Location<br />
1) storage tanks and transfer systems for de-icing/anti-icing fluids; and<br />
2) de-icing crew shelter.<br />
3.15.2 Recommendation.— De-icing/anti-icing facilities should be provided either at aircraft<br />
stands or at specified remote areas along the taxiway leading to the runway meant for takeoff,<br />
provided that adequate drainage arrangements for the collection and safe disposal of<br />
excess de-icing/anti-icing fluids are available to prevent ground water contamination. The<br />
effect of volume of traffic and departure flow rates should also be considered.<br />
Note 1.— One of the primary factors influencing the location of a de-icing/anti-icing<br />
facility is to ensure that the holdover time of the anti-icing treatment is still in effect at<br />
the end of taxiing and when take-off clearance of the treated aeroplane is given.<br />
Note 2.— Remote facilities compensate for changing weather conditions when icing<br />
conditions or blowing snow are expected to occur along the taxi-route taken by the<br />
aeroplane to the runway meant for take-off.<br />

Off-terminal de-icing/anti-icing<br />
8.11 De-icing/anti-icing facilities away from the terminal are recommended when<br />
terminal de-icing/anti-icing facilities (including apron facilities) cause excessive gate<br />
delays and/or taxi times that frequently cause holdover times to be exceeded.<br />
Remote pad de-icing/anti-icing facilities<br />
8.12 Remote de-icing/anti-icing facilities located near departure runway ends or along<br />
taxiways are recommended when taxi times from terminals or off-terminal deicing/anti-icing<br />
locations frequently exceed holdover times. The proper design of<br />
these facilities can also improve flow control by permitting repeat de-icing/anti-icing of<br />
aeroplane critical surfaces without the aeroplane having to return to more distant<br />
treatment sites.<br />
3.15.4 Recommendation.— The remote de-icing/anti-icing facility should be so located as to<br />
provide for an expeditious traffic flow, perhaps with a bypass configuration, and not require<br />
unusual taxiing manoeuvre into and out of the pads.<br />
Note.— The jet blast effects caused by a moving aeroplane on other aeroplanes<br />
receiving the anti-icing treatment or taxiing behind will have to be taken into account<br />
to prevent degradation of the treatment.<br />
3.15.6 Recommendation.— The number of de-icing/anti-icing pads required should be<br />
