(5) Aircraft De-icing Requirements.
(aa) Annually, Heathrow publishes an Aircraft De-icing Plan (HADIP). All airline operators should ensure that
they have read and understood this document. A copy of the plan can be downloaded from
Heathrow: Welcome to Heathrow Airport
airside.
(bb) During periods of high demand for de-icing, Heathrow activates the A-CDM ‘Winter Module’ which includes
aircraft de-icing rig allocation capability.
(cc) In order to request de-icing, pilots should follow their company’s standard procedure. In accordance with
Heathrow’s de-icing plan, operators will enter the requirement for de-icing into A-CDM, which will ensure that deicing
resources are allocated appropriately. If the aircraft is to be de-iced remotely, operating companies will pass
this information to pilots prior to push. Remote de-icing facility locations are shown on chart AD 2-EGLL-2-8.
(dd) When doors are closed and ready to commence de-icing on gate, pilots must call Heathrow Delivery stating
“Ready for de-icing”. This call must be made at +/- 5 minutes from TOBT.
(ee) Once de-icing on the gate is complete, pilots should call Heathrow Delivery again, stating 'De-icing
complete, ready to push and start'.
(ff) Pilots who have been allocated a remote de-icing area should contact Heathrow Delivery, stating 'Ready to
push and start for remote de-icing'.
