I was reading this article. The article was about issues that Airbus may face if the UK does a 'Hard Brexit'. At the very end of the Article though, Airbus says
Airbus makes wings for all its jetliners in the UK. The France-based company campaigned against Britain leaving the EU ahead of the UK vote, but has said it would not make abrupt changes to its operations there due to long product cycles.

Can anybody elaborate what the company means by long product cycles?
