Dear Department for Transport,
The Statement of Need for the Heathrow Airport proposal for an airspace change to the CPT Departure SID 09L/R at

(linked from the airspace portal page at )

includes the statements

"3. In 2009, this manual interaction by air traffic controllers was standardised and implemented as a trial procedure in the live environment. The procedure remains in operation and published in local air traffic control procedures as a trial."


"Since 2009, Heathrow Airport Limited have, on two occasions, tried to formalise a new CPT SID procedure, however on both occasions, and for differing reasons, firstly the CAA and then DfT, delayed the Airspace Change Proposal from progressing."

Under the Environmental Information Regulations, please could you provide information held by DfT on the attempts to formalise new CPT SID procedures and on the reasons why they were delayed from progressing.

Yours faithfully,

T J Henderson
