6.4.2.25 The applicant shall not possess any abnormality
or disease of the ear or related structures which is likely to
interfere with the safe exercise of the applicant’s licence and
rating privileges.
6.4.2.26 There shall be:
a) no disturbance of the vestibular function;
b) no significant dysfunction of the Eustachian tubes; and
c) no unhealed perforation of the tympanic membranes.
6.4.2.26.1 A single dry perforation of the tympanic
membrane need not render the applicant unfit.
Note.—Guidance on testing of the vestibular function is contained
in the Manual of Civil Aviation Medicine (Doc 8984).
6.4.2.27 There shall be:
a) no nasal obstruction; and
b) no malformation nor any disease of the buccal cavity or
upper respiratory tract;
which is likely to interfere with the safe exercise of the applicant’s
licence and rating privileges.
6.4.2.28 Applicants with stuttering and other speech
defects sufficiently severe to cause impairment of speech
communication shall be assessed as unfit.
6.4.3 Visual requirements
The medical examination shall be based on the following
requirements.
6.4.3.1 The function of the eyes and their adnexa shall be
normal. There shall be no active pathological condition, acute
or chronic, nor any sequelae of surgery or trauma of the eyes
or their adnexa likely to reduce proper visual function to an
extent that would interfere with the safe exercise of the
applicant’s licence and rating privileges.
6.4.3.2 Distant visual acuity with or without correction
shall be 6/12 or better in each eye separately, and binocular
visual acuity shall be 6/9 or better. No limits apply to uncorrected
visual acuity. Where this standard of visual acuity can
be obtained only with correcting lenses, the applicant may be
assessed as fit provided that:
a) such correcting lenses are worn during the exercise of
the privileges of the licence or rating applied for or held;
and
b) in addition, a pair of suitable correcting spectacles is kept
readily available during the exercise of the privileges of
the applicant’s licence.
Note.— An applicant accepted as meeting these provisions
is deemed to continue to do so unless there is reason to suspect
otherwise, in which case an ophthalmic report is required at
the discretion of the Licensing Authority. Both uncorrected and
corrected visual acuity are normally measured and recorded at
each re-examination. Conditions which indicate a need to
obtain an ophthalmic report include: a substantial decrease in
the uncorrected visual acuity, any decrease in best corrected
visual acuity, and the occurrence of eye disease, eye injury or
eye surgery.
6.4.3.2.1 Applicants may use contact lenses to meet this
requirement provided that:
a) the lenses are monofocal and non-tinted;
b) the lenses are well tolerated; and
c) a pair of suitable correcting spectacles is kept readily
available during the exercise of the licence privileges.
Note.— Applicants who use contact lenses may not need
to have their uncorrected visual acuity measured at each
re-examination provided the history of their contact lens
prescription is known.
6.4.3.2.2 Applicants with a large refractive error shall use
contact lenses or high-index spectacle lenses.
Note.— If spectacles are used, high-index lenses are needed
to minimize peripheral field distortion.
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
