315. PLAN VIEW
The availability of radar is indicated below the communications information section by the
appropriate letters "ASR," "PAR," "ASR/PAR." View the upper left-hand corner of the plan
These terms are applied as follows:
ASR: Airport Surveillance Radar approach procedures are available at the airport, and radar
vectoring is also available.
PAR: Precision Approach Radar approach procedures are available.
RADAR VECTORING: Radar Vectoring is available but radar approaches are not available.
VHF and UHF communication frequencies used by approach control, tower, and ground control
facilities will be listed. Also note the frequencies for ATIS (Automatic Terminal Information
Service) will be listed if available. The star in front of the ATIS frequency denotes less than
The plan view presents a bird's eye view of the entire procedure. Information pertaining to the
initial approach fixes, procedure turn, minimum safe altitudes, final approach course, and
navigation and communication frequencies are listed on the plan view.
Data shown within maneuvering circle is always shown to scale. The dashed circles are used
when all the information necessary to the approach will not fit to scale within the limits of the
The Feeder Facilities are shown, in their relative position, navigational aids, fixes, and
intersections used by air traffic controllers to direct aircraft to fixes between Victor airways and
the Initial Approach Fix (IAF). Minimum altitude and distance between fixes to the IAF are
shown with the magnetic course.
The Enroute Facilities ring shows, in their relative position, navigational aids, fixes and
intersections that are part of the Enroute Low Altitude Airway structure which are used in the
Minimum Safe Altitudes (MSA) are published for emergency use on approach procedure charts
utilizing VOR, TACAN, ILS, NDB or GPS type facilities. The altitude shown provides 1000
feet of clearance above the highest obstacle in the defined sector to a distance of 25 NM from the
facility. As many as four sectors may be depicted with different altitudes for each sector
displayed in rectangular boxes in the plan view of the chart. A single altitude for the entire area
may be shown in the lower right portion of the plan view. Navigational course guidance is not
assured at the MSA within the sectors. View ILS RWY 20 at Patrick AFB and notice the
different altitudes associated with the various MSA sectors. On RNAV (GPS) approaches the
