A CFI can instruct in an experimental when:
- he is instructing the Owner of the Experimental Aircaft, or
- He has a Letter of Deviation Authority (LODA) from the FAA.
Recent guidance from FAA says that an LODA for Flight training may include:
- Initial flight training for the operation of specific make and model of experimental aircraft.
- Recurrent flight training for the operation of a specific make and model of experimental aircraft.
- Primary flight training for the operation of
ultralight vehicles only when conducted in low mass, high drag vehicles
with an empty weight less than 500 pounds and a maximum speed in level
flight with maximum continuous power (VH) less than 87 knots calibrated
airspeed (CAS).
- Jet unusual attitude and upset training.
- Instrument competency training for specific make and model of experimental aircraft.
- Training for a flight review in a specific make and model of experimental aircraft.
- Formation training for specific make and model of experimental aircraft.
- Other specific training approved by the General Aviation and Commercial Division, AFS-800.
