Airspeed Indicator measures?

Difference between dynamic and static pressure

2

Types of Airspeed

ICET/G
Indicated
Calibrated
Equivilant
True
Ground

3

Indicated Airspeed

Read off of ASI

4

Calibrated Airspeed

Indicated airspeed corrected for installation error

5

Equivilant Airspeed

Calibrated airspeed corrected for compressibility. Airspeeds above 180 KTS at or above 10,000FT MSL

6

True Airspeed

True airspeed corrected for non standard pressure

7

Types of Altitudes

PATID
Pressure
Absolute
True
Indicated
Density

8

Pressure Altitude

When 29.92 is set in Kolsman window

9

Absolue Altitude

Height above the ground (AGL)

10

True Altitude

Height above mean sea level (MSL)

11

Indicated Altitude

Read off of Altimeter

12

Density Altitude

Pressure Altitude corrected for non standard temperature

13

How does the ASI work?

Bellows connected to pitot tube, Static port connected to instrument case.

14

How does the Altimeter work?

Aneroid Wafers exand and contract as atmospheric pressure changes.

15

Compass Errors

ANDS
UNOS
Variation
Deviation
Osscillation

16

ANDS

Accelerate North
Decelerate South

Only when starting on E/W headings

17

UNOS

Undershoot North
Overshoot South

Only when turning to N/S headings

18

Variation

Angle difference between magnetic North and True North

19

Deviation

Magnitic fields created inside aircraft
