chapter 1 preflight

Question 1

What type of errors is the altimeter subject to?

Answer 1

a. Mechanical errors - Differences of ambient pressures and temperatures
b. Inherent errors - non-standard temperatures and pressures

Question 2

Indicated altitude

Answer 2

altitude read directly from the altimeter (uncorrected) after it is set to the current altimeter setting

Question 3

True altitude

Answer 3

vertical distance of the aircraft above sea level (MSL). Airport, terrain, and obstacle elevations on aeronautical charts are true altitudes.

Question 4

Absolute altitude

Answer 4

vertical distance above the terrain, above ground level (AGL). An altimeter set to the proper pressure reading indicates 0 at touchdown.

Question 5

Pressure altitude

Answer 5

indicated altitude with altimeter set to 29.92. Used to compute density altitude & performance data

Question 6

Density altitude

Answer 6

pressure altitude corrected for variations from standard temperature

Question 7

What are the errors that the airspeed indicator is subject to?

Answer 7

Position error
Density error
Compressibility error

Question 8

Indicated airspeed

Answer 8

IAS is what is read off the ASI, uncorrected.

Question 9

Calibrated airspeed

Answer 9

CAS is the speed that the aircraft moving through the air, it is IAS corrected for errors, chart found in the POH

Question 10

Equivalent airspeed

Answer 10

CAS corrected for compressibility in the pitot tube

Question 11

True airspeed

Answer 11

TAS is CAS corrected for non standard pressures and temperatures

Question 12

PFD

Answer 12

Primary flight display. Contains all the information from the instruments on an easy to scan screen

Question 13

MFD

Answer 13

Multi function display. A display for navigation data, moving maps & aircraft system information. Can also be used as a PFD if needed

Question 14

AHRS

Answer 14

Attitude and heading reference system. Integrated flight system composed of three-axis sensors for heading, attitude and yaw information for an aircraft

Question 15

ADC

Answer 15

Air data computer. receives and processes ram air, static air and tempurature information from sensors to provide altitude, vertical speed, airspeed, and wind

Question 16

FMS

Answer 16

Flight management system. A computer system containing a database for programming routes, approaches and departures for the flight director/autopilot

Question 17

FD

Answer 17

Flight director. Electronic flight calculator that is shown on the PFD to help guide the pilot

Question 18

TAWS

Answer 18

Terrain awareness and warning system. Uses GPS to show aircraft trajectory with surrounding terrain

Question 19

TIS

Answer 19

Traffic information system. ground based traffic display that receives data from ATC radar and gives traffic alerts
