For ab-inito. I don't think so. You need an OCP number for when the PPL application is sent away. Something you don't have as an "independant instructor" unless you are an RTF yourself. You used to be able to set yourself up as one easily, but now you need airside accessable facilities which obviously cost a fair bit when you make the application.
SRG1175 is the form to apply for one.
I am sorry you will have to point me to the post in this thread where we were talking about ab-initio training. And also explain to me how ab-intio relates to the SEP revalidation flight........
