Yes. U are right on the Doc7192.
I know in Singapore there is a training on Doc7192 & practical dispatching.incldin 7192Phase 2 syllabus. Mind U,we are not talking abt Jeppesen .
But I don;t know if they train for public as I heard they are approved instructors for Singapore Airlines and airlines running on JAR. Their primary business is actually starting up airlines & Flt Ops Department for Airlines.
My 2cents.
