Right traffic information is shown using the abbreviation 'RP' for right pattern, followed by the appropriate runway  number(s) (RP 18). Special conditions or restrictions to the right pattern are indicated by the use of an asterisk (*RP) to  direct the pilot to the Chart Supplement for special instructions and/or restrictions. The type “OBJECTIONABLE” associated with an airport symbol indicates that an objectionable airspace determination  has been made for the airport per FAA JO 7400.2 Section 4, Airport Charting and Publication of Airport Data. Objection- able airspace determinations are based upon a number of factors including conflicting traffic patterns with another airport,  hazardous runway conditions, or natural or man-made obstacles in close proximity to the landing area. FAA Regional  Airports Offices are responsible for airspace determinations. Address any challenges to objectionable airspace determina - tions to your FAA Regional Airports Office. AIRSPACE CONTROLLED AIRSPACE Controlled airspace consists of those areas where some or all aircraft may be subject to air traffic control, such as: Class  A, Class B, Class C, Class D, Class E Surface (SFC) and Class E Airspace. Class A Airspace  within the United States extends from 18,000' up to FL600. While visual charts do not depict Class A, it  is important to note its existence. Class B Airspace  is shown in abbreviated form on the Caribbean Charts (CAC) . The Sectional Aeronautical Chart (Sectional) and Terminal Area Chart (TAC) show Class B in greater detail. The MSL ceiling and floor alti - tudes of each sector are shown in solid blue figures with the last two zeros omitted. Floors extending "upward from above"  a certain altitude are preceded by a (+). Operations at and below these altitudes are outside of Class B Airspace. Radials  and arcs used to define Class B are prominently shown on TACs. Detailed rules and requirements associated with the  particular Class B are shown. The name by which the Class B is shown as   for example. Class C Airspace  is shown in abbreviated form on Caribbean Charts (CAC). Sectionals and TACs show Class C in greater detail. The MSL ceiling and floor altitudes of each sector are shown in solid magenta  figures with the last two zeros eliminated. FAA Chart Users’ Guide - VFR Terms and Symbols  The figure at left identifies a sector that extends from the surface to the base of the Class B. Class C Airspace is identified by name:  Separate notes, enclosed in magenta boxes, give the approach control frequencies to be used by arriving VFR aircraft to  Class C operating less than continuous is indicated by the following note:  Class D Airspace  is identified with a blue dashed line. Class D operating less than continuous is indicated by the follow - ing note: Ceilings of Class D are shown as follows:  A minus in front of the figure is used to indicate "from surface to, but not including..." Class E Surface (SFC) Airspace  is symbolized with a magenta dashed line. Class E (SFC) operating less than continu- ous is indicated by the following note: Class E Airspace  exists at 1200' AGL unless designated otherwise. The lateral and vertical  vertical limits of all Class E, (up to, but not including 18,000') are shown by narrow bands of  vignette on Sectionals and TACs. Controlled airspace floors of 700' above the ground are defined by a magenta vignette;  floors other than 700' that laterally abut uncontrolled airspace (Class G) are defined by a  blue vignette; differing floors greater than 700' above the ground are annotated by a symbol  17
