12.40.2 | Outline the basic principle of operation of the vacuum system. |
12.40.4 | State the likely effects of reduced or nil suction in the vacuum system . |
12.40.6 | Describe the gyroscopic properties of: (a) rigidity; (b) precession. |
12.40.8 | With respect to the turn indicator/coordinator: (a) explain the basic principle of a rate gyroscope; (b) differentiate between the different indications of the turn indicator and turn coordinator; (c) state the function, indication and correct use of the coordination (balance) ball. |
12.40.10 | With respect to the attitude indicator (or artificial horizon) explain: (a) the basic principle of operation (earth gyroscope); (b) how pitch attitude and bank angle are displayed; (c) the pilot checks for serviceability. |
12.40.12 | With respect to the heading indicator (or DGI), explain the: (a) advantages of a gyroscopic heading indicator (versus a compass); (b) need for, and method of synchronising the HI with the compass; (c) pilot checks for serviceability. |
12.40.14 | Briefly explain the errors likely to occur if: (a) the gyro rotor rpm is low; (b) there is an indication of a power failure on an electrically-driven gyro. |
12.40.16 | Describe the indications of toppling. |
