Flashcards in Avionics Deck (31):
1

Which component contains the auto pilot logic

MCPA

Modular central processor assembly

2

How many AVC’s are contained in the MCPA

2

AVC1 &2

Found in the system dialogue from the MCPA mode drop-down menu

3

Which components are the primary sensors

INS/GPS & ADU

Internal navigation system

Air data unit

4

How many ADU sensors are contained in the MCPA

3
The ADU contains the static pressure sensor dynamic pressure sensor and temperature sensor in a triple redundancy configuration!

Air data units communicate air pressure temperature and airspeed information for navigation calculations!

5

How long does it take for the INS to align an enter NAV mode

6 Min.

Aircraft configuration for ATLS, the INS will enter NAV mode automatically. Wait six minutes before moving the aircraft following powerup of the aircraft, for the INS initialization

Pg. 254

6

Name three things that indicate an INS is initializing

Navigation lights turn on and off every 10 seconds, various INS related warnings, and FOM 5000 m

7

What are the indications the INS is in NAV mode

INS reports navigation mode and FOM accuracy is less than 100 m

8

What does the MCPA automatically do to “vote in” Sensors upon completion of INS alignment

Sensor reset

Pg. 254

9

What does a sensor reset do

Reset MCPA voting logic

Pg 254

10

How many GPS satellites are required to calculate position

3

Pg 255

NOTE
Four satellites are required in to receive GPS altitude, however only three required to provide a position fixed

11

Which components back up INS/GPS

DMU, FVU, and DGPS

12

What are the three axes of flight

Lateral, longitudinal, vertical

13

Which axis of flight is controlled by ailerons

longitudinal

14

Which axis of flight is controlled by elevators

Lateral

15

Which acts as a flight control by Rudders

Vertical

16

What system automatically moves our rudders with the ailerons in order to make coordinated turns

Aileron rudder interconnect

(ARI)

17

Which flight control services increase an aircraft rate of descent without increasing airspeed

Flaps

18

Which flap setting places the flaps at 30° angle

Emergency

19

When and EO is in control of the aircraft which auto pilot level is engaged

Position sticks

20

When in AO is in control of the aircraft Which auto pilot level is engaged

Knobs

21

When is the rate stick auto pilot level Used

Never

22

Which primary sensor does the MCPA use to limit aileron movement when positions sick auto pilot level is engaged

INS

23

Which control loop malfunction is based on a 12 second command and report

Altitude

24

When will the airspeed control loop malfunction appear

Airspeed command and report differ by at least five knots for more than 17 seconds

25

What control loop malfunction is a rate of climb of less than 100 ft./min. for more than 12 seconds

Altitude control loop malfunction

26

What must a shelter be in control of it order for a Heading control loop malfunction to appear

Heading

27

When will the heading control Loop malfunction appear

Heading command and report differ by at least 4° for more than 52 seconds

28

When are an aircraft calculator wins accurate

Automatic flight mode, straight and level flight, for two minutes

29

What navigation mode is reported immediately following a loss of all GPS

INS Primary

30

What navigation mode is reported if an INS fails

GPS

31

While flying in the local pattern with ground antennas in OMNI, your aircraft loses signal from all GPS satellites. What does the FOM Accuracy half to degrade to in order for your aircraft to stop using it’s INS for navigation

200 meters
