1.1 This AIP Supplement informs aircraft operators and pilots of new departure and arrival procedures for Runway 02R and 20L, as well as revisions to existing procedures for departures and arrivals to include Runway 02R and 20L, effective from 03 December 2020 0000UTC.
1.2 Revision to existing procedures for departures and arrivals
1.3 New departure and arrival procedures for Runway 02R and 20L
2.1 Low Level Holding Areas
2.1.1 With the operationalization of Runway 02R and 20L, the existing low level holding areas at SAMKO and NYLON for procedural traffic landing at Singapore Changi Airport as described in AIP Singapore, ENR 1.5 paragraph 1.3.1 a. and b. will be revised to include Runway 02R and 20L as follows:
2.2 RNAV-1 STARs for RWY 02 and 20
2.2.1 The existing Changi Instrument Flight Procedure (IFP) STAR charts published in AIP Singapore are listed in section WSSS AD 2.24. Runway 02R and 20L have been added to these existing IFP STAR charts (refer to Appendix A).
2.2.2 The existing Changi IFP STARs were designed to be only runway direction specific (i.e. it does not serve a specific runway for the given direction). Pilots can expect ATC vectors to the respective Instrument Approach Procedures (IAPs) before reaching the last waypoint on the STAR.

2.3 Vessel Movement affecting instrument approaches on Runway 02 and 20
2.3.1 This section will supersede the information published in AIP Singapore, ENR 1.5 paragraph 2.5 and 2.6.
2.3.2 There are possible tall vessel movements in waters around Singapore Changi Airport. As these mobile vessels vary in height and location, they are only indicated as “possible vessel" obstacles in the instrument approach charts.
2.3.3 Information on the heights of these tall vessels are relayed to ATC by the Maritime and Port Authority of Singapore. ATC will advise arriving aircraft of any restrictions on the types of instrument approaches and landing runway.
2.4 Vessel Movement Advisories for Runway 02 Departures
2.4.1 This section will supersede the information published in AIP Singapore, ENR 1.5 paragraph 3.2b, 3.3b and 3.5.
2.4.2 Values in the table below are calculated based on a nominal climb gradient of 3.3% and will provide the required obstacle clearance with vessel movements along the northern shipping channel. ATC will advise departing aircraft on respective runways when the vessel height is above these values:
| Departure | No advice from ATC if the vessels are at or below the following heights with respect to their departure runways |
|---|---|
| 02L | 35m (AMSL) or below |
| 02C | 70m (AMSL) or below |
| 02R | 65m (AMSL) or below |
2.4.3 Aircraft operators shall calculate their own climb gradients based on actual lift off point to ensure enough clearance with the vessels crossing the northern shipping channel. The calculation will have to ensure the following:
Note: The calculated climb gradient shall not be lower than the procedure climb gradient for departures (refer to paragraph 3.2.2 below and published in AIP Singapore, ENR 1.5 paragraphs 3.2 a. and 3.3 a.)
2.4.4 For the above calculations, aircraft operators shall use the distance information for the various departure runways as follows:
| DEP RWY | 02L | 02C | 02R |
|---|---|---|---|
| Distance | 1100m | 2590m | 2310m |
Note: The distance for departure Runways 02L, 02C and 02R are measured from the DER to the shipping channel north of Changi.
2.5 Total Radio Failure – Special Procedures – Singapore Changi Airport – Arrivals

2.6 Identification of Runway-in-use
2.6.1 As per AIP Singapore, ENR 1.6 paragraph 1.11, ATC will switch on the appropriate approach lights and the ILS serving the runway-in-use to assist the pilot in its identification. If the approach lights for the runway-in-use are sighted but the ILS frequency is not received, the pilot shall assume that the ILS is inoperative and shall proceed to land on the runway on which the approach lights have been sighted.
2.6.2 If unable to land within 30 minutes of EAT or ETA, if no EAT has been received and acknowledged, proceed in accordance with AIP Singapore, ENR 1.6 paragraph 1.8.3 d.
2.7 Total Radio Failure – Special Procedures – Singapore Changi Airport – Departures

2.7.2 Existing radio communication failure procedures for RWY 20R/20C departures published in AIP Singapore ENR 1.6 paragraph 1.12.3 will be applicable for RWY 20L departures.
3.1 Instrument Approach Procedures
3.1.1 Required Navigation Performance (RNP) procedures were designed for Runway 02R and 20L in accordance with criteria RNP APCH procedures using barometric vertical navigation as stipulated in the ICAO PANS-OPS (Doc 8168) Volume II and ICAO Manual of PBN (Doc 9613).
3.1.2 The RNP procedures can be flown as a Non-Precision Approach (NPA) down to Lateral Navigation (LNAV) minima or an Approach with Vertical Guidance (APV) using barometric vertical navigation (BaroVNAV) down to LNAV/VNAV minima. Details of the procedures can be found in Appendix B of this AIP Supplement as follows:
| Instrument Approach | AIP SUP Reference |
|---|---|
| RNP RWY 02R | Appendix B-1 to B-1.1 |
| RNP RWY 20L | Appendix B-2 to B-2.1 |
3.1.3 Aircraft operators must possess the necessary operational approvals to conduct RNP APCH and BaroVNAV operations from their respective State authorities to carry out these procedures. The on-board performance monitoring and alerting, criteria for specific navigation systems and functional requirement must be in accordance to ICAO Doc 9613.
3.1.4 The pilot must notify ATC of any loss of the RNP APCH capability, together with the proposed course of action. If unable to comply with the requirements of an RNP APCH procedure, pilot must advise ATC as soon as possible. The loss of RNP APCH capability includes any failure or event causing the aircraft to no longer satisfy the RNP APCH requirements.
3.2 Radar Departure SID and Climb Gradient Restrictions
3.2.1 Radar departures designed for Runway 02R and 20L are in accordance to ICAO Doc 8168 Volume II. Details of the procedures can be found in Appendix C of this AIP Supplement as follows:
| Instrument Departure | AIP SUP Reference |
|---|---|
| SID CHA 1C & 1D | Appendix C-1 to C-1.1 |
3.2.2 When there are no reports of vessel movements along the northern shipping channel or when the vessel height is 65m AMSL and below, all aircraft departures on Runway 02R, regardless of on SID or vectors, shall be on a minimum climb gradient of 5% until reaching or passing 2,500ft. Thereafter, the minimum climb gradient shall be 3.3%.
3.2.3 All aircraft departures on Runway 20L, regardless of on SID or vectors, shall be on a minimum climb gradient of 9% until reaching or passing 2,500ft. Thereafter, the minimum climb gradient shall be 3.3%.
3.2.4 The minimum climb gradient restrictions stated above are for the purpose of air traffic management. If the climb gradient restriction cannot be complied with, the pilot-in-command of an aircraft departure shall inform ATC during the time when the aircraft commences taxiing to the holding point for departure. Delays can be expected as coordination is required.
4.1 This AIP Supplement will be cancelled when the contents are incorporated into AIP Singapore.
