VTSF  AD 2.21  NOISE ABATEMENT PROCEDURES

NIL

VTSF  AD 2.22  FLIGHT PROCEDURES

1.  The Continuous Descent Opertions (CDO) for arrivals into Nakhon Si Thammarat Airport
1.1 Introduction
1.1.1 CDO is an operation, enabled by airspace design, procedure design and ATC facilitation, in which an aircraft descends continuously, to the greatest possible extent, by employing minimum engine thrust, ideally in a low drag configuration, prior to Final Approach Fix / Final Approach Point.
1.1.2 Vertical profile of CDO aims to improve flight stability (minimal level-off), increase terrain safety, ensure environmental friendly procedures by reducing aircraft noise, fuel consumption and emissions, enhanced flight punctuality and predictability, as well as other economic benefits for flights into Nakhon Si Thammarat Airport.
1.2 Condition of Use
1.2.1 Conditions for Conducting a CDO
1.2.1.1 CDO application must be under surveillance environment.
1.2.1.2 CDO can be requested by pilot or initiated by ATC. Pilot should request CDO at least 5 minutes prior to reaching Top of Descent (TOD) for any type of approach.

Note: 1. There is limited benefit if CDO clearance is received at altitude lower than 10,000 FT.

Note: 2. In case of CDO procedure being impractical due to an emergency, weather condition, traffic situation or any other reasons, an alternate instruction will be issued by ATC, or requested by pilot.

1.2.2 Application of Other ATC Procedures
1.2.2.1 When conducting CDO, standard ATC procedures continue to apply. ATC may issue clearance to an intermediate approach level while facilitating a CDO profile.
1.2.2.2 In doing so, ATC shall endeavour to issue further descent clearance prior to the CDO flight reaching the last assigned altitude so as to prevent aircraft from levelling off.
1.2.3 Change of Runway-In-Use
1.2.3.1 In case of change on Runway-in-Use prior to aircraft reaching Final Approach Fix, i.e. from RWY19 to RWY01 CDO procedure shall be cancelled.
1.2.3.2 Pilot should then re-plan arrival route to the revised landing runway and inform ATC if the flight would still be able to meet all required speed/altitude restrictions.
1.2.4 Aircraft Type

CDO procedure is applicable for FMS capable aircraft.

1.2.5 Arrival Routes

CDO procedure is in place for all aircraft on W35 inbound from Bangkok to Nakhon Si Thammarat Airport.

1.2.6 Operations Time

CDO is available 24 hours.

1.2.7 Available Runway

CDO procedure is available for RWY19

1.2.8 Types of Approach
1.2.8.1 ILS or LOC z RWY19
1.2.8.2 RNAV (GNSS) RWY19
1.2.9 Speed

When traffic permits, aircraft will operate at an optimum speed calculated by FMS, depending on aircraft type. The following speed guidance should be applicable in case of high traffic volume.

Flight StatusSpeed Range
Above 10 000 FT250 - 320 IAS
Below 10 000 FT220 - 250 IAS
Final Segment (up to 4 NM)160 - 180 IAS
1.2.10 Minimum Flight Altitude
1.2.10.1 Outside NKS TMA, aircraft shall comply with altitude constraints of the CDO procedure.
1.2.10.2 During CDO, minimum safety altitudes are identical to those within Instrument Approach Procedures requested.
1.3 CDO Procedure
1.3.1 Before aircraft reaching TOD (approximately 150 NM from the airport), either pilot or ATC can initiate CDO using phraseologies described in para 1.4.
1.3.2 When all requirements for CDO are met and situation permits, CDO will commence.
1.3.3 Pilot shall operate aircraft FMS to plan optimal descent profile and report CDO execution Nakhon Si Thammarat commencing descent.
1.3.4 Aircraft should descend continuously on normal arrival route to NKS TMA.
1.3.5 Longitudinal separation required will be at least 5 minutes (15 NM) between CDO traffic.
1.3.6 Operations without Vectoring
1.3.6.1 ILS or LOC z RWY19 Procedure
1.3.6.1.1 Aircraft Arriving on W35
After passing, 20 NM from NKS DVOR, altitude not lower than 8,000 FT., then proceed to TAWIT, altitude not lower than 5,000 FT. and follow ILS or LOC z RWY19 procedure, or
The pilot may request permission to fly directly to (IF); however, this would be an ATC’s jurisdiction whether the request can be approved, depending on traffic conditions. In this case, the pilot shall fly directly to (IF) altitude 3,000 FT., and cross 20 NM from NKS DVOR, altitude not lower than 8,000 FT., following the ILS or LOC z RWY19 procedure.

Note: CDO will be operated within radar coverage.

1.3.6.2 RNAV (GNSS) RWY19 Procedure
1.3.6.2.1 Aircraft Arriving on W35
After passing, 20 NM from NKS DVOR, altitude not lower than 8,000 FT., then proceed to TAWIT, altitude not lower than 5,000 FT. and follow the RNAV(GNSS) RWY19 procedure, or
The pilot may request permission to fly directly to (IF); however, this would be an ATC’s jurisdiction whether the request can be approved, depending on traffic conditions. In this case, the pilot shall fly directly to (IF) altitude 3,000 FT., and cross 20 NM from NKS DVOR, altitude not lower than 8,000 FT., following the RNAV (GNSS) RWY19 procedure.

Note: CDO will be operated within radar coverage.

1.3.7 Operations under Vectoring
1.3.7.1 Pilot should receive CDO clearance at altitude not lower than 10,000 FT.
1.3.7.2 ATC shall provide vectoring guidance and track mile estimate to pilot.
1.3.8 Radio Communications Failure
1.3.8.1 In the event of radio communication failure, CDO flight will be terminated immediately.
1.3.8.2 Pilot is to apply radio failure procedures stated in AIP Thailand ENR 1.6-6 para 6
1.4 Phraseology
1.4.1 The following phraseology enables clear and concise communications between pilot and controller to maintain safety of CDO arrivals.
1.4.2 ATC-initiated CDO

“(aircraft call sign), (ATC unit), CDO AVAILABLE, DO YOU ACCEPT?”

1.4.3 Pilots response to ATC-initiated CDO
1.4.3.1 “(aircraft call sign), ACCEPT CDO”
1.4.3.2 “(aircraft call sign), NEGATIVE CDO”

1.4.8 When vectoring for CDO

“(aircraft call sign), VECTORING FOR CDO, FLY HEADING (number) DESCEND [(level) or (altitude), QNH (number)], TRACK MILE (number)”

1.4.9 CDO Cancellation
1.4.9.1 “(aircraft call sign), CANCEL CDO DUE TO (reason), (STOP) DESCEND [ (level) or (altitude), QNH (number)]”
1.4.9.2 “(aircraft call sign), DUE TO (reason), CDO IS NOW TERMINATED”
1.4.10 Resuming CDO

“(aircraft call sign), RESUME CDO, DCT (point), DESCEND [(level) or (altitude), QNH (number)], CLEARED (type of approach) APPROACH”

1.4.11 Pilot report leaving
