LNAV/VNAV Baro-VNAV During LNAV/VNAV, Baro-VNAV, the aircraft system usesbarometric 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 integratedLNAV/VNAV systems with accurate source of barometric altitude. AIRBUS S.A.S. All rights reserved. Confidential and proprietary document.

Airbus fly-by-wire aircraft systems have been certified byEASA to conduct Baro-VNAV approaches down to a MDA/H of minimum 250ft.

FMS Landing System (FLS) 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 is a new way to fly NPA not a new type of approachICAO LVP&APV workshop June 09 Page 17

FLS Principle Based on database stored data, an FLSapproach 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.The FLS virtual beam is defined by: Anchor Point Course Slope FLS beam FAF Anchor PointSlope

FLS Benefits Stabilized approachEnhanced safety operation: 80% of approach accidents occur on non stabilized approaches

FLS available all over the world: non precision approaches published on any airport in the world
