1. What air pressure does the air speed indicator use?
Both pitot (RAM) and static
2. How does the air speed indicator work?
It determines the airspeed through the air by comparing the RAM (Pitot) pressue vs. the static pressure.

The greater the difference, the greater the speed.
3. Performance airspeeds are
always the same indicated airspeed regardless of the altitude.
4. What are the types of airspeed?

It is the reading from the indicator.

It does not reflect variation in air density.

It is uncorrected for position.
6. Define Calibrated airspeed, (CAS)
It is the indicated airspee corrected for position and instuments using the POH chart.
7. Define True airspeed, (TAS)
It is the true speed through air.

It is Calibrated airspeed corrected for altitude and temperature.
8. The altimeter works by...
sensing pressure changes. It displays the altitude in feet.
9. Describe the 3 hands of an altimeter

10. The altimeter is affected by ...
air pressure.
11. The ________ has to be adjust on the altimeter as you from from one region to another.
barameter
12. On an altimeter 0.01mm of Hg =
10 feet of change in altitude.
13. The altimeter measures
the vertical elevation above a reference point.

Surface o the earth = mean sea level

• Calibrated
• Absolute
15. Define Indicated Altitude
altitude measured by the altimeter
16. Define Pressure Altitude
Height above the standard datum plane when the barameter is set to 29.92.

Standard datum plane = the theoretical pressure line where atmospheric pressure = 29.92.
17. Define Density Altitude
Density altitude is pressure altitude corrected for nonstandard temperature.

Density altitude increases as abient temperature increases.

Standard temp. = 15oC (59oF)
18. Define Calibrated Altitude
Calibrated ALtitude is Indicated Altitue corrected for instrument error.
19. Define True Altitude
Actual height of an object above mean see level.

FAA: True Altitude is the actual vertical distance bove mean sea level and is = to pressure altitude when standard atmospheric conditions exist.
20. True altitude is =___________ under standard atmospheric conditions.
Pressure Altitude and Indicated altitude
21. True Altitude =____________ when the altimeter is set to the local pressure setting.
fiels elevation
22. Define Absolute Altitude
Absolute altitude is the vertical distance above the surfce.

also called above ground level
23. Altimeter memory aids
- fly from high to low without resetting the altimeter the altimeter will indicate higher than actual(true) altitude.

- fly low to high the altimeter will show lower than the actual (true) altitude.
24. A 1 inch change in the altimeter setting =
1000 feet of indicated altitude change in the same direction.
25. Remember:

When flying from high to low, look out below.
26. Temperature effects on altitude
- When temperature is higher then standard, pressure levels are raised.  True altitude is higher then indicated.

-When temperatures are colder then stndard, pressure levels are lowered.  Tre altitude is lower the indicated altitude.
27. How doess the vertical speed indicator work?
The vertical speed indicator uses static pressure to display a rate of climb/or descent in feet/minute.

It measures how fast the ambient air pressure is increasing or decreasing.
28. What flight instument is affected if the pitot tube is blocked?
airspeed indicator
29. What instruments are affected if the static port is clogged?
• air speed indicator
• altimeter
• vertical speed indicator
30. What are the gyroscopic instruments?
• turn coordinator
• attitude indicator
• heding indicator
31. What is (are) the magnetic flight instrument(s)
Magnetic compass
32. Engine temperature may be reduced by
• Reducing the rate of climb
• enriching the fuel mixture
• Increasing the airspeed
• Reducing power
33. Pitot Static instruments use air pressure differences to measure ....
speed and altitude
34. Pitot  pressure is also called...
Impact or ram pressure

It provides an indication of turn direction & quality.

It uses  ball in a tube, inclinometer

FAA: shows aircraft yaw & roll movements
43. A standrd rate of turn =
• 3o / second
• complete a 360o urn in 2 minutes
44. Turn slip
The rate of speed is too slow for the angle of bank.  The ball moves to the inside of the turn.

The rate of speed is too great for the ngle of bnk.  The ball moves to the outside of the turn.
46. Function of the Attitude Indicator
FAA: As the plane banks the reltionship between the miniature plane and the horizon bar shows the direction of the turn.

It senses the roll & pitch (which is up & down of planes nose)
47. The 4 forces of flight
• Lift
• Weight
• Thrust
• Drag
48. Relationship of Forces of flight per the Faa
These forces are in equalibrium during unaccelerated flight.

• In straight and level, unaccelerated flight
•                 lift = weight
•                 thrust = drag
49. Bernoulli's Principle
As the velocity of a fluid (such as air) increases, its pressure decreases.

54. YAW
side to side motion of the nose
55. PITCH
up and down motion of the nose
IT senses movement & displays a heading based on  a 360o azimuth with the final 0 omitted.

it is the primary source for heading information.

FAA: it must be aligned with themagnetic compass before flight.
57. Compass Varition
is the angular difference between the true and magnetic poles at  given point.
58. Compass Deviation
FAA: Compass error due to disturbances from magnetic fields of the airplane and it's electronic equipment.
59. Compass acceleration Error
FAA:In the NORTHERN hemisphere if you accelerate the plane the compass shows a turn to the north.

When you decelerate the compass will show  turn to the south.

• ONLY HAPPENS ON A EAST/WEST heading
• DOES NOT happen on a NORTH/SOUTH heading.

Remember: ANDS
60. Function of the magnetic compass during turns
FAA:when turning right the magnetic compass will show a deflection to the WEST when turning from the NORTH.

When turning left, the mgnetic compass will show a deflection EAST when turning from the NORTH.
61. Compass turning errors cause the compass to
