Artificial Horizon

Question 1

How is the AH gyro kept in the vertical position

Answer 1

By a pendulous vane unit, providing necessary precessional force if gyro is toppled

Question 2

AH
Does the pitch error indicate a climb, descent or is it correct, and does the bank angle over read, underreads or is it correct when turning through:
1-90°
2-180
3-270
4-360

Answer 2

1-BA under reads, climb
2-BA correct, climb
3-BA over reads, climb
4-BA correct, correct

Question 3

How are bank and pitch indication errors corrected for with an AH

Answer 3

Errors can be compensated for by tilting top or rotor axis slightly forward(erection error) and slightly left(pendulosity error)
