Some instrument procedures include notes saying the following: “RNP 0.3
required” and are coded as an RNAV procedure. In these cases, select
manual RNP to see the RNP and ANP values on the PFD.
7.12.1. Approach Path Definition
Normal IAP path definitions are as specified in the procedure contained in
the navigation database. Deviations are provided with respect to the active
leg of the approach procedure.
7.12.2. VTF IFR Approach
In addition, the pilot may select a VTF IFR approach, indicating the pilot
does not intend to fly the entire procedure. When a VTF IFR approach is
selected, the EFIS creates an initial point (IP) waypoint on the extended
final approach course to provide deviations relative to the extended final
approach course. The IP is a fly-over defined exit heading waypoint, and
the leg prior to the IP is designated a discontinuity. Until the FAWP is
sequenced, the EFIS indicates a VTF IFR approach has been selected.
indicates guidance is not relative to a published
approach path, and TERPS clearances are not assured.
7.12.3. VTF VFR Approach
The pilot may select a VFR approach to a runway or user waypoint with a
defined approach bearing. When a VFR approach is selected, the EFIS
creates an IP waypoint approximately 12 NM on the extended final
approach course to provide deviations relative to the extended final
approach course. The IP is designated as a fly-over defined exit heading
waypoint, and the leg prior to the IP is designated as a discontinuity.
