Question 1

Hvad er lokaliseret systemets funktion under en landing?

Answer 1

Lokaliseret systemet hjælper piloterne med at justere deres position i forhold til landingsbanens centerlinje ved at sende præcise signaler.

Question 2

Hvad bruges frekvenserne 150 Hz og 90 Hz til i glidebanesystemet?

Answer 2

De angiver, om flyet er for højt eller for lavt i forhold til den optimale indflyvningsvinkel.

Question 2

Hvad er forskellen mellem CAT 1, 2 og 3 landingskategorier?

Answer 2

CAT 1 kræver moderat sigtbarhed, CAT 2 kræver lav sigtbarhed, mens CAT 3 tillader autolanding under meget lav sigtbarhed.

Question 2

Hvad er et Non-Directional Beacon (NDB), og hvordan bruges det?

Answer 2

NDB er et ældre navigationssystem, der sender et radiosignal, som piloten kan bruge til at finde en station. Det er mindre præcist end moderne systemer.

Question 3

Hvordan bruger flyvelederen radar til at overvåge fly?

Answer 3

Flyveledere bruger primær radar til at se objekter og sekundær radar til at få oplysninger om flyets identitet og højde.

Question 4

Hvad er forskellen på frekvens og bølgelængde?

Answer 4

Frekvensen er antallet af svingninger pr. sekund, mens bølgelængden er afstanden mellem to bølgetoppe. Jo højere frekvensen er, jo kortere bliver bølgelængden.

Question 5

Hvordan påvirkes radiosignaler af miljøet?

Answer 5

Radiosignaler kan blive blokeret af bygninger og andre forhindringer og kan også påvirkes af atmosfæriske forhold.

Question 6

Hvad er forskellen mellem frekvensmodulation (FM) og amplitudemodulation (AM)?

Answer 6

FM ændrer frekvensen af bæresignalet, mens AM ændrer signalets amplitude.

Question 7

What is the typical power output of an aircraft generator per engine?

Answer 7

400 watts per engine.

Question 8

Why do larger aircraft transmit stronger radio signals?

Answer 8

Larger aircraft have higher energy input, allowing for stronger signals.

Question 9

Why is amplitude modulation (AM) commonly used in aviation?

Answer 9

It allows users to detect multiple transmissions and prioritize the stronger signal.

Question 10

What is the advantage of digital modulation in aviation communication?

Answer 10

Digital modulation provides clearer signals and reduces interference.

Question 11

How do noise-canceling headsets work in aviation?

Answer 11

They detect constant noise and generate an inverse wave to cancel it out.

Question 12

What weather conditions can affect radio signal transmission?

Answer 12

Thunderstorms and dense clouds can reflect electromagnetic waves, leading to communication loss.

Question 13

Why are multiple antennas used on aircraft?

Answer 13

To ensure consistent communication, even when obstacles block direct transmission paths.

Question 14

What is VHF radio, and how is it used in aviation?

Answer 14

VHF radio is used for aircraft communication, modulating signals based on amplitude or frequency.

Question 15

What is the primary function of primary radar?

Answer 15

To send out energy signals and measure the time it takes for reflections to return, calculating the distance and direction of objects.

Question 16

What does secondary radar provide that primary radar does not?

Answer 16

Aircraft identification and altitude information, communicated via transponder signals.

Question 17

What happens when radar signals encounter the Earth’s curvature?

Answer 17

Aircraft can disappear from radar coverage due to the Earth’s curvature, limiting how far radar can see.

Question 18

What is the relationship between frequency and radar resolution?

Answer 18

Higher frequencies offer better resolution but shorter range, while lower frequencies can detect objects farther away but with less detail.

Question 19

How is radar calibration important for air traffic control?

Answer 19

It ensures radar accuracy by aligning the radar’s signals to track objects correctly.

Question 20

What are the limitations of radar in detecting objects?

Answer 20

Terrain, weather, and physical obstacles can block radar signals, affecting its accuracy.

Question 21

What is the main limitation of primary radar compared to secondary radar?

Answer 21

Primary radar can only detect the presence of objects but doesn’t provide additional data like aircraft ID or altitude.

Question 22

Hvad bruges ATIS til?

Answer 22

ATIS giver automatisk opdaterede informationer om vejrforhold og banestatus til piloter.

Question 23

Hvad er fordelene ved CPDLC?

Answer 23

CPDLC tillader digital kommunikation mellem fly og kontroltårne, hvilket reducerer manuel radioanvendelse og minimerer fejl.

Question 24

Hvad betyder “Wilco” i datalink-kommunikation?

Answer 24

“Wilco” betyder, at piloten har modtaget og vil efterkomme instruktionen.

Question 25

Hvordan forbedrer automatisering af rutinebeskeder sikkerheden i luftfart?

Answer 25

Automatiserede beskeder reducerer risikoen for misforståelser og gør kommunikationen mere præcis og effektiv.

Question 26

Hvad er ACARS, og hvad bruges det til?

Answer 26

ACARS er et kommunikationssystem, der bruges til at sende informationer mellem fly og kontroltårne, herunder ruteoplysninger og vedligeholdelsesdata.
