RNAV (GNSS) RWY09

RNAV (GNSS) RWY27

UDYZ – Yerevan Intl. Airport

ICAO EUR PBN TF5

APV Workshop

23th to 27th May 2011

Strategic Objective

Improve accessibility of UDYZ by provision of an instrument

approach into RWY27

Elevate flight safety by provision of increased situational awareness

in lateral and vertical extend

Reduce fuel burn and emissions

Challenge

Initiate migration of a non-PBN airspace towards basic PBN

applications

FPSATIs a subtool of FPDAM – the integrated flight procedure development software

Uses same database

No conversions needed

No data mismatch between design and validation data

Checks how the FMS will fly the coded procedure by comparing nominal trajectory vs.

simulated trajectory retrieved from BADA database

Takes into account ARINC Path and Termination

Verifies GNSS signal quality in space

Visualization of trajectory and tunnels

Validation FPSAT – Trajectory Simulation

Benefit Analysis

Total Landings: 9783

Landings RWY27: 783

# of Missed Approaches RWY27 39

75% Improvement Target 10 Missed Approaches

Rate Missed Approach RWY27 reduced from 5% down to 1%

Benefit Analysis

75% Improvement Target is achieved byLateral guided instrument approach

Vertical assistance by using BaroVNAV based CDFA technique on RNP Approaches

Long straight in supports stabilized approach criteria

75% Improvement TargetGenerates 4% less missed approaches

Corresponds to apprx. saving of 10min flying time per missed approach

Corresponds to apprx. saving of 41.089kg fuel

Corresponds to apprx. saving of 129.430kg CO2
