8 OPERATIONAL APPROVAL
The process to obtain an operational approval will be initiated by an application sent by the
airline to its national authorities.
The application should describe the project and the strategy chosen by the airline to comply
with the applicable regulation.
The project may have quite different implications depending the type of RNP AR (demanding
or not demanding) that is envisaged or if the project is to fly an existing public procedure or to
develop a private (or tailored) procedure.
The airline with its national authorities will need to determine the aircraft equipment and the
level of aircraft certification adequate for the intended type of RNP AR operations. The level
of operational requirements and the way the national authorities will supervise how the airline
comply, may influence this decision.
For “demanding” RNP AR operations, the full RNP AR certification is required, and the aircraft
definition and operational requirements are defined in the ACD referenced in the Flight
Manual.
For “limited” (Not demanding) RNP AR operations, the “basic” RNP certification may be
considered as sufficient. The required aircraft definition and the operational requirements are
defined in the SCOC document.
The operational evaluation will need to be reviewed by the national authorities, as it may
induce specific operational requirements.
The overall check of the aircraft capability to fly the intended procedure, but also that the flight
crew procedures and training are adequate, will be made during one (or more) validation
flight(s) in good weather conditions.

8.2 AIRBUS OPERATIONAL SUPPORT
The airline has the ownership of its RNP AR project. It will require the full commitment of the
airline organization from executive management to the flight operations and training at all
levels.
An RNP AR project cannot be “bought” out of the shelf, but the airline may expect support
from Airbus and selectected service providers.
The areas where Airbus can provide assistance is indicated in green in the above schematic.
The area where the airline may need to seek the support of a service provider is underlined in
yellow.
For the design of private (tailored) RNP AR procedures, the airline will usually need to contract
such a support.
Airbus is already working with such organizations for different projects and can put the airline
in contact with selected providers.
To be succesfull, the project will require close coordination between the airline the service
