4. Altimeter Operation
When the aircraft climbs or descends, changing pressure within the altimeter case expands or contracts the aneroid barometer.
A decrease in pressure causes the altimeter to indicate an increase in altitude, and an increase in pressure causes the altimeter to indicate a decrease in altitude.

FAA – Pilot’s Handbook of Aeronautical Knowledge

23. Today’s Mission Requirements
Identify in writing how to interpret and operate flight instruments.
Describe the pilot’s ability to recognize errors and malfunctions with flight instruments.
Describe the pitot-static system and associated instruments.
Describe the vacuum system and related instruments.

EQ:
Describe the importance of Aeronautical Knowledge for the student pilot learning to fly.

24. Gyroscopic Flight Instruments
Several flight instruments utilize the properties of a gyroscope for their operation.
The most common instruments containing gyroscopes are the turn coordinator, heading indicator, and the attitude indicator.

25. Gyroscopic Flight Instruments Sources of Power
Gyros are vacuum, pressure, or electrically operated.
Most aircraft have at least two sources of power to ensure at least one source of bank information is available if one power source fails.

26. Gyroscopic Flight Instruments Sources of Power
The vacuum or pressure system spins the gyro by drawing a stream of air against the rotor vanes to spin the rotor at high speed, much like the operation of a waterwheel or turbine.

27. Gyroscopic Flight Instruments Sources of Power
Pressure required for instrument operation varies, but is usually between 4.5 "Hg and 5.5 "Hg.
One source of vacuum for the gyros is a vane-type engine-driven pump that is mounted on the accessory case of the engine.

28. Gyroscopic Flight Instruments Sources of Power
A typical vacuum system consists of an engine-driven vacuum pump, relief valve, air filter, gauge, and tubing necessary to complete the connections.

29. Gyroscopic Flight Instruments Sources of Power
Air is drawn into the vacuum system by the engine-driven vacuum pump.
It first goes through a filter, which prevents foreign matter from entering the vacuum or pressure system.

30. Gyroscopic Flight Instruments Sources of Power
The air then moves through the attitude and heading indicators, where it causes the gyros to spin.
A relief valve prevents the vacuum pressure, or suction, from exceeding prescribed limits.

31. Gyroscopic Flight Instruments Sources of Power
It is important to monitor vacuum pressure during flight, because the attitude and heading indicators may not provide reliable information when suction pressure is low.

32. Gyroscopic Flight Instruments Sources of Power
When the vacuum pressure drops below the normal operating range, the gyroscopic instruments may become unstable and inaccurate.

33. Turn Indicators
Aircraft use two types of turn indicators: turn-and-slip indicator and turn coordinator.
The turn-and-slip indicator shows only the rate of turn in degrees per second.

34. Turn Indicators
The turn coordinator can initially show roll rate and it indicates rate of turn.
Both instruments indicate turn direction and quality (coordination), and also serve as a backup source of bank information in the event an attitude indicator fails.

35. Turn Indicators
Coordination is achieved by referring to the inclinometer, which consists of a liquid-filled curved tube with a ball inside.

36. Turn-and-Slip Indicator
The turn-and-slip indicator uses a pointer, called the turn needle, to show the direction and rate of turn.

37. Turn Coordinator
The turn coordinator can be used to establish and maintain a standard-rate turn by aligning the wing of the miniature aircraft with the turn index.

38. Turn Coordinator
Two marks on each side (left and right) of the face of the instrument.
The first mark
a wings level zero rate of turn.
The second mark
indicate a standard rate of turn.

39. Turn Coordinator
A standard-rate turn is defined as a turn rate of 3° per second.
The turn coordinator indicates only the rate and direction of turn; it does not display a specific angle of bank.

40. Inclinometer The inclinometer is used to depict aircraft yaw.
Coordinated flight is maintained by keeping the ball centered.
If the ball is not centered, it can be centered by using the rudder.

41. Inclinometer
To center the ball, apply rudder pressure on the side to which the ball is deflected.
Use the simple rule, “step on the ball,” to remember which rudder pedal to press.

42. Inclinometer Instrument Check
During the preflight, check to see that the inclinometer is full of fluid and has no air bubbles.
The ball should also be resting at its lowest point.
When taxiing, the turn coordinator should indicate a turn in the correct direction while the ball moves opposite the direction of the turn.

43. Attitude Indicator
The attitude indicator, with its miniature aircraft and horizon bar, displays a picture of the attitude of the aircraft.
The relationship of the miniature aircraft to the horizon bar is the same as the relationship of the real aircraft to the actual horizon.

44. Attitude Indicator
The instrument gives an instantaneous indication of even the smallest changes in attitude.
The horizon bar represents the true horizon.

45. Attitude Indicator
The attitude indicator is reliable and the most realistic flight instrument on the instrument panel.

46. Heading Indicator
The heading indicator is fundamentally a mechanical instrument designed to facilitate the use of the magnetic compass.
Errors in the magnetic compass are numerous, making straight flight and precision turns to headings difficult to accomplish, particularly in turbulent air.

47. Heading Indicator
Because of precession caused by friction, the heading indicator creeps or drifts from a heading to which it is set.

48. Heading Indicator
Another error in the heading indicator is caused by the fact that the gyro is oriented in space, and the Earth rotates in space at a rate of 15° in 1 hour.
The heading indicator may indicate as much as 15° error per every hour of operation.

49. Heading Indicator Instrument Check
As the gyro spools up, make sure there are no abnormal sounds.
While taxiing, the instrument should indicate turns in the correct direction, and precession should not be abnormal.
