Owing to the high concentration of built-up areas, severe airspace limitations and intense low flying aircraft operations, flights by the
following aircraft types are prohibited over the territory of Singapore:
Aircraft principally designed for the purpose of sports or recreation, commonly referred to as home-built, ultralight, microlight, hang-glider and such others, even
though they may have a valid Certificate of Registration or a Certificate of Airworthiness.
Please refer to AIP Singapore page ENR 5.5-1.
