1) With the basic training course, you will attend 40 hours of lessons. You will have 7 hours of lessons a day. Although, just as a note, I'm not sure what you mean by "follow." I assume you mean that someone taking this course will have seven hours worth of lessons a day (a bit excessive!), but 40 is not divisible by 7. 2) We'd always say "promotional actions" because "promotion" is a noun. We'd also say "aeronautics conference" to refer to a conference about the science of flight. "Aeronautical" means the thing itself pertains to the science of flight. For example, we'd say "The first manned orbital flight was an aeronautical achievement." 3) I'm not quite sure what you mean by "better editing." Here are some sentences that are grammatically correct. I'm not sure which one suits your intentions, however. "We will offer you advice when you complete your curriculum vitae." "We will offer you advice after you have finished editing your curriculum vitae." "We will offer you advice in exchange for completing your curriculum vitae." The last sentence is grammatically correct, although I can think of no plausible circumstance in which it would actually be spoken. 4) I think both of those are grammatically correct. I don't think it would matter much, but you may want to hyphenate in the latter case. ("In the civil-drones sector") 5) It means "they will be." I would say that it means something like "they are to become."
