AIR NAVIGATION (HONG KONG) ORDER 1995 - SECT 30

Aircraft registered in Hong Kong-Aerodrome operating minima

(1) (a) The operator of every aircraft to which Article 25 of this Order
applies shall establish and include in the operations manual relating to the
aircraft such particulars of aerodrome operating minima as are appropriate to
every aerodrome of intended departure or landing and every alternate
aerodrome: Provided that in relation to any flight wherein it is not
practicable to include such information in the operations manual the operator
of the said aircraft shall, prior to the commencement of the flight, cause to
be furnished, in writing, to the commander of the aircraft such particulars of
the aerodrome operating minima as are appropriate to every aerodrome of
intended departure or landing and every alternate aerodrome and calculated in
accordance with the specified method; and the operator shall cause a copy of
the said particulars to be retained outside the aircraft for a minimum period
of three months.

   (b)  The operator of every such aircraft shall include in the operations
        manual relating to that aircraft such data and instructions as will
        enable the commander of the aircraft to calculate such aerodrome
        operating minima as are appropriate to aerodromes the use of which
        could not reasonably have been foreseen by the operator prior to the
        commencement of the flight.

(2) The aerodrome operating minima specified shall not, in respect of any
aerodrome, be less favourable than any declared in respect of that aerodrome
by the competent authority, unless that authority otherwise permits in
writing.

(3) In establishing aerodrome operating minima for the purposes of this
Article the operator of the aircraft shall take into account the following
matters-

   (a)  the type and performance and handling characteristics of the aircraft
        and any relevant conditions in its certificate of airworthiness; and

   (b)  the composition of its crew; and

   (c)  the physical characteristics of the relevant aerodrome and its
        surroundings; and

   (d)  the dimensions of the runways which may be selected for use; and

   (e)  whether or not there are in use at the relevant aerodrome any aids,
        visual or otherwise to assist aircraft in approach, landing or
        take-off, being aids which the crew of the aircraft are trained and
        equipped to use; the nature of any such aids that are in use; and the
        procedures for approach, landing and take-off which may be adopted
        according to the existence or absence of such aids: and shall
        establish in relation to each runway which may be selected for use
        such aerodrome operating minima as are appropriate to each set of
        circumstances which can reasonably be expected.

(4) An aircraft to which Article 25 of this Order applies shall not commence a
flight at a time when-

   (a)  the cloud ceiling or the runway visual range at the aerodrome of
        departure is less than the relevant minimum specified for take-off; or

   (b)  according to the information available to the commander of the
        aircraft it would not be able, without contravening paragraph (5) of
        this Article, to land at the aerodrome of intended destination at the
        estimated time of arrival there and at any alternate aerodrome at any
        time at which according to a reasonable estimate the aircraft would
        arrive there.

(5) An aircraft to which Article 25 of this Order applies when making a
descent to an aerodrome shall not:-

   (a)  descend below 1000 feet above the height of the aerodrome if the
        relevant runway visual range at the aerodrome is at the time less than
        the specified minimum for landing; or

   (b)  (i) continue an approach to landing at any aerodrome by flying below
        the relevant specified decision height, or

        (ii)   descend below the relevant specified minimum descent height
               unless from that height the specified visual reference of
               landing is established and is maintained.

(6) If, according to the information available, an aircraft would as regards
any flight be required by the Rules of the Air and Air Traffic Control to be
flown in accordance with the Instrument Flight Rules at the aerodrome of
intended landing, the commander of the aircraft shall select prior to take-off
an alternate aerodrome unless no aerodrome suitable for that purpose is
available.

(7) In this Article "specified" in relation to aerodrome operating minima
means such particulars of aerodrome operating minima as have been specified by
the operator in, or are ascertainable by reference to, the operations manual
relating to that aircraft, or furnished in writing to the commander of the
aircraft by the operator pursuant to the proviso to paragraph (1)(a) of this
Article.
