1. For preventing runway pavement structural damage, aircraft with weight equivalent to or heavier than B737 or A319 are not allowed to make 180 degree turn on the runway. The turn shall be made on the runway turn pad located near the threshold of runway 32.
2. Traffic departing runway 14 may be delayed in the apron or on the appropriate taxiway in case there is a landing traffic on runway 32.

VTSG  AD 2.21  NOISE ABATEMENT PROCEDURES

NIL

VTSG  AD 2.22  FLIGHT PROCEDURES

1.  THE CONTINUOUS DESCENT OPERATIONS (CDO) FOR ARRIVALS INTO KRABI AIRPORT
1.1 INTRODUCTION
1.1.1 As part of AEROTHAI’s ongoing efforts to improve operational efficiency and air traffic management, Continuous Descent Operations (CDO) will commence from 1700 UTC on 12 October 2017 with trial period from 1700 UTC on 11 September 2017 until 1659 UTC on 12 October 2017. 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 Krabi Airport.
1.2 CONDITION OF USE
1.2.1 Conditions for Conducting a CDO
1.2.1.1 CDO application can be either under surveillance or Procedural 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 / Final Approach point, i.e. from RWY 32 to RWY14 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 W32 inbound to Krabi Airport via STAR NEYMA1A

1.2.6 Operations Time

CDO is available 24 hours.

1.2.7 Available Runway

CDO procedure is available for RWY 32.

1.2.8 Types of Approach
1.2.8.1 ILS RWY 32
1.2.8.2 LOC RWY 32
1.2.8.3 RNAV (GNSS) RWY 32
1.2.8.4 VOR RWY 32
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 FT.250 – 320 IAS
Below 10 000 FT.220 – 250 IAS
Final Segment (up to 4 NM)160 – 180 IAS
1.2.10 Minimum Flight Altitude
1.2.10.1 Outside Krabi TMA, aircraft shall comply with altitude constraints of the CDO procedure.
1.2.10.2 Inside Krabi TMA, during CDO, minimum safety altitudes are identical to those within STAR and Instrument Approach Procedures required or minimum radar vector altitude.
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 paragraph 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 commencing descent.
1.3.4  Aircraft should descend continuously on normal arrival route to Krabi TMA.
1.3.5  Longitudinal separation required will be at least 3 minutes or 8 NM on final approach segment between CDO traffic.
1.3.6  Operations without Vectoring
1.3.6.1 ILS, LOC, RNAV (GNSS) and VOR RWY 32 Instrument Approach Procedures

Aircraft Arriving on W32

  1. Aircraft Arriving on W32, after passing 30 NM from KBI DVOR, altitude not lower than 9,000 FT., then proceed to NEYMA altitude not lower than 9,000 FT., then follow on NEYMA1A to MUNIA altitude 2,500 FT. and carry out the ILS, LOC, RNAV (GNSS) or VOR RWY 32 approach procedure as published in AIP Thailand.

  2. The pilot may request permission to fly directly to AMMIE; 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 AMMIE, altitude will be advised by ATC, after AMMIE follow on NEYMA1A to MUNIA altitude 2,500 FT. and carry out the ILS, LOC, RNAV (GNSS) or VOR RWY 32 approach procedure as published in AIP Thailand.

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 paragraph 6
1.4 PHRASEOLOGY
1.4.1 The following phraseology does not phrases and regular radiotelephony 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.
1.4.2 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”
1.4.4 Pilot-requested CDO

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

1.4.5 Approval CDO by Bangkok Area Control Centre

“(aircraft call sign), CDO (type of approach) APPROVED DESCEND TO (level or altitude), QNH (number) NEYMA1A ARRIVAL”

1.4.6 Denial CDO by Bangkok Area Control Centre
1.4.6.1  “(aircraft call sign), UNABLE TO APPROVED, DUE TO (reason)”
1.4.6.2  “(aircraft call sign), EXPECT CDO FROM KRABI APPROACH”
1.4.7 CDO Cleared or Approved by Krabi Approach Control Unit
1.4.7.1  “(aircraft call sign), CONTINUE NEYMA1A ARRIVAL CLEARED CDO (type of approach) APPROACH RWY 32, QNH (number) REPORT ESTABLISHED”
1.4.7.2  “(aircraft call sign), DESCEND TO (level), QNH (number), CDO (type of approach) APPROVED”
1.4.8  When vectoring for CDO

“(aircraft call sign), FLY HEADING (three digits); TURN LEFT (or RIGHT) HEADING (three digits) VECTORING FOR CDO, POSITION (number) MILES FROM TOUCHDOWN”

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), CDO TERMINATED DUE TO (reason)”
1.4.10 Resuming CDO

“(aircraft call sign), RESUME CDO DIRECT (point), DESCEND TO (level or altitude), QNH (number), CLEAR (type of approach) APPROACH RWY 32”

1.4.11 Pilot report leaving assigned level

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

1.4.12 Warning of aircraft below CDO Profile

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

1.5 INFORMATION/TRAINING
1.5.1 Each airline must ensure that, for each type of aircraft, pilots are aware of CDO performance requirements.
1.5.2 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 3.2° in Final Approach.
