                1.2.6.3     Equipment requirements for VFR Night flights


                Aircraft used for VFR night flying must have gyros to ensure, in the absence of

                a  true  horizon,  that  the  wings  can  be  kept  level  using  an  artificial  horizon.

                There must be a course gyro and a turn indicator.

                The system must be fail-safe, so it’s not enough for all of them to be vacuum-

                driven because if this system fails, we’re in trouble.


                Redundancy is achieved by having at least one gyro, typically the turn indicator,

                powered by an alternate system. This alternative system is usually electricity.

                To  ensure  this  system,  there  must  be  a  mechanism  showing  power  supply

                failure, such as a Low Voltage Warning.

                There must be a navigation system that is connected to the aircraft’s electrical

                system and permanently installed.




                With the installation of these items and approval from the Danish Transport

                Agency, the aircraft manual will show that the aircraft is approved for VFR night
                operations.
