CAA Approves Changes To London City Airport SIDs

Minor technical changes to the London City Airport Standard Instrument Departure (SID) procedures have been approved by the UK Civil Aviation Authority (CAA), and will come into effect on May 7, 2009.

The revised SIDs have been introduced to meet CAA and internationally recognized SID design requirements for Category C aircraft operations performing instrument departures, and will enable greater SID compliance for these particular aircraft.

Aircraft in this category have been operating at London City Airport since the runway was extended some years ago, however the revised procedures will redress some inadequacies in the current SID technical designs. There will be no change to controlled airspace.

Approval to revise existing London City procedures has been given following a rigorous scrutiny of change proposals submitted by the air traffic control service provider NATS earlier this year. The changes were subject to consultation by NATS within the Terminal Control North development consultation, which was undertaken in February 2008 with the aviation community, local government and environmental groups in accordance with the CAA’s Airspace Change Process.

Whilst the NATS TC North proposal is still under development, the CAA nevertheless advised NATS to submit a change proposal in order that improvements to the London City SIDs could be introduced without further delay.

Because of radar vectoring techniques, it is anticipated that there will be minimal differences to flight profiles following the first turn after departure.

Following a thorough safety and environmental analysis by its Directorate of Airspace Policy, the CAA is content that the justification for the changes has been satisfied and that the new designs meet safety requirements. The changes are considered to be necessary and unavoidable and have been introduced to meet CAA regulatory requirements.

Further to this, the CAA has warned that pilots should note that revised SID procedures have been promulgated in the UK AIP AD section with the AIRAC 5 distribution cycle.
