4. the cloud ceiling at the aerodrome is 4,000ft or more for landing on RWY 20 and 3,000ft or more for landing on RWY 02; and

5. the visibility at the aerodrome is 5km or more.

2.5 VESSEL MOVEMENT AFFECTING INSTRUMENT APPROACHES ON RUNWAY 02 AND 20

3.1 INTRODUCTION

1. The Instrument Departure Procedures are only applicable for aircraft with all engines operating. It remains the responsibility of the operator to develop contingency procedures for the individual type of aeroplane and to conduct the necessary examination of obstacles throughout the areas concerned in relation to the certificated performance of the individual aeroplane type. It is also the responsibility of the operator to ensure that contingency procedures comply fully with the aeroplane performance requirements of ICAO Annex 6.

2. The specific routes to be followed are depicted in SID charts AD-2-WSSS-SID-1 to AD-2-WSSS-SID-64. Altitude restrictions at fixes and/or DME specify ATC/airspace requirements.

3. Minimum climb gradient specifies obstacle clearance requirements as well as for the purpose of air traffic management.

4. IfIn the departingevent aircraftthat is unable to comply with the minimum climb gradient required, thecannot pilot-in-commandbe achieved pilots shall inform ATC. DelaysATC canshall behold expecteddepartures if pilots indicate that they are unable to meet the required climb gradient.

3.2 RUNWAY 02L

1. ExceptWhen forthere paragraghare 3.2bno reports of vessel movement along the northern shipping channel or where the reported vessel height is 55m AMSL and below, departingall aircraft departures on Runway 02L, regardless whetherof on SID or vectors, shall be on a minimum climb gradient of 5% until reaching or passing 2500ft2500FT. Thereafter, thereafter the minimum climb gradient shall be 3.3%.

If the minimum climb gradient asrestriction statedcannot inbe paragraphcomplied 3.2awith, the pilot- in-command of an aircraft departure shall inform ATC beforeduring reachingthe time when the aircraft commences taxiing to the holding point for departure. Delays can be expected as coordination is required.

3.3 RUNWAY 02C

ExceptWhen forthere paragraphare 3.3bno reports of vessel movement along the northern shipping channel or where the reported vessel height is 115m AMSL and below, departingall aircraft departures on Runway 02C, regardless whetherof on SID or vectors, shall be on a minimum climb gradient of 5% until reaching or passing 2500ft2500FT.

3.4 RUNWAY 02R

1. ExceptWhen forthere paragraphare 3.4bno reports of vessel movement along the northern shipping channel or where the reported vessel height is 95m AMSL and below, departingall aircraft departures on Runway 02R, regardless whetherof on SID or vectors, shall be on a minimum climb gradient of 5% until reaching or passing 2,500ft. Thereafter, thereafter the minimum climb gradient shall be 3.3%.

3.5 RUNWAYS 20L, 20C AND 20R

3.6 DETERMINATION OF CLIMB GRADIENT BY OPERATORS

1. The most penalising obstacle is taken into account under both all engines operating procedures as well as one engine out procedures; and

2. The required minimum obstacle clearance (MOC) is met under all engines operating procedures.

Note: The calculated climb gradient shall not be lower than the procedure climb gradient for departures.

Note: The distance for departure Runways 02L, 02C and 02R are measured from the DER to the shipping channel north of Changi.

4.1 HOLDING PROCEDURES

Initial approach tracks and holding patterns associated with Singapore Airports are detailed in ENR 3.6 Area Charts. Holding patterns for other airfields are indicated on the applicable approach charts.

1. RWY 02L/02C/02R - SAMKO Holding Area (SHA).
   

2. RWY 20R/20C/20L - NYLON Holding Area (NHA).
   

3. Details of these holding areas and those mentioned in paragraphs 4.1.1.2 and 4.1.1.3 are given in
   ENR 3.6. They are also shown in ENR 3.6 Area Charts.
