*These limitations refer to use of the DR400 under the “Utility” category, in simple terms no rear seat loading and a mass below 910kg, ie; when towing. Above 910kg and with rear seat(s) occupied, the aircraft is operating under the “Normal” category which limits the aircraft load factor to +3.8g and -1.9g.  Typical towing mass is 700-750kg. If you plan to fly the aircraft with rear seat passengers and/or auxiliary fuel, please consult the Aircraft Flight Manual for specific limitations. Note: Load factor reduces to +2g and 0g when flaps extended in both categories. The DR300 is approved only for use in the “Normal” category hence the lower load factor range.
