LNAV/VNAV – Baro-VNAV
• During LNAV/VNAV, Baro-VNAV, the aircraft system uses barometric altitude to compare the vertical position of the aircraft with vertical flight path computed by the FMS, also using baro-referenced altitudes.
• The fly-by-wire Airbus aircraft are equipped with integrated LNAV/VNAV systems with accurate source of barometric altitude.
• Airbus fly-by-wire aircraft systems have been certified by EASA to conduct Baro-VNAV approaches down to a MDA/H of minimum 250ft.

In some cases, obstacle may be as close as 2xRNP.Need to demonstrate a
Target Level of Safety of 10-7/approach
Including the effect of system failures
Existing airborne systems are not capableto meet this objective alone
Operational mitigations are required to achieve the overall safety objectives (FOSA)

FMS Landing System (FLS)
FLS is a new way to fly NPA – not a new type of approach
• Airbus has decided to modify the current cockpit design for Non Precision Approach operational procedures to provide similar interface for Non Precision Approach as for Precision Approach (ILS Look alike)
• This new design allows conducting existing non precision approaches (VOR, VOR/DME, NDB, NDB/DME, GPS) in the same manner as Precision Approach (ILS/GLS) with similar display, guidance & warnings.
•This function is autonomous and does not require any additional information from the ground.
•Applies to straight in approach flight path.

FLS Principle • Based on database stored data, an FLS
approach beam is defined. Then, lateral and vertical deviations between the FLS beam and the computed aircraft position are computed by the MMR and used for guidance and display to the pilot.

FLS Benefits
• Stabilized approachEnhanced safety operation:
– 80% of approach accidents occur on non stabilized approachesFLS available all over the world:
– non precision approaches published on any airport in the world
• ILS Look alikeHMI close to precision approachesReuse of ILS pilot skills , reduction in training needs.Use of ILS guidance laws in Flight Guidance: same behavior as precision approachesTemperature compensated

Conclusion
Satellite based systems and RNP operations foreseen as the final successor to ground based aids.
Airbus supports the development of new landing systems in line with operator requirements.
MLS, FLS, SBAS (SLS)MMR is the key to enable all approaches (precision and non precision) to be flown the same way.
RNP AR : most of the fly by wire a/c are RNP AR capable.Airbus has already met more stringent EASA requirementsReduced operational demonstration for airlinesHigher confidence from national authorities
