Airmuster,
which us GA jocks have to steer clear of for 30 minutes before and after they depart (so I've heard)...... such crap
Yes that is crap
30mins prior to arrival and departure applies to Jet RPT services. GA are not stopped from operating during these periods, they are however required to submit to passenger screening if departing from the same apron as the RPT service.
From my experience, a lot of these frustrations are not so much the compliance issues but the fact that DOTARS have failed miserably in getting the required information out to the GA industry. On the other hand, pilots perhaps reading ERSA entries and notices clearly written on access gates would go a long way towards avoiding a lot of the grief that occurs especially at regional airports.
