6.5.3.4 The applicant shall have the ability to read, while
wearing the correcting lenses, if any, required by 6.5.3.2, the
N5 chart or its equivalent at a distance selected by that
applicant in the range of 30 to 50 cm and the ability to read
the N14 chart or its equivalent at a distance of 100 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 6.5.3.2; if no such correction is prescribed, a
pair of spectacles for near use shall be kept readily available
during the exercise 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 and N14 refer 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
multi-focal lenses in order to read radar screens, visual
displays and written or printed material and also to make use
of distant vision, through the windows, without removing the
lenses. Single-vision near correction (full lenses of one power
only, appropriate for reading) may be acceptable for certain
air traffic control duties. However, it should be realized that
single-vision near correction significantly reduces distant
visual acuity.
Note 3.— Whenever there is a requirement to obtain or
renew correcting lenses, an applicant is expected to advise the
refractionist of reading distances for the air traffic control
duties the applicant is likely to perform.
6.5.3.4.1 When near correction is required in accordance
with this paragraph, a second pair of near-correction spectacles
shall be kept available for immediate use.
Chapter 6 Annex 1 — Personnel Licensing
6-15 23/11/06
6.5.3.5 The applicant shall be required to have normal
fields of vision.
6.5.3.6 The applicant shall be required to have normal
binocular function.
6.5.3.6.1 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.
6.5.4 Hearing requirements
6.5.4.1 The applicant, when tested on a pure-tone audiometer
shall not have 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.
6.5.4.1.1 An applicant with a hearing loss greater than the
above may be declared fit provided that the applicant has
normal hearing performance against a background noise that
reproduces or simulates that experienced in a typical air traffic
control working environment.
Note 1.— The frequency composition of the background
noise is defined only to the extent that the frequency range 600
to 4 800 Hz (speech frequency range) is adequately represented.
Note 2.— In the speech material for discrimination testing,
both aviation-relevant phrases and phonetically balanced
words are normally used.
6.5.4.1.2 Alternatively, a practical hearing test conducted
in an air traffic control environment representative of the one
for which the applicant’s licence and ratings are valid may be
used.
