight path vector symbol appears giving the A/C actual flight path angle and drift angle (track).

The flight path vector symbol provides the pilot with the A/C present flight path angle and the A/C present track information.
This symbol provides the pilot with the display of his actual flight path trajectory, in longitudinal and in vertical so that he sees no discontinuity when "switching" from this symbol on the PFD to the view of the outside world through the windshield.
The Flight Path Vector lateral displacements are limited to 21 degrees drift angle.

飞行航迹向量电门
飞行航迹向量（FPV）电门可在姿态显示器上显示FPV符号。
