Pilot Briefing Information. The current format for charted  IAPs issued by Aeronautical Information Services. The  information is presented in a logical order facilitating  pilot briefing of the procedures. Charts include formatted  information required for quick pilot or flight crew reference  located at the top of the chart.  Point-in-Space (PinS) Approach. An approach normally  developed to heliports that do not meet the IFR heliport  design standards but meet the standards for a VFR  heliport. A helicopter PinS approach can be developed  using conventional NAVAIDs or RNAV systems. These  procedures have either a VFR or visual segment between the  MAP and the landing area. The procedure specifies a course  and distance from the MAP to the heliport(s) and includes a  note to proceed VFR or visually from the MAP to the heliport,  or conduct the missed approach.  Positive Course Guidance (PCG). The continuous display  of accurate course and flight path data that enables a pilot  to precisely fly along a specific track or course using RNAV,  a ground-based NAVAID or a radar vector. For RNAV or a  ground-based NAVAID, the guidance is displayed in the  aircraft; for a radar vector, the guidance data is displayed  in the radar facility  Reduced Vertical Separation Minimums (RVSM). RVSM  airspace is where air traffic control separates aircraft by  a minimum of 1,000 feet vertically between flight level  (FL) 290 and FL 410 inclusive. RVSM airspace is special  qualification airspace; the operator and the aircraft used  by the operator must be approved by the Administrator.  Air traffic control notifies operators of RVSM by providing  route planing information.  Reference Landing Speed (V$_{REF}$). The speed of the aircraft,  in a specified landing configuration, at the point where it  descends through the 50-foot height in the determination  of the landing distance.  Precision Runway Monitor (PRM). Provides air traffic  controllers with high precision secondary surveillance  data for aircraft on final approach to parallel runways that  have extended centerlines separated by less than 4,300  feet. High resolution color monitoring displays (FMA) are  required to present surveillance track data to controllers  along with detailed maps depicting approaches and a no  transgression zone.  Remote Communications Outlet (RCO). An unmanned  communications facility remotely controlled by air traffic  personnel. RCOs serve FSSs and may be UHF or VHF. RCOs  extend the communication range of the air traffic facility.  RCOs were established to provide ground-to-ground  communications between air traffic control specialists  and pilots located at a satellite airport for delivering en  route clearances, issuing departure authorizations, and  acknowledging IFR cancellations or departure/landing  times.  Reporting Point. A geographical location in relation  to which the position of an aircraft is reported. (See  Compulsory Reporting Points).  Required Navigation Performance (RNP). RNP is a statement  of the navigation performance necessary for operation  within a defined airspace. On-board monitoring and  alerting is required.  RNAV DP. A Departure Procedure developed for RNAV- equipped aircraft whose ground track is based on satellite  or DME/DME navigation systems.  Roll-Out RVR. The RVR readout values obtained from  sensors located nearest the rollout end of the runway.  Preferential Departure Route (PDR). A specific departure  route from an airport or terminal area to an en route point  where there is no further need for flow control. It may be  included in an instrument Departure Procedure (DP) or a  Preferred IFR Route.  Preferred IFR Routes. A system of preferred IFR routes  guides you in planning your route of flight to minimize  route changes during the operational phase of flight, and  to aid in the efficient orderly management of air traffic  using federal airways.  Runway Heading. The magnetic direction that corresponds  with the runway centerline extended, not the painted  runway numbers on the runway. Pilots cleared to “fly or  maintain runway heading” are expected to fly or maintain  the published heading that corresponds with the extended  centerline of the departure runway (until otherwise  instructed by ATC), and are not to apply drift correction  (e.g., RWY 4, actual magnetic heading of the runway  centerline 044.22°, fly 044°).  Principal Operations Inspector (POI). Scheduled air carriers  and operators for compensation or hire are assigned a POI  who works directly with the company and coordinates FAA  operating approval.
