Bartolini and Smart Aviation have fairly similar offers. However, when training for CPL/ME-IR, there is added value in operating from a controlled airport. At the moment, both Lodz and Poznan-Lawica are controlled, but Lodz may be "downgraded" to AFIS in the short term as a cost-saving exercise due to the low level of commercial traffic (IFR procedures would still be there). There is no such project at Poznan - which incidentally also has APP.

P.S: don't ask me how I know; I could tell you, but then I'd have to kill you...
