With regard to the paperwork and the pre CPL requirements, is it possible just to fly the required hours, structured as stipulated by the CAA and have the night qualification issued when applying for the CPL? If so, will countersignatures from the instructors in my logbook be sufficient or will the paperwork need signing by them? Only reason I ask this is that I'll have been to two different schools by then to complete my NQ and should have it complete the week before I start my CPL course, at different FTO.
