                                                                                                    (a) be an instantaneous vertical speed indicator (IVSI); or
                                                                                                    (b) meet performance requirements for acceleration sensitivity equivalent to an IVSI.

11.07  IFR flight instruments
 (1) A rotorcraft 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) slip;
 (f) attitude;
 (g) vertical speed;
 (h) stabilised heading;
 (i) standby attitude;
 (j) outside air temperature;
 (k) whether the supply of power to gyroscopic instruments, if any, is adequate.
 (2) A rotorcraft in an operation under the IFR, for which only a single pilot is required under the civil aviation legislation or rotorcraft'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.
 (3) A rotorcraft in an operation under the IFR, for which 2 pilots are required under the civil aviation legislation or rotorcraft'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) slip;
 (d) attitude;
 (e) vertical speed;
 (f) stabilised heading.
 (4) Despite subsections (1) to (3), for a rotorcraft 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(4) must meet the requirements mentioned in column 2 of the same item.
