1. LANDING GEAR, WHEELS AND BRAKES (CONT'D)
D. Procedures for Operating from Wet, Snow Covered or Slush Covered Surfaces
When operating from wet, snow covered or slush covered runways or taxiways, or following
overnight parking in known icing conditions, the following steps are applicable in order to
prevent freezing of the wheel brakes:
1. During taxi, perform the following number of firm brake applications from 25 knots to
10 knots. Perform the prescribed number of brake applications during the last
mile/kilometer of taxi prior to and not including the final stop or snub before take-off.
Do not drag the brakes.
AIRPLANE WEIGHT NUMBER OF BRAKE APPLICATIONS
Greater than 42,000 lb 5
36,000 to 42,000 lb 6
Less than 36,000 lb 7
NOTE
1. Use of symmetric braking is recommended to ensure uniform
brake heating.
2. Warming of the brakes will preclude the chance of water
saturated brakes freezing at altitude and being locked for
landing touchdown.
2. During take-off, unless weather conditions or performance requirements prohibit,
delay retraction of the landing gear until excess water, snow or slush is thrown off by
wheel rotation and/or slip stream force.
3. When landing, carry out a positive landing to ensure initial wheel spin-up and
breakout of frozen brakes, if icing accumulation on the wheels and brakes is
suspected.
4. During the landing roll and subsequent taxi, use the brakes to prevent progressive
build-up of ice on the wheels and brakes.
Following take-off or landing on water, snow or slush covered runways and taxiways, tires
should be inspected for flat-spotting prior to the next flight.

WARNING
When the OAT is 5°C (41°F) or below use deicing/anti-icing
treatment before take-off.
When the OAT is 5°C (41°F) or below the wing anti-ice
system must be selected ON for take-off, just prior to thrust
increase for take-off.
NOTE
1. When Type II, III or IV anti-icing fluids have been applied,
the wing anti-ice system must only be selected on, if
required, just prior to thrust increase for take-off.
2. The engine cowl anti-ice system must be on when the OAT
is 10°C (50°F) or below, and visible moisture in any form is
present (such as fog with visibility of one mile or less, rain,
snow, sleet and ice crystals).
3. The engine cowl anti-ice system must also be on when the
OAT is 10°C (50°F) or below when operating on runways,
ramps, or taxiways where surface snow, ice, standing water
or slush is present.
4. Icing conditions exist in flight at a TAT of 10°C (50°F) or
below, and visible moisture in any form is encountered
(such as clouds, rain, snow, sleet or ice crystals), except
when the SAT is –40°C (–40°F) or below.
E. Cooling of Wheels, Brakes and Tires
Brake cooling times, derived from Chapter 6; PERFORMANCE – TURN-AROUND TIME,
must be observed between a landing or a low energy rejected take-off (RTO) and a
subsequent take-off.
F. Nose Wheel Steering – On Ground
CAUTION
Always make sure that the steering is within the nominal operating
range of ±55° before re-cycling the arming switch.
