Where can I find the chart/matrix describing what pilot qualifications are required for certain flights to adhere to FAA exemption?

CAPP 70-4, Guide to FAA Exemptions provides the chart describing the qualifications/certification required for certain types of CAP operations and restrictions on reimbursement of costs.

As the Civil Air Patrol conducts a wide variety of aviation mission types while using several different Pilot rating/endorsements, it would be best to utilize the local expertise in your chain of command to help with matching required Pilot qualifications to the CAP aviation mission types where FAA exemptions apply; your Unit, Wing, and Region Stan/Eval Officers are a wealth of knowledge and are ready to assist.
