Staff Profiles

Executive Council

AEF’s work is overseen by an Executive Council that meets every two months. Members come from a range of backgrounds – including business, finance, education and the civil service – and play an active part in our day-to-day activities.


tim johnsonTim Johnson


Tim has worked with the Federation for over twenty years, having joined as Planning Officer in 1989 with a degree majoring in transport planning. He became Director in 1997 following the retirement of the AEF’s founder Moyra Logan.

Tim provides AEF’s representation at the UN International Civil Aviation Organisation (ICAO) as well as on the Department for Transport’s External Advisory Group, and other stakeholder advisory roles associated with the Sustainable Aviation Initiative and the European Commission. On behalf of ICSA (the International Coalition for Sustainable Aviation), Tim plays an active role in ICAO’s Committee on Aviation Environmental Protection including chairing ICAO’s carbon calculator task force, and is currently participating in the Council’s discussions on market-based measure including the MBM Expert Group.

He spent a year working for Defra on aviation issues, a role that left him with some sympathy for the civil servants we try to influence today! He tries to leave all this at the office at the end of each day to spend time with his young family.

Deputy Director

Cait (short for Catrina) joined AEF as Policy and Communications Officer in October 2007 and became Deputy Director in 2009. She has a First Class degree in sociology and an M.A. with Distinction in environmental philosophy, in which her dissertation focussed on the social justice implications of climate change. She now leads AEF’s UK policy work including the emerging UK  airports policy and its compatibility with national climate change strategy and with EU noise and climate commitments.

Cait is a regular conference speaker and has presented at events organised by the Institute for Air Quality Management, the Institute of Civil Engineering, ENDS Europe, and the Westminster Energy Environment and Transport Forum. She has given oral evidence to the Civil Aviation Bill Committee and the London Assembly Transport Committee.

Cait is currently on maternity leave with her second child who was born in early September 2013.


tim thomasTim Thomas

General Aviation Caseworker, Treasurer

Tim has been involved with the AEF for over 30 years, initially through his local parish council at Headcorn in Kent, which he was representing at a local airfield planning appeal. He was elected to the AEF council in the 1990s (when also tackling a further planning appeal at Headcorn) and became AEF treasurer a few years later. Since retiring from BT in 2001, his role at AEF has expanded and he now undertakes part-time general aviation casework and handles membership issues. He also represents AEF at the National Air Traffic Management Committee, where, as the sole environmentalist, he manages to cause some controversy (ask him for details!)

Tim was chairman of his local council for eight years until he decided not to seek reelection in 2012. He continues as chairman of his local history society, which is currently setting up a new village archive. Tim also finds time to chair a local computer club and assist the older generation with their computer problems. At AEF, he is regularly to be found under a desk, fixing our computers. He enjoys the Kent countryside and believes in the value of rural peace and quiet.


nic ferridayNic Ferriday

Air Transport Caseworker

Nic has been an environmentalist ever since leaving university where he obtained a degree in physics. After a career with British Telecom and its previous incarnations he retired early so he could, to use his own words, “do something worthwhile instead of just making money for myself”. Living in West London, he was drawn to the biggest environmental issue in the area and the biggest polluter – Heathrow. He represented Friends of the Earth at the lengthy Heathrow Terminal 5 public inquiry, dealing with aviation policy, air pollution, surface transport, economics, ecology and air pollution. The knowledge and interest gained there led to him becoming a part-time case worker for AEF, dealing with civil aviation.

Nic also campaigns on transport issues for his local Friends of the Earth group, including fighting for better public transport and fewer cars, addressing air pollution, saving open spaces and trying to change planning policies. A particular concern of his, arising from many years of dealing with councils and central government, is the systematic use of spin, bias and misinformation from politicians and from the officials who support them.


WP 000195  2 James Lees

Research and Communications

James started a one year paid internship with AEF in August 2013, having completed a Masters in 2012 in Environmental Change and International Development at the University of Sheffield. Since finishing his Masters he has worked in campaigning and policy roles in Oxfam and Friends of the Earth. He also campaigns on environmental issues in his local area of Watford.

He is looking forward to engaging with local groups on noise and the threat of airport expansion in their local area and supporting AEF’s work to highlight the aviation industry’s responsibility to limit climate change.
