6.4.3.2.3 Recommendation.— Applicants whose uncorrected
distant visual acuity in either eye is worse than 6/60
should be required to provide a full ophthalmic report prior to
initial Medical Assessment and every five years thereafter.
Note 1.— The purpose of the required ophthalmic examination
is (1) to ascertain normal visual performance, and (2) to
identify any significant pathology.
Note 2.— Guidance on the assessment of monocular
applicants under the provisions of 1.2.4.8 is contained in the
Manual of Civil Aviation Medicine (Doc 8984).
6.4.3.3 Applicants who have undergone surgery affecting
the refractive status of the eye shall be assessed as unfit unless
they are free from those sequelae which are likely to interfere
with the safe exercise of their licence and rating privileges.
6.4.3.4 The applicant shall have the ability to read, while
wearing the correcting lenses, if any, required by 6.4.3.2, the
N5 chart or its equivalent at a distance selected by that
applicant in the range of 30 to 50 cm. If this requirement is
met only by the use of near correction, the applicant may be
assessed as fit provided that this near correction is added to the
spectacle correction already prescribed in accordance with
6.4.3.2; if no such correction is prescribed, a pair of spectacles
for near use shall be kept readily available during the exercise
Chapter 6 Annex 1 — Personnel Licensing
6-11 23/11/06
of the privileges of the licence. When near correction is
required, the applicant shall demonstrate that one pair of
spectacles is sufficient to meet both distant and near visual
requirements.
Note 1.— N5 refers to the size of typeface used. For further
details, see the Manual of Civil Aviation Medicine (Doc 8984).
Note 2.— An applicant who needs near correction to meet
the requirement will require “look-over”, bifocal or perhaps
multifocal lenses in order to read the instruments and a chart
or manual held in the hand, and also to make use of distant
vision, through the windscreen, without removing the lenses.
Single-vision near correction (full lenses of one power only,
appropriate for reading) significantly reduces distant visual
acuity and is therefore not acceptable.
Note 3.— Whenever there is a requirement to obtain or
renew correcting lenses, an applicant is expected to advise the
refractionist of the reading distances for the visual flight deck
tasks relevant to the types of aircraft in which the applicant is
likely to function.
6.4.3.4.1 When near correction is required in accordance
with this paragraph, a second pair of near-correction spectacles
shall be kept available for immediate use.
6.4.3.5 The applicant shall be required to have normal
fields of vision.
6.4.3.6 The applicant shall be required to have normal
binocular function.
6.4.3.6.1 Reduced stereopsis, abnormal convergence not
interfering with near vision, and ocular misalignment where
the fusional reserves are sufficient to prevent asthenopia and
diplopia need not be disqualifying.
6.4.4 Hearing requirements
Note.— Attention is called to 2.7.1.3.1 on requirements for
the issue of instrument rating to applicants who hold a private
pilot licence.
6.4.4.1 Applicants who are unable to hear an average
conversational voice in a quiet room, using both ears, at a
distance of 2 m from the examiner and with the back turned to
the examiner, shall be assessed as unfit.
6.4.4.2 When tested by pure-tone audiometry, an applicant
with a hearing loss, in either ear separately, of more than
35 dB at any of the frequencies 500, 1 000 or 2 000 Hz, or
more than 50 dB at 3 000 Hz, shall be assessed as unfit.
6.4.4.3 Recommendation.— An applicant who does not
meet the requirements in 6.4.4.1 or 6.4.4.2 should undergo further
testing in accordance with 6.3.4.1.1.
6.5 Class 3 Medical Assessment
6.5.1 Assessment issue and renewal
6.5.1.1 An applicant for an air traffic controller licence
shall undergo an initial medical examination for the issue of a
Class 3 Medical Assessment.
6.5.1.2 Except where otherwise stated in this section,
holders of air traffic controller licences shall have their Class 3
Medical Assessments renewed at intervals not exceeding those
specified in 1.2.5.2.
6.5.1.3 When the Licensing Authority is satisfied that the
requirements of this section and the general provisions of 6.1
and 6.2 have been met, a Class 3 Medical Assessment shall be
issued to the applicant.
6.5.2 Physical and mental requirements
6.5.2.1 The applicant shall not suffer from any disease or
