CFII add-on
All
a simple question, regarding ---
I already have a CFII for helicopters and a CFI for single engine fixed wing and rated for instrument airplane. Want to add a CFII for the single engine airplane, and want to confirm what written test i need to take. Have been told thru CFIs,FSDOs it is the FII test --Flight Instructor Instrument Airplane-- test code is FII?
does this make sense ?
