Question 1 of 19

1. Question

When checking the course sensitivity of a VOR receiver, how many degrees should the OBS be rotated to move the CDI from the center to the last dot on either side?

5° to 10°.
10°to12°.
18° to 20°.

Question 2 of 19

2. Question

When using VOT to make a VOR receiver check, the CDI should be centered and the OBS should indicate that the aircraft is on the

090 radial.
180 radial.
360 radial.

Question 3 of 19

3. Question

How should the pilot make a VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface?

Set the OBS on 180° plus or minus 4°; the CDI should center with a FROM indication.
Set the OBS on the designated radial. The CDI must center within plus or minus 4° of that radial with a FROM indication.
With the aircraft headed directly toward the VOR and the OBS set to 000°, the CDI should center within plus or minus 4° of that radial with a TO indication.

Question 4 of 19

4. Question

An aircraft 60 miles from a VOR station has a CDI indication of one-fifth deflection, this represents a course centerline deviation of approximately

6 miles.
2 miles.
1 mile.

Question 5 of 19

5. Question

When the CDI needle is centered during an airborne VOR check, the omnibearing selector and the TO/FROM indicator should read

within 4° of the selected radial.
within 6° of the selected radial.
0° TO, only if you are due south of the VOR.

Question 6 of 19

6. Question

Which situation would result in reverse sensing of a VOR receiver?

Flying a heading that is reciprocal to the bearing selected on the OBS.
Setting the OBS to a bearing that is 90° from the bearing on which the aircraft is located.
Failing to change the OBS from the selected inbound course to the outbound course after passing the station.

Question 7 of 19

7. Question

To track outbound on the 180 radial of a VOR station, the recommended procedure is to set the OBS to

360° and make heading corrections toward the CDI needle.
180° and make heading corrections away from the CDI needle.
180° and make heading corrections toward the CDI needle.

Question 8 of 19

8. Question

To track inbound on the 215 radial of a VOR station, the recommended procedure is to set the OBS to

215° and make heading corrections toward the CDI needle. C. 035° and make heading corrections toward the COi needle. 215° and make heading corrections toward the COi needle.
215° and make heading corrections away from the CDI needle.
035° and make heading corrections toward the COi needle.

Question 9 of 19

9. Question

For IFR operations off established airways, ROUTE OF FLIGHT portion of an IFR flight plan should list VOR navigational aids which are no more than

80 miles apart.
70 miles apart.
40 miles apart.

Question 10 of 19

10. Question

Refer to figure 17 below. Which illustration indicates that the airplane will intercept the 060 radial at a 75° angle outbound, if the present heading is maintained?

4
5
6

Question 11 of 19

11. Question

Refer to figure 17 below. Which statement is true regarding illustration 2, if the present heading is maintained? The aircraft will

cross the 180 radial at a 45° angle outbound.
intercept the 225 radial at a 45° angle.
intercept the 360 radial at a 45° angle inbound.

Question 12 of 19

12. Question

Refer to figure 17 below. Which illustration indicates that the airplane will intercept the 060 radial at a 60° angle inbound, if the present heading is maintained?

6
4
5.

Question 13 of 19

13. Question

Refer to figure 17 below. Which illustration indicates that the airplane should be turned 150° left to intercept the 360 radial at a 60° angle inbound?

1
2
3

Question 14 of 19

14. Question

Refer to figure 17 below. Which is true regarding illustration 4, if the present heading is maintained? The airplane will

cross the 060 radial at a 15° angle.
intercept the 240 radial at a 30° angle.
cross the 180 radial at a 75° angle.

Question 15 of 19

15. Question

Effective navigation by means of GPS includes

determining the current status of all databases.
ensuring that ATC approves your planned route.
relying solely on the GPS for course information.

Question 16 of 19

16. Question

Why should pilots understand how to cancel entries made on a GPS?

Because GPS units frequently provide wrong or false information.
Because heavy workloads and turbulence can increase data entry errors.
Because published route names commonly change.

Question 17 of 19

17. Question

Reliance on GPS units

can cause pilots to lose proficiency in performing manual calculations of time, distance, and heading.
will increase a pilot's skill in navigating by visual reference.
does not decrease pilot workload.

Question 18 of 19

18. Question

The primary purpose of the direct-to button is to

provide waypoints to a given runway.
give routing to the nearest airport.
show the quickest way to fly to any given point.

Question 19 of 19

19. Question

Which button/feature provides information on the closest airport at any given time?

Direct-to.
Nearest.
Flight plan.
