Regulation 22A
Rules of the Air
Subregulation 1
Subject to paragraphs (2) and (4), the pilot-in-command of a relevant aircraft in flight (including when in the movement area of an aerodrome) must operate the aircraft —
in compliance with the applicable Rules of the Air; and
in the case of a Singapore registered aircraft that is in flight over the high seas, in compliance with the applicable Rules of the Air.
Subregulation 2
However, a breach of any requirement in paragraph (1) is permissible during flight (including when in the movement area of an aerodrome) only if the pilot-in-command of the relevant aircraft is satisfied —
that —
an emergency involving a danger to life or property has arisen in flight;
the extent of the breach of the requirement goes only as far as is necessary to deal with the emergency;
there is no other reasonable means of alleviating, avoiding or assisting with the emergency; and
the degree of danger involved in complying with the requirement is clearly greater than the degree of danger involved in deviating from it; or
that the breach is necessary to comply with the law of any country (including Singapore) within which the aircraft then is, and the extent of the breach of the requirement goes only as far as is necessary to comply with that law.
Subregulation 3
In the event of a breach of any requirement in paragraph (1) because of any circumstances in paragraph (2), the pilot-in-command of the relevant aircraft must, not later than 10 days after the happening of the breach, give written notice about the breach and the circumstances that necessitated it, to the Director-General of Civil Aviation if —
the breach happened anywhere within any Singapore airspace; or
the breach happened elsewhere and involved a Singapore registered aircraft.
