Questions for THE ARTIFICIAL HORIZON
Answer the following questions
Test Mode
Training Mode
1. An electrically driven artificial horizon has less errors during the take-off run because
it is less pendulous, has a higher rotor speed and a linear acceleration cut out
the roll cut-out speed is activated
the mercury level switches are more sensitive than the pendulous vanes fitted to air driven types
it is less aperiodic than the air driven types
2. An artificial horizon utilises (i)............ to show (ii)........ in (iii)....... and (iv).............
(i) an earth gyro (ii) latitude (iii) pitch (iv) roll
i) a space gyro (ii) attitude (iii) degrees (iv) minutes
(i) an earth gyro (ii) attitude (iii) pitch (iv) roll
i) an earth gyro (ii) position (iii) latitude (iv) longitude
3. During the take-off run an air driven artificial horizon will usually indicate
a false climbing turn to the left.
a false descending turn to the right.
nose up and incorrect left bank.
increased nose up attitude and right wing low.
4. False nose-up attitude displayed on air driven artificial horizon during the take-off run is caused by
incorrect rotor speed
the lag of the lateral pendulous vanes
the high pendulosity of the rotor
the linear acceleration cut out
5. When an adjustable aircraft datum is fitted to an artificial horizon in light aircraft
it should be set to the central position and left there
it should be set to 15°
it should be checked at regular intervals
it should be rendered inoperative
6. False right wing low attitude shown on an air driven artificial horizon during an acceleration is caused by
the roll cut-out
high rotor speed
the logitudinal pendulous vanes
the lag of the base of the rotor housing
7. Inside an artificial horizon
the rotor axis is kept level by a calibrated spring attached to the outer gimbal ring and the instrument case
there is only one gimbal ring
the inner gimbal ring is pivoted laterally inside the outer gimbal ring and the outer gimbal ring is pivoted longitudinally inside the case
the inner gimbal ring is tied to the vertical by a control system
8. The rotor axis of an electrical horizon is tied to the earth's vertical by
two mercury level switches and two torque motors
the roll cut out
the low centre of gravity of the rotor housing
four pendulous vanes
