## Minor in Aero/Astro
A student who wishes to obtain a Ph.D. minor in Aero/Astro should consult with the Aero/Astro Student Services Office for designation of a minor advisor. A Ph.D. minor in Aeronautics and Astronautics may be obtained by completing 20 units of graded, graduate-level courses in the Aero/Astro Department, following a program (and performance) approved by the department’s Director of Graduate Studies. Seminars and independent study (research) units do not count toward the required 20 units. A minimum grade point average (GPA) of 3.0 on these courses is required to fulfill the Ph.D. minor. The student’s Ph.D. Reading Committee and University Oral Committee must each include at least one faculty member from Aero/Astro.
