Radio Navigation

Question 0

What are the specs for low altitude VOR?

Answer 0

1000 - 18,000 AGL = 40 NM

Question 1

Within what frequency range do VORs operate?

Answer 1

108.0 - 117.5 MHz VHF band

Question 2

What are the specs for terminal VOR stations?

Answer 2

1000 – 12,000 AGL = 25 NM

Question 3

What are the specs for high altitude VOR stations?

Answer 3

1000-14,500 AGL = 40 NM
14,500-18,000 AGL = 100 NM
18,000-45,000 AGL = 130 NM
45,000-60,000 AGL = 100 NM

Question 4

What is it mean when a single coded identification received once every 30 seconds from a VORTAC station?

Answer 4

DME component is operative, VOR component is inoperative.

Question 5

Will all VOR stations have capability for providing distance information to aircraft equipment with DME?

Answer 5

No.

Question 6

The route of flight portion of IFR flightplan should list VOR navigation aids which are no further than what distance from each other?

Answer 6

Below 18,000 feet MSL, use aids not more than 80 NM.

Between 14,500 feet MSL and 17,999 feet MSL facilities not more than 200 NM apart maybe used.

Question 7

Within what frequency range do NDBs normally operate?

Answer 7

190-535 kHz

Question 8

When a radio beacon is used in conjunction with an ILS marker beacon, what is it called?

Answer 8

Compass locator

Question 9

What is a HSI?

Answer 9

Horizontal situation indicator:
Combination of two instruments.
Vertical heading indicator & VOR/ILS indicator.

Question 10

What’s is an RMI?

Answer 10

Radio magnetic indicator:
Rotating Compass card, double barred bearing indicator, single barred bearing indicator.
Compass card rotates as aircraft turns.

Question 11

What’s is DME?

Answer 11

Distance measuring equipment:
Provides distance and groundspeed information.
Reliable up to 199 NM.

Question 12

What frequency does a DME operate on?

Answer 12

960-1215 MHz

Question 13

Does DME provide slant or horizontal distance?

Answer 13

Slant distance

Question 14

To minimize DME slant range error how far from the facility should you consider the reading accurate?

Answer 14

Slant range error will be at a minimum if aircraft is one or more miles from facility for each 1000 feet of else to the above the facility.

Question 15

When is DME equipment required?

Answer 15

At and above FL 240

Question 16

What is RNAV?

Answer 16

Area navigation: provides enhanced navigational capability to the pilot.

Question 17

What is LORAN?

Answer 17

Long-range navigation:

Onboard computer capable of determining an aircraft’s position.

Question 18

Give a brief description of GPS.

Answer 18

Global positioning system:

Receiver tracks multiple satellites and determines a pseudo-range measurement then used to determine the user location.

Question 19

What are three functional elements of GPS?

Answer 19

Space element: Consists of 24 Navstar satellites. At least five satellites are in view at all times.

Control element: Consists of network ground-based GPS monitoring and control stations. To ensure accuracy of satellite positions and their clocks.

User element: consist of antennas/receivers on board aircraft providing positioning, velocity, precise timing to user

Question 20

Is there an alternate means of navigation appropriate to the route of flight required if using GPS navigation equipment under IFR?

Answer 20

Yes. The equipped with approved and operational alternate means of navigation. Is required when RAIM capability of GPS equipment is lost.

Question 21

What is the purpose of RAIM?

Answer 21

Receiver autonomous integrity monitoring:

Needs a minimum of five satellites

Question 22

If RAIM is lost, can you continue flight?

Answer 22

No.

Question 23

Where can a pilot obtain RAIM availability information?

Answer 23

Automated flight service station during preflight briefings.

FAA Briefers.

Question 24

Can handheld GPS receivers and GPS system certified for IFR operations be used for IFR operations?

Answer 24

No.
