Yes John, F20 or patriot would be acceptable for turbine sign-off, but not optimal! Please understand, this is not an EGO thing! We just want to make sure you are capable of flying turbines. These are dangerous machines with the potential of killing, I want to make sure your skills are at the level needed to take on the added complexities of turbine aircraft. If your skill level is where it needs to be than the waiver process is a piece of cake!
