Benefits of steeper approach landings at Heathrow

T Henderson made this Freedom of Information request to Civil Aviation Authority

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was refused by Civil Aviation Authority.

Dear Civil Aviation Authority,

Further to my request F0001432 ( A380 : Steep approach landing), I note that the released email chain included mention of an action for the CAA to do work on "the potential benefits of steeper approaches and displaced landing thresholds at Heathrow."

Under the Environmental Information Regulations, please can you supply information on the CAA work and its outcomes to show the benefits of steeper approaches and landing thresholds at Heathrow.

I am aware of the case study "Steeper approaches vs displaced landings" on page 32 of the CAA Insight note "Aviation Policy for the Environment"

http://www.caa.co.uk/docs/589/CAA_Insigh...

but this only appears to report on the effects of displaced landings.

Yours faithfully,

T Henderson

Dear Civil Aviation Authority,

Please pass this on to the person who conducts Freedom of Information reviews.

I am writing to request an internal review of Civil Aviation Authority's handling of my FOI request 'Benefits of steeper approach landings at Heathrow'.

I note that you state that you hold an "internal document that falls within the scope of the request" and that it is "a complete and finished document" exploring ideas and opportunities in an unconstrained way.

I appreciate that further work may be required on other aspects of the environmental and technical feasibility of steeper approaches to permit, in due course, a thorough analysis, complete a "workstream" and make a policy decision, but I was not seeking this - only the document referred to as the output of the minuted action and which you describe as complete.

Accordingly I seek a review of the decision to exempt it on the basis that it is an incomplete document.

I would add that the public interest case for release is strengthened by the very recent and current DfT consultation on the night flights regime for the London airports. Section 5.16 and question 15 deal with the topic and seek "potentially significant information" on steeper approaches. Thus I would suggest that the release would "allow the public to be informed and involved in such decisions" as the consultation is seeking to do.

A full history of my FOI request and all correspondence is available on the Internet at this address:

Dear Mr Henderson,

Thank you for your patience in this matter. Having now consulted with the relevant CAA department, I regret that the piece of work concerned is not tied to a specific publication cycle; consequently, the CAA is unable to furnish you with an estimated completion date.

Yours sincerely,

FOI Requests, Civil Aviation Authority

Dear Mr Henderson

 

As required by the Information Commissioner’s decision notice of 9 October
2013, I am writing in relation to your request for information of 12
December 2012 regarding work being carried out by the Civil Aviation
Authority (CAA) on the benefits of steeper approaches at Heathrow.

 

As we explained to the Commissioner, it is difficult to put precise
timescales on this activity, since we are dependent on external factors
and support from the aviation industry. As an example, a UK airline has
agreed to assist us by providing time in a flight simulator which we hoped
would take place earlier this year. However, due to changes in the
airline’s own requirements for the use of their simulators this had to be
postponed and is currently scheduled to take place in January 2014.

 

Currently, we would expect within 6 to 9 months to be in a position to
determine our policy position and share it with a wider audience, as we
have done in other circumstances, e.g. the CAA [1]Insight Note on Aviation
and the Environment, published in December 2011.  As noted above, this
remains dependent on external factors.

 

Yours sincerely
