Hi, My name is Darren Sharland and I am a BSc Aircraft Maintenance Engineering student. I am writing a dissertation titled:
"Cabin air quality on large passenger aircraft: Is cabin air clean or contaniminated?"
and to do so I would like your help by completing my short questionnaire. All responses are strictly anonymous so please answer honestly. The questionnaire should take no longer than 5 minutes to complete and can be accessed on the following link:


Thank you for your time and cooperation.
