130 NM range.

20
Q

What is the range and altitude coverage of a VOR Low (VL) from 1,000 feet to 5,000 feet?

A

40 NM range.

21
Q

What is the range and altitude coverage of a VOR Low (VL) from 5,000 feet to 18,000 feet?

A

70 NM range.

22
Q

How many layers of coverage does a VOR High (VH) service volume have?
____ layers, ranging from _______ feet to_______ feet.

A

Five layers, ranging from 1,000 feet to 60,000 feet.

23
Q

How can you determine the service volume type of a VOR station?

A

Check the chart supplement for the class in parentheses.

24
Q

What does the Distance Measuring Equipment (DME) indicate?
It indicates ____________ ____________ distance, the straight-line distance between the ____________ at altitude and the ____________ transmitter on the ground.

A

It indicates slant range distance, the straight-line distance between the aircraft at altitude and the DME transmitter on the ground.

25
Q

When is slant range error most significant in DME readings?

A

At high altitudes very close to the VOR station.

26
Q

At 6,000 feet AGL directly above a station, what will the DME read?

A

The DME will read 1.0 NM.

27
Q

How is DME distance displayed?

A

In tenths of a mile.

28
Q

When does the difference between slant range and ground distance become apparent in DME readings?
When the aircraft is within ___ mile of the station for every _____feet AGL in altitude.

A

When the aircraft is within one mile of the station for every 1,000 feet AGL in altitude.

29
Q

What does the speed displayed by some DME units indicate?

A

The rate at which the aircraft is getting closer to or moving away from the station.

30
Q

What will the DME speed read when flying on a DME arc?

A

The speed will read zero.

31
Q

How can an IFR-approved GPS be used in relation to a traditional DME?

A

It can be used in place of a traditional DME.

32
Q

What is the key difference between GPS distance and DME slant range distance?

A

GPS distance is ground distance, while DME shows slant range distance.
