DA20-C1 Aeropole's own laminated checklist rXXX. Based on AFM rev 28 and Aeropole Oy's flight school experience in Finland. Approved for use in all Aeropole operations. One copy is to be given to Clients on courses during which the C1 is employed a lot. Two copies to be kept in each aircraft and a couple of copies should be kept at the office as replacement copies (if those in a/c get lost or deteriorate) in addition to copies you need in classrooms/briefing rooms for instructional purposes. NB: Upon publication and order of a new revision, take care to replace all old ones not to have a mixed set of old and new ones around.
