7. AIRPLANE PROCEDURES DURING GANTRY DEICING
WARNING
For personal safety, and to avoid occurrence of incidents caused by
engine suction or blast, engines must be run at idle.
CAUTION
The gantry should be programmed to avoid direct impingement on
engine intakes, windshields and cabin windows, AOA vanes, pitot
heads, static vents, wheels and brakes. If the airplane is deiced using
manual direct spray jets, the above areas should be avoided.
NOTE
Direct spraying is defined as anti-ice fluid jet impact due to spray velocity,
which may cause mechanical damage. If direct spraying occurs to the
engine(s), the pilot should request a wash of both engines on the airplane’s
return to base.
For all deicing/anti-icing procedures, refer to AIRFRAME DEICING,
ANTI-ICING AND INSPECTION earlier in this Supplement.
8. PHASE OF FLIGHT PROCEDURES
NOTE
For all deicing/anti-icing procedures, refer to AIRFRAME DEICING,
ANTI-ICING AND INSPECTION earlier in this Supplement.
A. Push Back
When the parking position is covered with ice or snow, the tow truck may not be capable of
developing normal power to effect a push back due to reduced friction. It is recommended,
therefore, to delay engine start until push back or towing is completed. The flight crew must
be aware that in extreme conditions, the application of the parking brake may not be sufficient
to restrain the forward motion of the airplane, with the engines at idle thrust.

8. PHASE OF FLIGHT PROCEDURES (CONT'D)
B. Engine Start
(1) Normal engine start procedures .................. Accomplish • Refer to Chapter 4;
NORMAL PROCEDURES –
ENGINE STARTING.
• It may be necessary to use
ground heating to warm the
starter valve, fuel control
unit and ignition system, if
the engine fails to start
normally.
• If ground heating was used
to remove ice build-up from
the fan, start the engine
immediately to prevent
refreezing.
(2) Engine Instruments .......................................... Observe for normal operation
• During cold weather starts,
initial oil pressure response
may be slow, and is not
unusual. The oil pressure
indication may then indicate
higher than the normal
range, and should
progressively reduce to
normal readings as the
engine achieves normal
operating temperatures
(115 psid at idle, 10 minutes
maximum).
NOTE
No oil pressure indication by the time idle RPM is achieved requires an
immediate shutdown.
C. After Engine Start
(1) Electrical power ............................................ Transfer to
generators Expect generators to be slow
in producing steady power due
to cold oil in the IDGs. Five
minutes may be required for
the IDGs to stabilize
sufficiently.
(2) ANTI-ICE, WING and COWL ...................... As required

WARNING
When Type II, Type III or Type IV anti-icing fluids have been applied,
use of wing anti-ice heat prior to take-off can cook the fluid onto the
leading edges of the wing, creating contamination.
NOTE
1. If snow, ice or frost is detected in any amount on the wings and tail
surfaces of the airplane, then the airplane must be treated with deicing
fluids prior to take-off.
2. The following procedure should not be used if the airplane has been
treated with deicing fluids:
Prior to the first flight of the day, whenever the OAT is 5°C (41°F) or
below, and it is suspected that the overnight conditions have been
