I got another question what if you have a FAA Multi CPL(No single commercial),have to do recency. Do you have to do all the 15 hrs on the Multi? Can you just do the Day.night and IR checks on the Multi and to the rest on the single?
you can do your 15hrs on SE, but only if are endorsed on that aircraft. as its just command hours. and you should be recent on your multi as well so do all the checks on multi aircraft.
