RNP- AR in SAS RNP Approach accuracy • RNP 0.3 NM • RNP 0.15 NM
 
 
 
 RNP App advantages • Improved safety • Improved situational awareness • Improved efficiency and capacity • Slight reduction in emmissions Prosjektgruppe • LT • Avinor • SAS FOSA group • Eurocontrol • FAA observer •RNAV terminology •Regulations •Symbology •Flight Deck Procedures •Flight Crew Training RNP Generally RNAV terminology • RNAV : A comprehensive term for all types of area navigation. • B-RNAV: Basic RNAV. The requirements for B-RNAV stipulate a navigation accuracy of 5 nm from the published track for 95% of the time. B-RNAV is intended for enroute navigation in European airspace. RNAV terminology • P-RNAV : Precision RNAV. The requirements for P-RNAV stipulate a navigation accuracy of 1 nm from the published track for 95% of the time. P-RNAV is intended for terminal navigation in European airspace. Present examples of where P-RNAV is in force in Scandinavia are STAR ENBR, STAR ENZV RNAV terminology • RNP RNAV: Required Navigation Performance RNAV. RNAV with further navigation performance requirements than accuracy which guarantees that the aircraft will stay within stipulated airspace. • RNP AR: RNP Authorization:RNAV approach that require approval for specific airport from respective country authority. RNAV terminology • GPS APP A type of non precision approach using area navigation giving the lateral path for the approach. Not approved to fly in VNAV. One example is EDDM GPS approach. • APV – Approach with vertical guidance. A type of approach with vertical guidance which do not qualify as a precision approach. RNP RNAV is an APV. Regulations Requirements for RNP-RNAV operations • Aircraft must have demonstrated RNP capability • RNP RNAV qualified Flight Crew • Approved instrument approach procedure loaded from the FMC database • Operational approval in the SAS Airline AOC RNP-RNAV Approach regulations • EU-OPS 1.873 • EASA NPA 2008-14 • AMC 20-26 (RNP AR) • AMC 20-27 (RNP APCH INC APV BARPVNAV) FMC Position Update • In-flight the FMC position is continually updated from the GPS, navigation radios and IRS. • Update priority during RNAV approach – GPS – Two or more DME stations (except INN) – One VOR with a co-located DME (except INN) – IRS (except INN) Symbology Display of Navigation Source • LNAV/VNAV is displayed as navigation source when either AFDS (Autopilot Flight Director System), LNAV or VNAV mode is engaged. Lateral NPS on PFD • NPS pointer: Indicate lateral path relative to the airplane. (X-track error) • White ANP bar indicates ANP. As the ANP value increases the ANP bars extend towards the centre. • The white vertical index is fixed and represents current FMC lateral RNP
Lateral NPS on PFD • RNP on cruise is typically 2 nm. Entering airspace with lower RNP (ex. during descent Fl 150) is indicated on the MCDU and on the NPS deviation scale. The index now represents 1 nm. • The room to manoeuvre is now considerably less than before. • The RNP approach (0.3) is automatically entered as the FMC approaches the FAF or at a point programmed in the nav data base. Vertical NPS on PFD • Magenta Vertical NPS pointer indicates vertical path relative to the airplane. • Vertical ANP Bars indicate vertical ANP the same way as lateral ANP. Indications on Navigation Display Indications on Navigation Display
Flight Deck Procedures RNP RNAV approach Flight deck procedure • Complete normal approach preparations • Check that actual airport temperature is higher than minimum indicated on IAL • Select the RNAV approach procedure from DEP/ARR page • Never build your own procedure or change any values for the FAF waypoint or beyond. • Temp adjust minima RNP-RNAV Approach Flight deck procedure Check following data on LEGS page against chart. • G/P angle displayed. • Altitudes. • Track and distance from FAF to RW. • Do not use the procedure if errors are found. • LEGS Page RW32 314˚ 14NM TA601 160/ 2000 314˚ 5.9NM GP 3.00˚ RW32 123/ 102 314˚ 0.2NM (1200) - - - / 1200A 150˚ 205/ 2000 AH 205/ 2000 Flight Crew Training Qualification and Training Each pilot should recive appropriat training • Normal procedures • Abnormal procedures OPC and PC • Should include RNP procedures.
