South African Airways (SAA) has received approval from the South African Civil Aviation Authority (SACAA) for the implementation of newly obligatory navigation performance with authorisation required (RNP AR) procedures at Cape Town International Airport.
The new procedures have been created in close cooperation between SAA and Airbus’ subsidiary Quovadis, together with SACAA and air traffic and navigation services (ATNS).
The approval will clear ways for further development of RNP AR procedures in the country, which would enhance safety and boost operational efficiency.
Quovadis COO Don-Jacques Ould-Ferhat said: "Our collaboration has produced safe and fuel-efficient flight procedures for SAA at Cape Town Airport."
RNP AR procedures comply with SAA’s operations and are aimed at offering shorter tracks over conventional procedures, as well as reducing flight times and fuel burn on each approach and departure track.
These procedures use flight tracks derived from already operational visual tracks through Cape Town’s complex airspace and allow flying shorter tracks even during instrument meteorological conditions (IMC).
SAA Flight Operations director Johnny Woods said that the move allows South Africa to widely deploy PBN procedures in line with ICAO recommendations.
"We look forward to future implementations and procedure design." Woods said
As part of the project, new RNP AR Engine Out Standard Instrument Departures (EOSIDs) have been designed to offer a fully-guided and protected track to be followed when an engine fails to operate at takeoff.
The new procedures also offer additional benefits such as RNP 0.3 accuracy level that provides lower approach minima.
As part of the project, SAA implemented new airline procedures, data management processes and flight crew training on the new RNP AR procedures at Cape Town, while Quovadis helped SAA, SACAA and ATNS during the RNP AR approval process.
