Under the constitution of the ATC, each squadron must be overseen by a Civilian Welfare Committee of no fewer than five persons. 

158 Squadron committee meets approximately once every two months for a couple of hours one evening, usually at the Cadet Centre in Braintree. Discussion and subsequent actions are primarily focused around expenditure and fund-raising for the Squadron.

The main purpose of the committee is to ensure local independent non-RAF control of the squadron. Much time is devoted to fund-raising for the Squadron which as a part of the ATC is a registered charity.
