APPROACH PROCEDURES
Ensure the approach has been entered into the FMS flight plan,
and that it is currently active in the IFD.
Using the transition dropdown menu in the FMS, an approach can
be selected and flown as a full published procedure starting at an
IAF or as
“Vectors” (i.e. vectors-to-final).
When an IAF is selected, unless the leg preceding the approach
ends at the IAF, the approach will be preceded by a discontinuity.
If it is appropriate and safe to proceed direct from the last leg
before the approach to the IAF, then just close the gap and the
flight plan will naturally sequence onto the approach without
further intervention. Otherwise, when appropriate, use either the
“Activate Leg” or “Activate Approach” LSKs or “Direct-To” to
activate a leg on the approach.
When Vectors is selected, the approach is preceded by a
discontinuity saying “Vectors To Final – Inactive”. That
discontinuity cannot be closed, so operator intervention is
required. When cleared for the approach, the typical action is to
activate the leg to the FAF using one of the following techniques:

Press the “Activate Approach” LSK

Move the cursor to the leg to the FAF and press the
“Activate Leg” LSK

Move the cursor to the discontinuity and press the
“Activate VTF” LSK
Once a leg in the approach is active
, “Inactive” will be removed
from the discontinuity.

Due to mathematical rounding, it is possible that
course being sent to an EFIS for digital display may
be 1 degree off from the published approach chart.
