RNP AR APCH in Hong Kong

• Introduction of RNP AR APCH in Hong Kong

• Procedure for Grant of the Approval

• Case Highlight

• Foreign Operators approval


PBN Development

� 1990s – ICAO Special Committee on Future Air Navigation

Systems (FANS) developed the concept on RNP

Capability (RNPC) and later became RNP

� 2003 - Review RNP → PBN concept for global

harmonization

� Today - ICAO urged all states to implement RNAV

ATS route and approach procedures with PBN

concept:

• Complete the PBN plan by 2009

• Complete all the implementation by 2016


Introduction of RNP AR APCH in Hong Kong

To comply with the ICAO implementation

requirements,

Hong Kong CAD’s

Air Traffic Management Division (ATMD)

is going to

� Publish the RNP AR APCH procedures for HKIA

in FEB 2010

� Effective in APR 2010

1 Aircraft eligibility

a) For new aircraft.- the aircraft qualification documentation can be

approved by the CAA as part of an aircraft certification project, and will be reflected in the AFM and related documents.

b) For aircraft in use.- Documentation produced by the manufacturer.

2 Aircraft qualification

a) The AFM or other aircraft qualification evidence shall indicate the

normal and abnormal flight crew procedures, failure alerting

responses, and any other limitation, including information related to

the operating modes required for flying an RNP AR APCH procedure.3 Navigation sensors.- On the horizontal plane, the RNP equipment will

use data input from the following types of position sensors, but with the

GNSS as primary positioning basis:

a) Global navigation satellite system (GNSS).

b) Inertial navigation system (INS) or inertial reference system (IRS), with automatic position updating from suitable radio-based navigation

equipment.

c) Distance-measuring equipment (DME) that provides measurements

from two or more ground stations (DME/DME)

(AMC 20-26,

par )

3 Action to be taken at the DA.-Visual or Missed Approach

4 Temperature limitation.-

The temperature limitation will be shown through a note in the

instrument approach procedure. If the aircraft system is capable of

temperature compensation, the crew must follow the operator procedures

based on the manufacturer instructions.

5 VNAV Path Mode Selection.-Correct Selection of the Vertical mode(s).


Topics Operating Procedures (Highlighted Points)

MEL:-E.g. EGPWS/TAWS is required for all RNP AR APCH

Autopilot (AP) and flight director (FD).-For procedures with a navigation precision of less than RNP 0.3 or with RF legs.

NAVAID Exclusion.-

By using NOTAM information.

Validation of Navigation Database.-

Pilots must confirm the NAV Database is valid.


PART 4 - BASIC PILOT PROCEDURES FOR RNP AR APCH OPERATIONS



Topics Operating Procedures (Highlighted Points)

Track deviation monitoring.-Pilots must use a lateral deviation indicator, an FD and/or an AP in lateral navigation mode

during RNP AR APCH procedures

Procedures with RF legs.-

An RNP AR APCH procedure may require aircraft to have the capability of executing an RF leg

to avoid terrain and obstacles. Since not all aircraft have this capability, flight crews must

know if they can or cannot carry out these procedures.

Altimeter cross-check.-

Prior to the FAF, but not before the IAF, the flight crew must carry out a cross-check of both

pilot altimeters to make sure they agree within 100 ft.

Engine Out Procedure.-

Aircraft may demonstrate the Flight Technical Error (FTE) and other required performance

within limit. It may continue the RNP AR APCH.


PART 4 - BASIC PILOT PROCEDURES FOR RNP AR APCH OPERATIONS

ICAO DOC 9613 Vol II Part C para 6.3.3.3.1.3

a) The navigation system must provide the capability to

continuously display to the pilot flying, on the primary

flight instruments for navigation of the aircraft, the aircraft

position relative to the RNP defined path (both lateral and

vertical deviation).

m) The navigation system must provide a numeric display

of the vertical deviation with a resolution of 3m (10 ft) or

less, and the lateral deviation with a resolution of 0.01 NM

or less.

Once approval is received from the State of Registry

(Hong Kong CAD), operators desiring to perform RNP AR

APCH operations in other States (e.g. China, United States

etc.) will require authorization from that State Authority.

39

Foreign Operators approval


In Hong Kong, CAD is considering to develop procedures &

requirements to accept approval granted by other state

authority of foreign operators to conduct RNP AR APCH at

Hong Kong.

As a minimum:

• State Approval

• Fleet / Aircraft Specific

• Documentary Evidence
