EFFECT ON LANDING MINIMA OF TEMPORARILY FAILED OR DOWNGRADED GROUND
EQUIPMENT
(a) General
These instructions are intended for both preflight and inflight use. It is, however, not
expected that the pilotincommand would consult such instructions after passing 1 000 ft
above the aerodrome. If failures of ground aids are announced at such a late stage, the
approach could be continued at the pilotincommand’s discretion. If failures are announced
before such a late stage in the approach, their effect on the approach should be
considered as described in Table 6 and, if considered necessary, the approach should be
abandoned.
(b) Conditions applicable to Table 6:
(1) multiple failures of runway/FATO lights other than indicated in Table 6 should not be
acceptable;
(2) deficiencies of approach and runway/FATO lights are treated separately; and
(3) failures other than ILS, MLS affect RVR only and not DH.

AIRCRAFT CATEGORIES
(a) Aircraft categories should be based on the indicated airspeed at threshold (VAT), which is
equal to the stalling speed (VSO) multiplied by 1.3 or where published 1-g (gravity) stall
speed (VS1g) multiplied by 1.23 in the landing configuration at the maximum certified
landing mass. If both VSO and VS1g are available, the higher resulting VAT should be
used.
(b) The aircraft categories specified in the following table should be used.
