                                                                                              (a) unless the turn and slip equipment has a source of power independent of the power operating other gyroscopic instruments; or
                                                                                                (b) a second independent source of attitude information is available that has a source of power independent of the power operating other gyroscopic instruments.

                                                                                                   Note: A gyro-magnetic type of remote indicating compass meets this requirement if it has a primary power supply and alternate power supply.

11.07  IFR flight instruments
 (1) An aeroplane in an operation under the IFR must be fitted with equipment for measuring and displaying the following flight information:
 (a) indicated airspeed;
 (b) pressure altitude;
 (c) magnetic heading;
 (d) time;
 (e) Mach number — but only for an aeroplane with operating limitations expressed in terms of Mach number;
 (f) turn and slip;
 (g) attitude;
 (h) vertical speed;
 (i) stabilised heading;
 (j) outside air temperature;
 (k) whether the supply of power to gyroscopic instruments, if any, is adequate.
 (2) An aeroplane in an operation under the IFR, for which only a single pilot is required under the civil aviation legislation and aeroplane's flight manual, must be fitted with equipment, separate from, and independent of, the corresponding equipment mentioned in subsection (1), for measuring and displaying pressure altitude and attitude.
 (3) An aeroplane in an operation under the IFR, for which 2 pilots are required under the civil aviation legislation or aeroplane's flight manual, must be fitted with equipment, separate from, and independent of, the corresponding equipment mentioned in subsection (1), for measuring and displaying the following flight information:
 (a) indicated airspeed;
 (b) pressure altitude;
 (c) Mach number — but only for an aeroplane with operating limitations expressed in terms of Mach number
 (d) turn and slip;
 (e) attitude;
 (f) vertical speed;
 (g) stabilised heading.
 (4) An aeroplane in an operation under the IFR that has an MTOW of more than 5 700 kg must be fitted with standby attitude equipment that, for the avoidance of doubt, is additional to the attitude equipment required under subsections (1), (2) or (3).
 (5) Despite subsections (1) to (4), for an aeroplane in an operation under the IFR, the equipment for measuring, and displaying, the flight information mentioned in column 1 of an item in Table 11.07(5) must meet the requirements mentioned in column 2 of the same item.
