My two cents....
Surely, if a student has been signed off by an unrestr.FI for first solo/x country, then he has met and proved all the relevant standards for any solo or solo x country. If a restr FI subsequently wants to send the stude solo, and provided club
recency and weather conditions permit, then this should be fine even without flying with the student. A thorough brief and scenario discussion, a check on his student records and if possible, a chat with the previous instructor, should suffice. The student is either capable for solo/x country or not at his first solo/x country check. I believe this would be satisfactory in a court.
With regards first solo:As CFI, I would ask my restr.FI to fly with their student until THEY would have sent them first solo, before i fly with the student. This way the law is met and the new FI has an assessment as to their decision making on first solo's. This will hopefully improve their confidence for when they become unrestricted.
My views, hope they help!
