COOL FEATURE
FPL L4 LSK
Think of the L4 LSK on the IFD as your
“hook” into the FMS. The button changes
functionality based on the phase of flight or
instrument procedure you are on. This is described
in more detail in the FMS Hooks subsection of the
Navigation section of this manual.
TIPS AND TECHNIQUES
VTF Transitions
VTF transitions in the IFD provide guidance to the
extended centerline of the selected runway.
When assigned a VTF clearance on a SBAS
approach (WAAS- or EGNOS-based LPV, LP and
LNAV/VNAV) with an offset leg into the Final
Approach Fix (FAF) where the leg to the FAF is not
aligned with the final approach course (i.e. an
angled entry to the FAF), the pilot should ask the
ATC controller to clarify if those vectors are to
extended final or the published offset inbound leg to
the FAF.
In the case where ATC responds with the extended
final scenario, Avidyne recommends the pilot select
the “VTF” transition option in the FMS approach
dropdown list. In the case where ATC responds
with the published offset leg scenario, Avidyne
recommends the pilot activate the inbound leg to the
FAF from the FMS FPL tab to ensure the offset leg
is accounted for.
