8/15/19  Pilot/Controller Glossary  service in this airspace is delegated to various  countries, based generally upon geographic proxim- ity and the availability of the required resources.  OCEANIC ERROR REPORT- A report filed when  ATC observes an Oceanic Error as defined by FAA  Order 7110.82, Reporting Oceanic Errors.  OCEANIC PUBLISHED ROUTE- A route estab- lished in international airspace and charted or  described in flight information publications, such as  Route Charts, DOD En route Charts, Chart  Supplements, NOTAMs, and Track Messages.  OCEANIC TRANSITION ROUTE- An ATS route  established for the purpose of transitioning aircraft  to/from an organized track system.  ODP- (See OBSTACLE DEPARTURE PROCEDURE. ) OFF COURSE-  A term used to describe a situation  where an aircraft has reported a position fix or is  observed on radar at a point not on the ATC-approved  route of flight.  OFF-ROUTE VECTOR- A vector by ATC which  takes an aircraft off a previously assigned route.  Altitudes assigned by ATC during such vectors  provide required obstacle clearance.  OFFSET PARALLEL RUNWAYS- Staggered  runways having centerlines which are parallel.  OFFSHORE/CONTROL AIRSPACE AREA- That  portion of airspace between the U.S. 12 NM limit and  the oceanic CTA/FIR boundary within which air  traffic control is exercised. These areas are  established to provide air traffic control services.  Offshore/Control Airspace Areas may be classified  as either Class A airspace or Class E airspace.  OFT- OM- ON COURSE- (See OUTER FIX TIME.)  (See OUTER MARKER.)  a.  Used to indicate that an aircraft is established on  the route centerline.  b.  Used by ATC to advise a pilot making a radar  approach that his/her aircraft is lined up on the final  approach course.  (See ON-COURSE INDICATION.)  ON-COURSE INDICATION- An indication on an  instrument, which provides the pilot a visual means  of determining that the aircraft is located on the  centerline of a given navigational track, or an  indication on a radar scope that an aircraft is on a  given track.  ONE-MINUTE WEATHER- The most recent one  minute updated weather broadcast received by a pilot  from an uncontrolled airport ASOS/AWOS.  (See DUE REGARD.)  (See OCEANIC NAVIGATIONAL ERROR  REPORT.)  ONER- OPERATIONAL- OPERATIONS SPECIFICATIONS [ICAO]- The  authorizations, conditions and limitations associated  with the air operator certificate and subject to the  conditions in the operations manual.  OPPOSITE DIRECTION AIRCRAFT- Aircraft are  operating in opposite directions when:  a.  They are following the same track in reciprocal  directions; or  b.  Their tracks are parallel and the aircraft are  flying in reciprocal directions; or  c.  Their tracks intersect at an angle of more than  135 .  OPTION APPROACH- An approach requested and  conducted by a pilot which will result in either a  touch-and-go, missed approach, low approach,  stop-and-go, or full stop landing. Pilots should advise  ATC if they decide to remain on the runway, of any  delay in their stop and go, delay clearing the runway,  or are unable to comply with the instruction(s).  (See CLEARED FOR THE OPTION.)  (Refer to AIM.)  ORGANIZED TRACK SYSTEM- A series of ATS  routes which are fixed and charted; i.e., CEP,  NOPAC, or flexible and described by NOTAM; i.e.,  NAT TRACK MESSAGE.  PCG O-2
