Q

What is a QDM?

A

Magnetic heading to a station

21
Q

What is a QDR?

A

Magnetic heading from a station

22
Q

What is a QUJ?

A

True heading to a station

23
Q

What is a QTE?

A

True heading from a station

24
Q

In VDF, what are the two magnetic headings?

A

QDM and QDR

25
Q

In VDF, what are the two true headings?

A

QUJ and QTE

26
Q

Of two types of NDB transmissions, what number indicates a long-range beacon?

A

1 in N0N A1A

27
Q

Of two types of NDB transmissions, what number indicates a short-range beacon?

A

2 in N0N A2A

28
Q

ADF bearings are considered what?

A

Magnetic

29
Q

Why are ADF bearings considered magnetic?

A

Because it is relative to the Directional Indicator which is Magnetic

30
Q

For an NDB, the ‘cone of silence’ occurs when the aircraft enters what zone?

A

40 degrees vertically displaced above the NDB

31
Q

During the day, ADF accuracy has what margin of error?

A

6 degrees

32
Q

VOR stands for?

A

VHF Omni-directional Range

33
Q

A specific magnetic bearing relative to a VOR is known as a what?

A

Radial

34
Q

An aircraft’s VOR receiver measures what to determine the radial?

A

Phase difference

35
Q

Radials are always referred to as what in relation to a VOR?

A

Bearings FROM the station

36
Q

Each small mark on a CDI indicates what?

A

2 degrees of displacement

37
Q

When will the TO/FROM flag change?

A

When the aircraft passes the radial that is perpendicular to the CDI radial

38
Q

CDI stands for?

A

Course Direction Indicator

39
Q

TO/FROM indicator simply indicates whether the aircraft is

A

On the same side of the VOR as the selected radial

40
Q

A VOR’s ‘cone of confusion’ carries what degree of vertical displacement?

A

50 degrees

41
Q

A VOR’s ‘total system’ error is

A

5 degrees

42
Q

VOR range is limited to..

A

Line of sight

43
Q

Simplified form of how DME is measured?

A

Round trip delay of aircraft’s UHF signal is measured

44
Q

How is DME initially measured?

A

An aircraft transmits a UHF signal

45
Q

When is the speed measurement and time to station on a DME only valid?

A

If the aircraft is flying directly to/from the station

46
Q

DME’s indicated distance is a measurement of what distance?

A

Slant range

47
Q

SSR uses a signal in whay frequency bracket?

A

UHF
