27
Q

This is the speed that you are reading directly from airspeed indicator

A

Indicated airspeed (IAS)

28
Q

Manufacturers use this airspeed as the basis for determining aircraft performance

A

Indicated airspeed (IAS)

29
Q

This is the indicated airspeed corrected for installation error

A

Calibrated airspeed (CAS)

30
Q

Any errors that interfere with the system that is reading total and static pressure are connected here

A

Calibrated airspeed (CAS)

31
Q

Calibrated airspeed is equal to _______________ in standard atmosphere at sea level

A

true airspeed

32
Q

What does KIAS stand for

A

Indicated Airspeed in Knots

33
Q

What does KCAS stand for

A

Calibrated Airspeed in Knots

34
Q

This is calibrated airspeed corrected for altitude and nonstandard temperature

A

True Airspeed (TAS)

35
Q

This is used for flight planning and is used when filing a flight plan

A

True Airspeed (TAS)

36
Q

As altitude of temperature increases, TAS increases to compensate for the decrease in air density. True or False

A

True

37
Q

This is the actual speed of the airplane over the ground

A

Ground Speed (GS)

38
Q

GS __________ with a headwind, GS __________ with a tailwind

A

decreases, increases

39
Q

State the instrument errors in pitot tube failure

A
  • Icing over the pitot tube
  • Trapped water in the lines
  • Leaks due to holes or loose fittings
  • Obstructions/ blockages
  • Taped or covered ports
40
Q

What is the instrument that measures the height of an aircraft above a given pressure level.

A

Altimeter

41
Q

This is a type of barometer which measures the vertical distance to the surface

A

Altimeter

42
Q

Where does the altimeter get readings from and through where?

A

from the static system (static port) and through the sealed aneroid wafers

43
Q

These function by measuring pressure differences which are displayed in terms of feet

A

Altimeters

44
Q

It is defined as station pressure reduced to sea level. It is only accurate only in the vicinity of the reporting station.

A

Altimeter Setting

45
Q

When it comes to changing the altimeter setting, the pilot registers changes in the small window called?

A

Kollsman Window

46
Q

What are the three types of altimeter settings?

A
  • QFE
  • QNH
  • QNE
47
Q

This is a barometric scale window of a sensitive altimeter used to adjust the altitude for the altimeter setting

A

Kollsman Window

48
Q

What is the range of the scale in Kollsman Window?

A

28.00’’ to 31.00’’ inches of mercury, or 948 to 1,050 milibars

49
Q

The height above the runway. It reads zero when you are on the runway and gives your height above it when you are airborne

A

QFE (“Field Elevation”)

50
Q

The height above sea level. It reads runway elevation when you are on the runway and is based on an altimeter setting adjusted until the station’s correct elevation above sea level is read

A

QNH (“Height Above Sea Level”)

51
Q

This is a pressure setting of 29.92 inches or 1013 hPa that will produce a standard atmosphere altitude and provides the basis for flight levels

A

QNE (“En Route”)

52
Q

In altimeter reading, the long pointer (with a triangle) measures altitude in intervals of what?

A

10,000 feet

53
Q

In altimeter reading, the wide pointer measures altitude in intervals of _________?

A

1,000 feet

54
Q

The medium, thin pointer measures altitude in intervals of ___________?

A

100 feet

55
Q

This is only displayed if the altitude are below 10,000 feet

A

Crosshatch flag

56
Q

State the five types of altitudes

A
  • Indicated Altitude
  • True Altitude
  • Absolute Altitude
  • Pressure Altitude
  • Density Altitude
57
Q

This is the altitude that is read directly from the altimeter when it is set to the current altimeter setting

A

Indicated Altitude

58
Q

The vertical distance of the aircraft above sea level-the actual altitude. It is often expressed as feet above mean sea level (MSL).

A

True Altitude

59
Q

What type of altimeter setting is true altitude?

A

QNH

60
Q

This is the vertical distance of an aircraft above the terrain, or above ground level (AGL).

A

Absolute Altitude

61
Q

What type of altimeter setting is Absolute Altitude?

A

QFE

62
Q

This is the altitude indicated when the altimeter setting window (barometric scale) is adjusted to 29.92 inHg. It is used to compute density altitude, true altitude, true airspeed (TAS)

A

Pressure Altitude

63
Q

What type of altimeter setting is Pressure Altitude?

A

QNE

64
Q

An inch error in the altimeter setting equals how many feet of altitude?

A

1000 feet of altitude

65
Q

From HIGH to LOW or from HOT to COLD

A

Look out below

66
Q

From LOW to HIGH or from COLD to HOT

A

Clear the Sky

67
Q

Trapped static pressure causes the altimeter to freeze at the altitude where the blockage occured

A

Static Port Blockage
