- A maximum seating capacity of no more than two persons, including the pilot.
- A single, non-turbine engine fitted with a propeller.

The Multi-Disciplinary Measure (MDM) group MDM.032 is working on proposals to reduce the regulatory burden on these recreational aircraft. These changes to the regulations, when in place, will replace the interim measures set out above.
