CIRCULAR DE INFORMACIÓN AERONÁUTICASOBRE El USO DEL SISTEMA MUNDIAL DE DETERMINACIÓN DE LA POSICIÓN

(GPS) PARA VUELOS IFR EN LA FIR SANTO DOMINGO

AUTORIZACIÓN PARA EL USO DEL GPS 5. Se autoriza el uso del GPS en la FIR Santo Domingo como medio suplementario de Navegación en Ruta, Terminal y Aproximaciones de no-precisión; y como medio primario para Aproximaciones de no-precisión en aquellos aeropuertos donde no existan sistemas de Navegación como medio único (VOR, NDB, VOR/DME, etc.): En aquellos casos en que se requiera el uso del GPS como medio primario para Aproximaciones de no-precisión, sé deberá obtener la autorización escrita de la Dirección General dé Aeronáutica Civil previo cumplimiento de, los requisitos establecidos en el párrafo 11, literal b).

Restriction: Operators must obtain a Written authorization from the Civil Aviation Authority prior to using thisapproach procedure.

Se cumplieron todos los Requerimientos PANS-OPS Doc 8168 de la OACI.

What is Area Navigation? (RNAV)

ICAO Definition:

• A method of navigation which permits aircraft operation on any desired flight path within the coverage of the station referenced navigation aids or within the limits of the capability of self-contained aids, or a combination of these.

What is Area Navigation ?(RNAV)

• Can be viewed as a computer model

–Draws a picture of the world–Places aircrafts position on this „model world“–For accuracy several sensor inputs accepted

• Sensors

–Ground-based navigation aids (e.g. VOR, DME)–Satellite-based navigation aids (e.g. GPS)–Airborne-based navigation aids (e.g. IRS)

• 3-D position information possible, e.g. by using of four or more GPS satellites

• Quality of RNAV solution depends on quality of available sensor configuration

What is Area Navigation ?(RNAV)

RNAV system capability.• RNAV system has capability to compute distances along and across

track.• Enables aircraft to self-navigate along complex routes.• RNAV routes need not to be based on ground-based navigation

facilities.• RNAV routes may be defined by

–Runway threshold–Navaid location–Co-ordinate position–etc

• DME/DME La ubicación geográfica de las estaciones DMEs con relación a la posición de la aeronave deberán formar ángulos no menores a 30° y no mayores de 150°. La exactitud de la determinación de la posición será igual o inferior a 0.56 NM.

Potential Disadvantages of RNAV

• Reduced flexibility by inappropriately designed RNAV procedures:

– ATC and operators must be fully involved during design and implementation!

– Procedure, which is not designed to take account of ATC requirements, causes frustration.

• Mixed-mode phase during transition.• Difficult prediction of RNAV flown profiles and turns.• There is a tendency to allow an “extra” separation.

Difficult prediction of RNAV flown profiles and turns.

Benefits of RNAV– Economical

• Reduced track mileage (reduced operating costs)• Improved takeoff payload• Improved energy management• Improved track keeping• Possible reduction in number of ground based navigation facilities• Increase in runway capacity

– Environmental• Lower noise impact on noise sensitive areas• Reduction in fuel consumption• Better infrastructure planning

– Political• Increased goodwill with local authorities and neighbors• Release of non-utilized airspace for other users• Increase in coordination effectiveness with neighbors airspaces

Benefits of RNAV SID’s, STAR and APP.

• Benefits to ATC directly are:

– Less radar vectoring increases handlingcapacity

– Increase in time available for conflict solution– Reduction in monitoring required– Compensation of wind effects by clearances

to specific RNAV waypoints– Reduction in RT– Track repeatability improves inter-sector

transfers

Benefits of RNAV SID’s, STAR and APP.

• Benefits to pilots directly are:- Provides for more stabilized aircraft

approach to landing. - Reduces workload in the cockpit during

approach and landing.- Flight crew is then able to focus more

attention on responding to any other eventualities that may occur

(weather, runway conditions, etc.).
