VDEV
Vertical Deviation symbol
The vertical deviation from the
theoretical vertical profile
computed by the FMGC is
displayed in the following
conditions:
−
NAV mode engaged or HDG
mode with XTK lower than
4NM, and
−
FMGC in DESCENT or
APPROACH phase.
VDEV is shown:
−
On MCDU PROG page in
field [2R],
If conditions not met for
display the field is blank.
−
On PFD by a magenta
circle.
The range is ± 500 ft.
If VDEV greater than ±500
ft, symbol stays at upper or
lower range limit; PROG
page displays exact value.
If conditions not met for
display the symbol is not
shown.
ILS approach
When established on GS, VDEV
remains available on PROG
page, magenta circle is no
longer displayed on PFD.
