INSTRUMENT APPROACH PLATES
Each instrument approach plate consists of four sections: planview, profile view, landing
minimum section (and notes), and airport sketch. Refer to Figures 2 and 3, the VOR RWY 19
approach at NAS Pensacola and the VOR-A or TACAN at Dothan.
1. Margin Identification - The approach name is derived from the type facility providing
final approach course guidance. The runway number is included when the final approach course
is within 30° of runway centerline (ex: VOR RWY 19) or a sequential letter code is included
when the final approach course is more than 30° from the runway centerline (ex: VOR-A or
a. VOR/DME in the margin means that both VOR and DME receivers and ground
equipment are required to execute the approach. The procedure is not authorized when either
VOR or DME is inoperative. TACAN azimuth is to authorized for course guidance.
b. VOR/DME or TACAN in the margin means the procedure may be executed using
VOR or TACAN azimuth for course guidance and DME is required.
c. VOR OR TACAN in the margin means a VOR instrument approach using a
VORTAC facility has been approved for use by TACAN equipped aircraft. In Figure 3 the
procedure turn could be executed using either VOR or TACAN azimuth to position the aircraft
on final approach or if DME equipped, an arcing maneuver could be used with VOR or TACAN
azimuth on final approach.
2. Planview - This is a bird's eye view of the approach procedure, including procedure turn
or another specified initial approach segment, minimum safe altitudes, courses for the final
approach segment, obstructions, and navigation and communication frequencies. Data shown
within the distance circle (normally 10 NM) is always shown to scale. Dashed circles are used to
indicate needed information for the procedure which will not fit to scale within the plan view and
include Enroute Facilities (low altitude airways navaids, fixes, and intersections shown in their
relative position around the approach facility) and Feeder Facilities (navaids, fixes, and
intersections used by ATC to direct aircraft to intervening fixes between the enroute structure
and the initial approach fix, Figure 3).
"ASR" or "PAR" listed below the communications information indicates that radar
approaches and radar vectors to final approach course are available. The term "Radar Vectoring"
means that vectors to final approach course are available, but radar approaches are not.
3. Profile View - shows a side view of approach procedures (Figure 4). The profile
a. Initial approach fix altitude (not specified for all approaches).
b. Procedure turn altitude.
c. Final Approach Fix altitude.
