Q

How do you calculate the bearing to and from an NDB (2)?

17
Q

How does Thunderstorms affect NDB?

A

The electrical discharge will attract the needle to point to the Thunderstorm, rather than the NDB.

18
Q

Name three details needed by a Pilot to use an NDB effectively?

A
  • Frequency.
  • Identification Code.
  • Any Limitations.
19
Q

What symbol is used to identify a limitation with a NDB? What should the Pilot then look up?

A
  • Asterisk (*).

- Check ERSA for more information on limitation.

20
Q

How can a Pilot tell if the Aircraft is close to an NDB?

A

Increased sensitivity of the ADF indicator needle.

21
Q

How do you convert the ADF reading from Bearing to NDB to Bearing from NDB?

A

Minus 180 from figure (if bearing is greater than 360, minus 360).

22
Q

What does VOR stand for?

A

VHF Omnidirectional Radio Range.

23
Q

What is a VOR?

A

Ground-based transmitter and an airborne receiver/visual display.

24
Q

What frequency band does VORs operate in and it’s channel spacing (2)?

A
  • 108 to 118 MHz.

- Channel spacing of 50 KHz.

25
Q

Name three purposes VOR can be used for?

A
  • Establishing a position line.
  • Fixing a Position.
  • Tracking to/From/Homing to a VOR.
26
Q

What are the imaginary lines radiating from the VOR called and how are their identified (2)?

A
  • Radials.

- Magnetic Bearing from the Transmitter.

27
Q

What does OBI stand for?

A

Omni Bearing Indicator.

28
Q

What does OBS stand for?

A

Omni Bearing Selector.

29
Q

What’s the purpose of an OBS?

A

Enables a Pilot to set Track Required (to the VOR station).

30
Q

What does CDI stand for?

A

Course Deviation Indicator.

31
Q

What is the Deviation Scale on the VOR indicator?

A

A scale of 5 dots either side of the central position with each dot representing 2° of displacement from Track Required.

32
Q

What are the TO/FROM flags on the VOR indicator used for?

A

To sure the Bearing of the VOR station.

33
Q

What’s the usable range of a VOR below 5000ft?

A

60 NM.

34
Q

What’s the usable range of a VOR between 5000 and 9999ft?

A

90 MN.

35
Q

What’s the usable range of a VOR between 10 000ft and 14 999ft?

A

120 NM.

36
Q

What’s the usable range of a VOR between 15 000ft and 19 999ft?

A

150 NM.

37
Q

What’s the usable range of a VOR above 20 000ft?

A

180 NM.

38
Q

Name three details needed by a Pilot to use VOR effectively?

A
  • Frequency.
  • Identification Code.
  • Any Limitations.
39
Q

True or False. The CDI will move left or right if wind is affecting the Aircraft?

A

True.

40
Q

Which system is more accurate ADF/NDB or VOR?

A

VOR.

41
Q

What is Relative Bearing of a NDB?

A

Direction of the Station from the Aircraft’s Position.

42
Q

What is Magnetic Bearing of a NDB?

A

The Position of the Station from Magnetic North.
