1. What distance is displayed by the DME indicator?
- Correct Answer: Slant range distance in NM
2. Where does the DME indicator have the greatest error between ground
distance to the VORTAC and displayed distance?
- Correct Answer: High altitudes close to the VORTAC
3. (Refer to Figure 240.) How should a pilot determine when the DME at
Price/Carbon County Airport is inoperative
- Correct Answer: The airborne DME may appear normal, but there will be no
code tone
4. (Refer to Figure 240.) How should a pilot determine when the DME at PUC
airport is inoperative?
- Correct Answer: The airborne DME may appear normal, but there will be no
code tone
,5. Which DME indication should you receive when you are directly over a VORTAC
site at approximately 6,000 feet AGL?
- Correct Answer: 1
6. As a rule of thumb, to minimize DME slant range error, how far from the facility
should you be to consider the reading accurate?
- Correct Answer: One or more miles for each 1,000 feet of altitude above the
facility
7. When a VOR/DME is collocated under frequency pairings and the VOR portion
is inoperative, the DME identifier will repeat at an interval of
- Correct Answer: 30 second intervals at 1350 Hz
8. What is the meaning of a single coded identification received only once
approximately every 30 seconds from a VORTAC?
- Correct Answer: The DME component is operative and the VOR component
is inoperative
9. (Refer to Figure 192.) As a guide in making range corrections, how many
degrees of relative bearing change should be used for each one-half mile
deviation from the desired arc?
- Correct Answer: 10 degrees to 20 degrees
10. How does a pilot determine if DME is available on an ILS/LOC?
,- Correct Answer: IAP indicate DME/TACAN channel in LOC frequency box
11. Which data must be recorded in the aircraft log or other appropriate log by a
pilot making a VOR operational check for IFR operations?
- Correct Answer: Place of operational check, amount of bearing error, date of
check, and signature
13. What record shall be made in the aircraft log or other permanent record by
the pilot making the VOR operational check?
- Correct Answer: The date, place, bearing error, and signature
14. When making an airborne VOR check, what is the maximum allowable
tolerance between the two indicators of a duel VOR system (units independent of
each other except the antenna)?
- Correct Answer: 4 degrees between the two indicated bearings of a VOR
16. (Refer to Figure 76.) Which indication would be an acceptable accuracy check
of both VOR receivers when the aircraft if located on the VOR receiver checkpoint
at the Helena Regional Airport?
- Correct Answer: C
17. While airborne, what is the maximum permissible variation between the two
indicated bearings when checking one VOR system against the other?
- Correct Answer: 4 degrees between the two indicated bearings to a VOR
, 18. (Refer to Figure 81.) When checking a dual VOR system by use of a VOT, which
illustration indicates the VOR's are satisfactory
- Correct Answer: 1
19. How should the pilot make a VOR receiver check when the aircraft is located
on the designated checkpoint on the airport surface?
- Correct Answer: Set the OBS on the designated radial. The CDI must center
within plus or minus 4 degrees of that radial with a FROM indication
20. (Refer to Figure 82.) Which is an acceptable range of accuracy when
performing an operational check of dual VOR's using one system against the
other?
- Correct Answer: 4
21. Where can the VOT frequency for a particular airport be found?
- Correct Answer: Only in the Chart Supplements U.S.
22. Which indications are acceptable tolerances when checking both VOR
receivers by use of the VOT?
- Correct Answer: 176 degrees TO and 003 degrees FROM, respectively
In which publication can the VOR receiver ground checkpoint(s) for a particular
airport be found?
- Correct Answer: Chart Supplement U.S.
Which is the maximum tolerance for the VOR indication when the CDI is centered
and the aircraft is directly over the airborne checkpoint?
