RE: Software Code for Air Transport Models

Dear Mr Todd,

Thank you for your request for information relating to the Department's aviation forecasting models, received on 23^rd February 2010. The DfT reference for your request is E0006237. As the subject of your request falls within the definition of 'environmental information' as set out in Regulation 2 of the Environmental Information Regulations 2004 ("the EIRs"), we have handled your request in accordance with that regime.

I am writing to advise you that the time limit for responding to your request needs to be extended.

The Regulations allow us 20 working days to respond to your request. However, it is occasionally necessary to extend the 20-working-day time limit for issuing a response. In this case, I regret that we must extend the time limit for responding by 20 working days because of the complex and voluminous nature of the request.

We now hope to let you have a response by 22^nd April 2010. We will make every effort to meet that new deadline, however if there is any further delay I will keep you informed.

If you are unhappy with the way the Department has handled your request or with the decisions made in relation to your request you may complain within 40 working days of the date of this letter by writing to the Department's Information Rights Unit at:

Zone D/04

Annex A

Your right to complain to DfT and the Information Commissioner

You have the right to complain within two calendar months of the date of this letter about the way in which your request for information was handled and/or about the decision not to disclose all or part of the information requested. In addition a complaint can be made that DfT has not complied with its FOI publication scheme.

Your complaint will be acknowledged and you will be advised of a target date by which to expect a response. Initially your complaint will be re-considered by the official who dealt with your request for information. If, after careful consideration, that official decides that his/her decision was correct, your complaint will automatically be referred to a senior independent official who will conduct a further review. You will be advised of the outcome of your complaint and if a decision is taken to disclose information originally withheld this will be done as soon as possible.

If you are not content with the outcome of the internal review, you have the right to apply directly to the Information Commissioner for a decision. The Information Commissioner can be contacted at:
