(c.) Submit proof of recent reasonable flying experience on
the class of machine for which the license is required,
or, failing such proof, undergo practical tests.

With regard to (b) above the requirements are as follows:—

(1.) PRACTICAL TESTS:—
In each practical test the candidate must be alone in the
flying-machine.

(a.) The tests for altitude and gliding flight and for skill
are the same as those required for a private pilot’s flying-
certificate. Candidates already in possession of the latter
certificate are not required to pass these tests again.

(b.) Test of Endurance.—A cross-country or oversea flight
of at least 200 miles, and the final landing shall be made at
the point of departure. This flight shall be carried out by the
same aircraft within eight hours; and includes two obligatory
landings during which the machine must come to rest, which
shall not be at the point of departure, but which shall be
fixed by the judges. At the time of departure the candidate
shall be informed of his course and furnished with a map.
The judges shall decide if the course has been correctly fol-
lowed.

(2.) TECHNICAL EXAMINATION:—
After satisfactory practical tests have been passed, candi-
dates will submit themselves when summoned to examination
on (a) Flying-machines, (b) engines, (c) navigation.

(a.) Flying-machines: Aeroplanes and Seaplanes.—Theo-
retical abstract knowledge of the resistance of the air in
connection with planes, rudders, elevators, and propellers;
functions of the different parts of the machine and of their
controls. Assembling of aeroplanes, propellers, under-
carriages, rudders, elevators, and their controls. Practical
tests on rigging.

(b.) Engines.—General knowledge of internal-combustion
engines and their various functions, valve-gear, carburation,
ignition, exhaust. Characteristics of aero engines, and a
general idea of their construction, adjustment, and assembling.
Causes of the faulty running of engines. Fuel and oils.
Description of the details of the aero engines used. Adjust-
ments, lubrication, upkeep, dissembling and assembling of the
principal parts; causes of breakdown. Use of throttle and
other controls. Practical tests in running repairs.

(c.) Navigation.—Knowledge of rules for aerial traffic in
the vicinity of aerodromes. Practical knowledge of the special
conditions of aerial traffic. Map-reading, use of compass,
location of position.

Remarks.

The practical tests shall be carried out within a maximum
period of one month. They may be carried out in any order,
and each may be attempted twice. They shall be witnessed
by at least two properly accredited examiners, who will
hand over the official reports to the proper authorities.

The official reports will give full details of the flights,
especially of the landings. The candidates shall furnish,
before each test, proof of identity, which the examiners have
the right to demand.

A barograph shall be carried on all practical tests; and the
graph, signed by the two examiners, shall be attached to their
report.

MEDICAL REQUIREMENTS.

Every applicant, before obtaining a license as pilot of
aircraft engaged in public transport, will present himself for
examination by specially qualified men appointed by or
acting under the authority of the Air Board.

Medical supervision, both for the selection and the main-
tenance of efficiency, shall be based upon the following
requirements of mental and physical fitness:—

(a.) Good family and personal history, with particular
reference to nervous stability. Absence of mental,
moral, or physical defect which will interfere with
flying-efficiency.

(b.) Minimum age for pilots engaged in public transport
shall be nineteen years.

(c.) General surgical examination: The applicant must
neither suffer from any wound, injury, or operation,
nor possess any abnormality, congenital or other-
wise, which will interfere with the efficient and safe
handling of aircraft.

(d.) General medical examination: The applicant must
not suffer from any disease or disability which
renders him liable suddenly to become incompetent
in the management of aircraft. He must possess
heart, lungs, kidneys, and nervous system capable
of withstanding the effects of altitude and also the
effect of prolonged flight.

(e.) Eye-examination: The applicant must possess a
degree of visual acuity compatible with the efficient
performance of his duties. No pilot shall have
more than two dioptrcs of latent hypermetropia;

muscle-balance must be good and commensurate
with the refraction. He must have a good field of
vision in each eye, and must possess normal colour-
perception.

(f.) Ear-examination: The middle ear must be healthy.
The applicant must possess a degree of auditory
acuity compatible with the efficient performance of
his duties.

(g.) The vestibular mechanism must be intact, and neither
unduly hypersensitive nor hyposensitive.

(h.) Nose and throat examination: The applicant must
possess free nasal air-entry on either side, and not
suffer from serious acute or chronic affections of the
upper respiratory tract.

The successful applicant will receive a medical certificate
of acceptance, which must be produced before the license
can be issued.

In order to ensure the maintenance of efficiency every
applicant shall be re-examined periodically, at least every
six months, and the findings attached to his original record.
In case of illness or accident, also, a pilot shall be re-examined
and pronounced fit before resuming aerial duties. The date
and result of each re-examination shall be recorded on the
applicant’s flying-certificate.

No applicant who before the 1st May, 1919, has given proof
of his flying ability shall, so long as he retains such ability,
be necessarily disqualified because he fails to fulfil all of the
above requirements.

Applications for medical examination should be made to
the Secretary, Air Board.

GENERAL.

Holders of licenses may be required from time to time to
undergo further medical examination carried out under the
control of the Air Board.

Licenses shall remain valid for the following periods:
Pilot’s license, six months; other licenses, twelve months;
and shall not be valid unless endorsed by the Air Board at
these intervals.

The fee to be charged in respect of each license issued and
in respect to each such endorsement as aforesaid shall be five
shillings (5s.).

In the event of any applicant being required to undergo
such practical test as is specified in paragraphs above a
further fee of one guinea (£1 1s.) will be charged.

PERSONS COMPETENT TO UNDERTAKE PERIODICAL INSPECTION
AND OVERHAUL AND EXAMINATION BEFORE EACH FLIGHT

    to undergo an examination conducted under the control of
    the Air Board. At this examination the candidate will be

    one years of age; (b) that he has served at least two years
    as a mechanic or engineer on internal-combustion engines,
    or a like period on aircraft construction or maintenance, or a
    period of not under three years on joint aero-engine and
    aircraft construction or maintenance.

13. A candidate may apply to be licensed as a ground
    engineer to overhaul and inspect all flying-machines and
    [or] engines after overhaul and each day before flight; or
    may apply for a license limited to the inspection of any named
    type or types of flying machine or engine, either after over-
    haul and [or] each day before flight.

14. Candidates will be required to submit proof of know-
    ledge—

(a.) For engines: Of the general principles of internal-
combustion engines applied to aircraft, including

cation, and cooling; knowledge of the inspection,
testing, and adjustments necessary for the installa-
tion and functioning of the complete power unit
in the aircraft; and the capacity to supervise or
inspect running repairs and [or] overhaul of particular

(b.) For flying-machines: The general principles of con-
struction, rigging, trueing-up, and adjustment of
