Section II .—Measures on Arrival.
Article 24.
Aircraft, even when coming from a local area infected by one of
the diseases to which this Chapter applies, may land at any
authorised aerodrome. Nevertheless, each High Contracting Party,
if epidemiological conditions demand such action, has the right to
require aircraft coming from particular local areas to land at
prescribed sanitary or authorised aerodromes, account being taken
of the geographical position of those aerodromes and of the routes
followed by the aircraft, in such a manner as not to hamper aerial
navigation.
The only measures which, if necessary, may be taken at
authorised aerodromes which are not also sanitary aerodromes, are
the medical inspection of crew and passengers and the landing and
isolation of the sick. Passengers and crew r may not move beyond the
limits prescribed by the aerodrome authority except with the permis
sion of the visiting medical officer. This restriction may continue
to be imposed on the aircraft at each landing place until it arrives
at a sanitary aerodrome, where it will be subject to the measures
laid down in this Chapter.
Article 25.
The commander of the aircraft is required, on landing, to place
himself at the disposal of the sanitary authority, to answer all
requests for information affecting public health which are made to
him by the competent service, and to produce the aircraft’s papers
for examination.
Should an aircraft, on entering a territory, land elsewhere than on
a sanitary or authorised aerodrome, the commander of the aircraft
shall, if the aircraft comes from an infected local area or is itself
infected, notify the nearest local authority to this effect, and the latter
shall take such measures as are appropriate to the circumstances,
being guided by the general principles on which the present
Convention is based, and shall, if possible, direct the aircraft to a
sanitary aerodrome. No cargo shall be unloaded and no passenger
or member of the crew shall leave the vicinity of the aircraft without
the permission of the competent sanitary authority.
