Great advice..Also Notrelevant, are you aware that you can make more than one pilot available mate?
You could have a British, German French and American pilot all at the same time (in fact you can have more than one from each nation flying different craft in different squadrons/Jastas etc).and activate the one that takes your fancy at any given time. I often have a couple on the go at once pal.
