I have a new student that wants to get his initial private pilot certificate in a multi engine. He wants to fly to airports to airports in Florida for business purposes with me in the plane, have me wait for 2-3 hours at the FBO while he conducts his business and then fly back in the twin. The flight training will be done before or during the trip.

Like most, if not all flight schools, our flight school and insurance company will not allow a non-rated pilot to solo in the twin. So my question is - can he solo as the "solo manipulator of the airplane" for his first solo in the twin? I'm thinking he can't because...

"§ 61.87 Solo requirements for student pilots.
(a) General. A student pilot may not operate an aircraft in solo flight unless
that student has met the requirements of this section. The term ‘‘solo flight’’ as used in this subpart means that flight time during which a student pilot is the sole occupant of the aircraft or that flight time during which the student performs the duties of a pilot in command of a gas balloon or an airship requiring more than one pilot flight crewmember."

We also have a glass cockpit G1000 182T, but he can't solo in that plane without a private pilot certificate. These are the only 2 aircraft that he wants to fly in since they have a higher cruising speed compared to the 172s/152s.

Any ideas? Should I keep him in the C172 for training and do the business trips in the twin with some training? I'm not sure if he can keep up with 2 different training paths at the same time.
