Forgive me for my ignorance, but all flights leaving BHX on published SIDS & STARs do so within the confines of controlled airspace and positive radar control. Even Coventry departures join controlled airspace at 1500 feet or am I missing something? Do I need to get my Air Law text books out again?
There is a BRECON departure out of Birmingham/Coventry which takes aircraft outside of CAS. Usually noise abatement procedures after departure then a turn towards BRECON climbing FL80 initially. Aircraft are then advised to contact London Mil. Also, Flybe aircraft tend to go outside CAS when positioning aircraft between Birmingham & Exeter.
Not sure of the 1500ft being the base of CAS, isn't it FL44 around that area for Coventry arr/deps?
