Interpretation

Trees exceeding 230 ft AMSL, located 0.6–1.0 NM from the RWY 20 threshold between the extended runway centerline and 300 m west of it, penetrate the RWY 02 take-off climb surface and RWY 20 approach surface. RWY 02 TODA is reduced by 152.4 m to 3,931.9 m, and departures require a 5 percent climb gradient until passing 300 ft. RWY 02 and RWY 20 RNP approaches and RWY 20 VOR/DME approaches are not allowed. For other RWY 20 approaches, the decision altitude published in Singapore AIP WSAP AD 2.10 is increased by 200 ft; pilots must not descend below a 3-degree glide path and must land 500 ft beyond the RWY 20 threshold.
