VTCN  AD 2.20  LOCAL AERODROME REGULATIONS

To prevent runway pavement damage which may result in the closure of the aerodrome if such damage is severe, aircraft code letter C or higher shall make 180 degrees turn at the runway turn pads located on left side of runway 20 (near the threshold of runway 20). Any breach done by the aircraft operator shall be recorded and reported to The Civil Aviation Authority of Thailand/the Headquarters of that operator and shall be liable for the compensation caused by such violation

VTCN  AD 2.21  NOISE ABATEMENT PROCEDURES

NIL

VTCN  AD 2.22  FLIGHT PROCEDURES

1.  IMPLEMENTATION OF THE CONTINUOUS DESCENT OPERATIONS (CDO) FOR ARRIVALS INTO NAN NAKHON AIRPORT
1.1 Condition of Use
1.1.1 Conditions for Conducting a CDO
1.1.1.1 CDO application can be either under Surveillance or Procedural environment.
1.1.1.2 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.

1.1.2 Application of Other ATC Procedures
1.1.2.1 When conducting CDO, standard ATC procedures continue to apply. ATC may issue clearance to an intermediate approach level while facilitating a CDO profile.
1.1.2.2 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.
1.1.3  Change of Runway-In-Use
1.1.3.1 In case of change on Runway-in-Use prior to aircraft reaching to Intermediate Fix (IF), i.e. from RWY02 to RWY20 CDO procedure shall be cancelled.
1.1.3.2 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.
1.1.4 Aircraft Type

CDO procedure is applicable for FMS capable aircraft.

1.1.5 Arrival Routes

CDO procedure is in place for all aircraft on W29 inbound to Nan Nakhon Airport.

1.1.6 Operations Time

CDO is available 24 hours.

1.1.7  Available Runway

CDO procedure is available for RWY02

1.1.8 Types of Approach
1.1.8.1  ILS or LOC z RWY02
1.1.8.2 ILS or LOC y RWY02
1.1.9 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 FT. 250 – 320 IAS
Below 10 000 FT.220 – 250 IAS
Final Segment (up to 4 NM)160 – 180 IAS
1.1.10 Minimum Flight Altitude
1.1.10.1 Outside NAN TMA, aircraft shall comply with altitude constraints of the CDO procedure.
1.1.10.2 Inside NAN TMA, during CDO, minimum safety altitudes are identical to those within Instrument Approach Procedures required
1.2 CDO Procedure
1.2.1 Before aircraft reaching TOD (approximately 100 NM from the airport), either pilot or ATC can initiate CDO using phraseologies described in paragraph 1.3.
1.2.2 When all requirements for CDO are met and situation permits, CDO will commence.
1.2.3 Pilot shall operate aircraft FMS to plan optimal descent profile and report CDO execution commencing descent.
1.2.4 Aircraft should descend continuously on normal arrival route to NAN TMA.
1.2.5 Longitudinal separation required will be at least 10 minutes between CDO traffic.
1.2.6 CDO Operations
1.2.6.1 Fully ILS or LOC z RWY 02 and ILS or LOC y RWY02

Aircraft Arriving on W29

Aircraft Arriving on W29 after passing, DUGEL 20 NM from NAN DVOR, altitude not lower than 7,000 FT., or above, then proceed to ASUBI altitude not lower than 5,000 FT., or above and follow the ILS or LOC z RWY02 procedure as published in AIP Thailand.

1.2.6.2 Direct IF for ILS or LOC z RWY02 and DCT IF for ILS or LOC y RWY02

Aircraft Arriving on W29

The pilot may request permission to fly directly to Intermediate Fix (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), and cross 25 NM from NAN DVOR, altitude not lower than 8,000 FT., and cross IF altitude not lower than 6,800 FT., following the ILS or LOC z RWY02 or ILS or LOC y RWY02 procedure as published in AIP Thailand.

1.2.7 Radio Communications Failure
1.2.7.1 In the event of radio communication failure, CDO flight will be terminated immediately.
1.2.7.2 Pilot is to apply radio failure procedures stated in AIP Thailand ENR 1.6-7 paragraph 6.
1.3 Phraseology
1.3.1 The following phraseology does not phrases and regular radio telephony procedure words contain in Doc 4444 and Doc 9432, but it enables clear and concise communications between pilot and controller to maintain safety of CDO arrivals.
1.3.2 ATC-initiated CDO

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

1.3.3 Pilots response to ATC-initiated CDO
1.3.3.1 “(aircraft call sign), ACCEPT CDO”
1.3.3.2 “(aircraft call sign), NEGATIVE CDO”
1.3.4 Pilot-requested CDO

“(ATC Unit), (aircraft call sign), REQUEST CDO (type of approach) APPROACH”

1.3.5  Approval CDO by Bangkok Area Control Centre

“(aircraft call sign), CDO (type of approach) APPROVED DESCEND TO (level or altitude), QNH (number)”

1.3.6 Denial CDO by Bangkok Area Control Centre
1.3.6.1 “(aircraft call sign), UNABLE TO APPROVED, DUE TO (reason)”
1.3.6.2 “(aircraft call sign), EXPECT CDO FROM NAN APPROACH”
1.3.7 CDO Cleared or Approved by NAN Approach Control Unit
1.3.7.1 “(aircraft call sign), CDO DESCEND TO (level or altitude), QNH (number), INFORMATION…CURRENT EXPECT (type of approach) APPROACH RWY (number)”
1.3.7.2 “(aircraft call sign), DESCENT TO (level) QNH (number) CDO (type of approach) APPROVED”
1.3.8 CDO Cancellation
1.3.8.1 “(aircraft call sign), CANCEL CDO DUE TO (reason), STOP DESCEND (level or altitude), QNH (number)”
1.3.8.2 “(aircraft call sign), CDO TERMINATED DUE TO (reason)”
1.3.9 Resuming CDO

“(aircraft call sign), RESUME CDO DIRECT (point), DESCEND TO (level or altitude), QNH (number), CLEAR (type of approach) APPROACH RWY02”

1.3.10  Pilot report leaving assigned level

“(aircraft call sign), CDO LEAVING (level)”

1.3.11 Warning of aircraft below CDO Profile

“(aircraft call sign), BELOW CDO PROFILE, ALTITUDE SHOULD BE (altitude) OR ABOVE”

1.4 Information/Training
1.4.1 Each airline must ensure that, for each type of aircraft, pilots are aware of CDO performance requirements.
1.4.2 Airlines are expected to define strategy to be adopted to drag-generating parts extension to stabilize aircraft in landing configuration at an altitude in compliance with flight safety, taking into account glide path at 3.4° in Final Approach.
