Automatic flight control systems (AE)

Question 1

At missed approach og þú “depressar” TOGA switch, hvað gerist? (tveir þættir)

Answer 1

1) Autothrottle selects go around power.

2) Autopilot flies the GA maneouver.

Question 2

Ef þú ert með FDC í ALT HOLD mode, hvaða faktorum fylgist hún með (tveir þættir)?

Answer 2

1) altitude deviation

2) pitch attitude

Question 3

In a flight director (FD) (command bar type), the vertical bar is associated with the roll/pitch channel and why?

Answer 3

Associated with the roll channel.

Getur hugsað þetta þannig að ef þú rollar vélinni þá færist vertical bar. (Þetta er fjólublái krossinn, ef þú rollar t.d. á rétta átt þá er fjólubláa vertical línan komin í miðjuna).

Question 4

Hvað er roll-out mode að gera í autoland?

Answer 4

Gerir vélinni kleyft að halda centerline á braut eftir lendingu.

Question 5

Hvaða græja fylgist með í hvaða phase autoland þú ert í?

Answer 5

Radio altimeter

Question 6

Notar autopilot m.a. inputs frá:

1) ADC
2) Attitude reference system
3) ILS receiver
4) Mode control panel

Answer 6

allt

Question 7

Flight director er í LOC mode og certical command bar er deviating to the left, þetta þýðir að aircraft:

a) must be rolled to the left
b) is right of the LOC axis

Answer 7

a) must be rolled to the left

Málið er að vertical command er ekki að segja þér NEITT um hvar þú ert, bara hvað þú þarft að GERA.

Question 8

The guidance functions of a autopilot consists in:

a) stabilizing and monitoring the movements around the centre of gravity
b) monitoring the movements of the centre of gravity in the three dimensions of space.

Answer 8

b) monitoring the movements of the centre of gravity in the three dimensions of space.

Question 9

Í “command bars” type of flight director the

a) vertical bar may be associated with the pitch channel
b) horizontal bar is associated with the pitch channel

Answer 9

b) horizontal bar is associated with the pitch channel

Question 10

To allow the coupling of a duel channel flight director.. both autopilot channels must be selecten ON/OFF?
(PS þetta er bara memory item því þessi spurning er víst alveg rugluð)

Answer 10

ON

Question 11

The horizontal command bar of a flight director gives information about the direction and the amplitude of the corrections to be applied on the ____ of the aircraft.

Answer 11

pitch

Question 12

Varðandi fail-passive flight control system; In case of failure there is /is not significant deviation of flight path or attitude.
Landing is not/is not completed automatically

Answer 12

no significant deviation but landing is not completed automatically.

Question 13

Vertical flight path mode of an autopilot system are:

a) pitch attitude hold
b) altitude hold
c) track hold
d) glide slope intercept and track

Answer 13

b) altitude hold

d) glide slope intercept and track

Question 14

A semi-automatic landing system disconnects itself automatically when?

Answer 14

at decision height.

Question 15

during an automatic landing, the autopilot maintains a vertical speed depending on the radio altimeter height, with a constant vertical speed about __ feet/second during the last phase of the flare manoeuvre.

Answer 15

2

Question 16

The flight director indicates the ___ ___ path to reach a selected radial.

Answer 16

optimum instantaneous

Question 17

Ef þú ert með autoland í stað þess að lenda sjálfur, um hvaða aðstæður í umhverfinu gilda þá strangari reglur?

Answer 17

Headwind/crosswind, pressure altitude, runway contamination.

Question 18

In the even of a failure, a fail-operational flight control system will operate as a..

Answer 18

fail-passive system.

Question 19

Ef það klikkar eitthvað, það er ekkert deviation í flight path eða neitt slíkt en en lendingin er samt ekki automatic, slíkt kerfi er fail-____

Answer 19

passive

Question 20

inner loop control system povides stabilization about ___.

Answer 20

a single axis.

Question 21

Í flight director, the horizontal bar is associated with the ___ channel.

Answer 21

pitch

Question 22

Hvernig þarftu að hugsa dæmin í flight director (commands bar type) til að fá þau rétt þegar það er verið að spyrja þig um vertical/horizontal bar is associated with pitch/roll channel.

Answer 22

Í fyrsta lagi þarftu að hugsa um bæði vertical/lateral og hvernig þetta snýr því ég hef oft ruglast á þessu. Svo þarftu að ímynda þér skekkju á þessu og svarið liggur í hvort þú þarft að banka eða pitcha til að fá línuna fyrir miðju.

Question 23

Getur fail-passive autopilot lent?

Answer 23

Nei, fail operational getur lent

Question 24

Hvað þarftu marga autopilota til að teljast fail passive?

Answer 24

1, til að vera fail operational þá þarftu 2.

Question 25

Er IAS og Mach hold í autopilot flight path mode?

Answer 25

já

Question 26

Er intertial heading hold í autopilot flight path mode?

Answer 26

já

Question 27

Er horizontal wing holding í autopilot flight path mode?

Answer 27

nei

Question 28

Er pitch attitude holding í autopilot flight path mode?

Answer 28

nei

Question 29

Er speed hold í lateral flight path mode í autopilot?

Answer 29

Nei

Question 30

Hvað kallast kerfið þegar það er einn autopilot vs. tveir autopilot?

Answer 30

1: Fail-passive

2. Fail-operational

Question 31

Hvað af þessu er input inn í auto-pilot?

a) ADC b) attitude reference system c) ILS receiver d) Mode control panel

Answer 31

allt
