On non-precision approaches, the final segment begins at the Final Approach Fix (FAF), which is identified with the Maltese cross symbol. When no FAF is depicted, the final approach point is the point at which the aircraft is established inbound on the final approach course. Stepdown fixes may also be provided between the FAF and the airport for authorizing a lower minimum descent altitude (MDA) and are depicted with the fix or facility name and a dashed line. Altitude restrictions at stepdown fixes on the final approach on procedures with both precision and non-precision minima are not applicable to precision (ILS, LPV, or LNAV/VNAV) use of the approach. On non-precision only approach procedures, the approach track descends to the MDA or VDP point, thence horizontally to the missed approach point. The missed approach track on non-precision approaches is symbolized using the hatched line pattern and begins at the missed approach point.

Visual Decent Point (VDP)
The Visual Descent Point (VDP), is shown by a bold letter “V” positioned above the procedure track and centered on the accompanying dashed line. (See example below.) The VDP is a defined point on the final approach course of a non-precision straight-in approach procedure from which normal descent from the MDA to the runway touchdown point may be commenced.

Precision Approaches On precision approaches, the glideslope (GS) intercept altitude is illustrated by a lightning bolt symbol and an altitude. This is the minimum altitude for GS interception after completion of the procedure turn. Precision approach profiles also depict the GS angle of descent, threshold crossing height (TCH) and GS altitude at the outer marker (OM) or designated fix. The missed approach track is symbolized using the hatched line pattern. Where separate missed approach points exist for precision and non-precision approaches on the same chart, e.g., ILS and LOC, the track will be shown from the precision point only.

Vertical Descent Angle (VDA) and Threshold Crossing Heights (TCH)
A VDA and TCH may be published on non-precision approaches. For Copter approach procedures, a Heliport Crossing Height (HCH) will be depicted in place of the TCH. The VDA is strictly advisory and provides a means to establish a stabilized descent to the MDA. The presence of a VDA does not guarantee obstacle protection in the visual segment. If there are obstacles in the visual segment that could cause an aircraft to destabilize the approach between MDA and touchdown, the profile will not show a VDA and will instead show a note that states “Visual Segment-Obstacles”.

Visual Flight Path
Instrument approach procedures, including Copter approach procedures, that terminate or have missed approaches prior to the airport, and are authorized to proceed visual, shall depict the visual segment by the dashed line symbol from the missed approach point to the airport. The note “Fly visual” (“Proceed visually” on Copter procedures) along with the bearing and distance shall be shown leadered to the visual flight path.
RNAV charts sometimes have visual flight for LNAV/VNAV minima that do not start at the missed approach point. An additional note indicating “LNAV/VNAV” will be placed above the note.
Copter approach procedures with a VFR segment from the missed approach point will not depict the VFR segment with a line in the profile. The note similar to “Proceed VFR from MAP” will be shown.
