05 - TRAINEES’ ACTIONS
When selecting HDG/ VS - TRK/FPA push-button, note the changes on FCU, FMA modes
and ND/PFD displays.
FPD is commanding a trajectory. If followed it will give a required trajectory that is stabilized
by reference to the ground. FPV is an indicator of performance, and is not in itself a director
or a command.
However it is very useful in a non-precision approach. HDG/VS on the other hand is
referenced to the air mass.
The FPV shows the present lateral track and present flight path angle relative to you. It is
dynamic and indicates where we will be if all else remains the same. If any changes are
introduced, the FPV will show the result of these changes. There is a slight lag in response.
Great care must be taken to remember which mode is in operation, especially in
differentiating between VS (i.e. feet per minute) and FPA (an angle relative to the airplane).
This is determined by monitoring the FMA.
When flying a go-around, remember to use the aircraft attitude as the primary reference. It
should be noted that when using FPV, the aircraft attitude symbol is dimmed. The use of the
FPV is not recommended for high dynamic manoeuvres such as take-off and go-around.
The FPV, managed speed target on approach and the speed trend are efficient indications to
the crew of wind variation and windshear.
The accuracy of the FPV is directly linked to the accuracy of the IRS speeds. For example,
an error of 5 kt in ground speed may cause an error of up to 2.5° in track on the approach.
Therefore, during even short turnarounds, it is recommended to realign the IRS when ground
speed reaches 5 kt.
Wings level change of FD mode gives current TRK on current HDG.
Does not apply to a turn.

06 - COMPLETION STANDARDS
· Makes correct selection of FPV, with FPD as appropriate, and uses the information
provided to achieve the desired flight path.
