scope:

Purpose of This Order.

This order establishes procedures for issuing special airworthiness certificates in the experimental category or special flight permits to unmanned aircraft systems (UAS) and manned aircraft integrated with UAS technology. For the purposes of this directive, manned aircraft integrated with UAS technology are referred to as optionally piloted aircraft (OPA). For an OPA, the method of controlling the aircraft is optional. This means control may either be through the pilot onboard the aircraft or from a remote station via control link. In either case, the pilot in command always remains onboard the aircraft. Aircraft intended to be flown as either an OPA or UAS will be given the designation "OPA/UAS." The terms "UAS" and "OPA" are further defined in appendix G to this order.

Note: The use of the word "should" throughout this order refers to a recommended practice. The associated activity is not a requirement; therefore, a record of completion is not required.
