A330/A340 2.80.3 Flight Path Vector
FCTM REV 1 (6 JUN 05)
Non-Precision Approach
The FPV is particularly useful on non-precision approaches as the pilot can select values for the inbound track and final descent path angle on the FCU. Once established inbound, only minor corrections should be required to maintain an accurate approach path. Tracking and descent flight path can be monitored by reference to the track indicator and the bird. Be aware, however, that the bird only indicates a trajectory and not guidance to a ground based facility. For example, when selecting FPA to create a synthetic glide path, the aircraft will be correctly positioned only if it commences descent at the right point in space. Therefore, although the bird may indicate that the aircraft is on the correct trajectory, it does not necessarily mean that the aircraft is on the correct final approach path, since it may only be paralleling the intended path. When the aircraft is disturbed from the original trajectory, the pilot must adjust either its track or its flight path angle or both in order to obtain guidance back to the original trajectory.
Visual Circuits
The FPV is useful as a cross-reference when flying visual circuits. On the downwind leg, put the wings of the bird on the horizon to maintain level flight. The downwind track should be set on the FCU. Place the tail of the bird on the blue track index on the PFD to maintain the desired track downwind.
On the final inbound approach, the track index should be set to the runway final approach course. A standard 30 approach path is indicated by the top of the bird's tail being just below the horizon and the bottom of the bird being just above the 50 pitch down marker.

FPV CONSIDERATIONS Dynamic Manoeuvres
The pilot must take care when performing a go-around with the FPV selected, as on some aircraft the HDG-V/S FD is not automatically displayed upon the selection of TOGA. In this case, it is important to use pitch attitude as the primary reference for the go-around and avoid any temptation to select the target attitude using the bird. The pitch attitude targets for a go-around are 150 for all engines operating and 12.50 for one engine inop. If not automatically displayed, selection of HDG-V/S should be made without delay during the go-around. The FPV is not used for take-off.
Reliability
As the FPV is derived from IRS data, it is therefore affected by the errors of the ADIRS. This may be indicated by a slight track error, typically in the order of up to +/-20.
