Airbus RNP Operations 7 Implementing RNP, October 4-5 2005
RNAV in Terminal Area
The radio navaid infrastructure supports the required
Navigation Accuracy level
– It is not the Operator’s duty to verify the adequacy of radio navaid
coverage
– Inadequate radio navaid coverage should be notified by NOTAM or
on the instrument procedure chart ⇒ GPS required
GPS acceptable if TSO C 129A certified
– All Airbus with GPS comply
Single or Dual RNAV system
– Single system acceptable, unless flight path below area MSA
or/and (?) no radar coverage (TGL 10)
– Should be stated on the instrument procedure chart

Airbus RNP Operations 8 Implementing RNP, October 4-5 2005
RNAV in Terminal Area
Operational Approval:
Aircraft capability
– Stated in the AFM
Crew documentation
– OPS Manual based on FCOM
– MEL
Crew training
– RNAV system knowledge
– Briefing on RNP RNAV
Navigation database integrity
– Approved database suppliers
– Operator’s validation
Navigation Database
validation was the main
challenge to deploy P-RNAV.
The main database providers
are now ED76/D0200A
compliant

Airbus RNP Operations 10 Implementing RNP, October 4-5 2005
RNAV in approach
RNAV (GNSS) “Sensor related”
RNP RNAV “Performance related”
– RNP 0.3,
– Straight final segment
DA as low as 250 ft AGL
with FINAL APP mode
(LNAV/VNAV ) guidance
A large part of the Airbus world fleets can
fly instrument approach procedures
published under ICAO PANS OPS (or
TERPS) criteria.
A lot of destinations could benefit from the
implementation of such procedures.

• Final descent at a constant Flight Path Angle to a DA
• Stabilized approach leading 50 ft above runway threshold
• Accuracy of navigation

• All Airbus with an FMS and
GPS are capable to fly such
RNAV Approaches
The Advantages of RNAV Approaches
• All Airbus with FMS 2 can
fly in addition RF legs
Since mid-80’s, Airbus
promotes a constant slope
NPA rather than step-down
(“dive and drive”) procedures
This is in line with the CDFA
concept (NPA OPS-41)

RNAV in Approach
It is now time to take benefit of Airbus aircraft
RNAV capabilities in approach
“PANS OPS” straight in RNP 0.3 RNAV or RNAV(GNSS)
approaches can easily be implemented:
Deletion of circling procedures
Deletion of “old style” NPAs
Access to new destinations
